Best Of :: Food & Drink
Even in a city known for its massively delicious Gulf Coast oysters, this Montrose hot spot's sexy oyster appetizer shines. Grilled in the shell, the half dozen bivalves are terribly messy and completely decadent, with chunks of bacon, Texas pecan pesto, pico de gallo and lightly browned Parmesan smothered on top. The oyster meat is only enhanced by the tasty toppings, as it remains as briny, sweet and succulent as ever. Of course, if you're a purist, a stellar selection of raw oysters are available by the dozen and half dozen as well.
Head to this Heights kitchenette for not one, not two, but four drool-worthy skillets of macaroni and cheese. Each dish comes hot and bubbling with a crisp, buttery crust and molten, gooey core. Go au naturel with the classic American and aged cheddar skillet; dive head-first into one loaded with sweet and succulent lobster meat and herbs; or go for the gold with a sausage, bacon and chile-loaded affair to remember. An always changing mac of the day — which has been known to include everything from chili-cheese dogs and tater tots to smoked salmon and cream cheese — rounds out the fantastically cheesy quartet.
The Urban Harvest Farmers Market at Eastside Street is the place to be on Saturday mornings. From 8 a.m. to noon, numerous vendors set up stations to serve their specialty goods, be they fruits, vegetables, macarons, breads, cheese, coffee or olive oil. You can purchase groceries from local producers, such as Atkinson Farm, Airline Seafood, Tavola Pasta and Tejas Heritage Farm, or grab a few desserts and prepared foods from Sinfull Bakery, Shade and Canopy, and Revival Market. If you miss the market on Saturday, you can stop by on Sunday as well, but there are fewer vendors then.
My Food Park HTX opened in late 2013 and brought a cornucopia of food-truck cuisine to the west Houston Energy Corridor. With three and a half acres of land, there's always a place to sit and dig into your food — not many food-truck parks have such relaxing seating. The lineup of trucks changes each day, but you can always count on My Food Park HTX to have movie nights each Friday and Saturday, as well as other special themes throughout the week, including Hump Day Wednesdays and Magical Mondays. Pop a squat at a picnic table for an afternoon weekday lunch, or kick off your weekend with dinner and a movie. Stay late on Saturdays to munch on sweets from the likes of Zeapod Cakery and Sno Cone City HTX.
If you want killer frites with house-made roasted garlic aioli, a fantastic warm goat cheese and hazelnut salad, or classic boeuf bourguignon, get your butt to this French restaurant in Rice Village. Café Rabelais isn't open at all hours of the day, but when it is, these folks are dishing out incredible food in a quaint and rustic French country restaurant. Satisfy any midday hunger pangs with a braised pork shoulder sandwich with honey thyme sauce, pickled onions and carrots for less than $10, or stick to the daily selections of fish and quiche. The menu changes daily, but that's to ensure each dish uses the freshest ingredients. The vanilla ice cream profiteroles or a succulent poached pear are a great way to end a romantic evening.
Rebecca Masson, a.k.a. The Sugar Fairy, made a name for herself nationally as a competitor on Top Chef: Just Desserts in 2011, but she also has grabbed Houston's attention with exquisite treats from her custom bake shop, Fluff Bake Bar. Various coffee shops and markets in the city sell her unfrosted cakes, cookie sandwiches and French macarons in surprising flavors, such as Werther's Caramel. Her edgy style and adventurous palate help her create finger-licking-good sweets you most certainly want to pair with a glass of milk — or wine. Recently, Masson announced she will open a brick-and-mortar bakery in Midtown after a successful Kickstarter campaign, and along with her delicious cookies, cakes and brownies, she'll be serving wine and beer. Soon you'll have a central place to grab Masson's beautiful and flavorful desserts, rather than searching the city for one of those comforting Fluffernutters.

Metastable and somatically heritable patterns of DNA methylation provide an important level of genomic regulation. In this article, we review methods for analyzing these genome-wide epigenetic patterns and offer a perspective on the ever-expanding literature, which we hope will be useful for investigators who are new to this area. The historical aspects that we cover will be helpful in interpreting this literature and we hope that our discussion of the newest analytical methods will stimulate future progress. We emphasize that no single approach can provide a complete view of the overall methylome, and that combinations of several modalities applied to the same sample set will give the clearest picture. Given the unexpected epigenomic patterns and new biological principles, as well as new disease markers, that have been uncovered in recent studies, it is likely that important discoveries will continue to be made using genome-wide DNA methylation profiling.
In 1942, Waddington defined epigenetics as the development of phenotypes from genotypes [1]. Since then, the term has taken on a specific molecular meaning, mostly referring to the patterning of DNA methylation and histone modifications in chromosomes. Epigenetic patterns are largely maintained during somatic cell proliferation, and are important in diverse physiological and pathophysiological phenomena. Among the various types of epigenetic modifications of the genome, DNA methylation is certainly one of the most stable. Methylation of DNA in mammalian cells is generally restricted to the 5 position of the pyrimidine ring of cytosine residues located in CpG dinucleotides (5-methylcytosine [5-mC]). In mammalian genomes, CpG dinucleotides are somewhat depleted on average, but are found densely clustered within sequences known as CpG islands (CGIs). These CGIs are typically in the range of 0.5–2 kb in size and located within 1 kb of transcription start sites. Under normal circumstances most, although not all, CGIs are unmethylated [2–4]. In contrast to CGIs, which are usually protected from methylation, in the remainder of the mammalian genome a high percentage of CpG dinucleotides, both in unique sequences and repetitive elements, are found to be variably to densely methylated [4,5]. DNA methyltransferase enzymes are responsible for creating (i.e., de novo methylation; DNA methyltransferase [DNMT] 3a, DNMT3b) and propagating (i.e., maintenance methylation; DNMT1) tissue-specific patterns of CpG methylation in the human genome (reviewed in [6,7]). As shown in experiments with knockout mice, each of these enzymes is essential for viability of the conceptus to term. Once established, the faithful transmission of methylation patterns to daughter cells is thought to be primarily due to DNMT1 activity and, consistent with this role, the DNMT1 enzyme localizes to DNA replication foci in the nuclei of S-phase cells [8]. The other two enzymes play greater roles in de novo methylation. Interestingly, Métivier et al. reported that DNMT3a and DNMT3b can also actively demethylate 5-mC through deamination [9,10]. On the other hand, Rai et al. suggested that the 5-mC removal in zebrafish embryos is mediated through two enzymatic reactions, namely the deamination of 5-mC by deaminase (AID) and the reparation of G:T mismatch by thymine glycosylase (Mbd4) [11]. For more discussion of this important topic of DNA demethylation, we refer interested readers to a recent review article [12].
A large body of research findings has demonstrated that epigenetic aberrations in cancer cells significantly contribute to tumor initiation, invasion, metastasis and resistance to chemotherapy (reviewed in [13,14]). Silencing of tumor suppressor genes by promoter hypermethylation has been commonly observed in a number of cancers including, but by no means restricted to, colon, bladder, stomach, breast, uterine and renal carcinomas [13,15,16]. This phenomenon is functionally quite important, and in some types of cancers, including gastric carcinomas, it appears that tumor suppressor genes are inactivated more frequently by their promoter hypermethylation than by mutations [17]. Despite hypermethylation in promoter-associated CGIs, many tumors exhibit overall genomic hypomethylation, affecting nonisland sequences prominently, including repetitive elements and the pericentromeric regions [14,18]. In addition to its role in silencing tumor suppressor genes by de novo methylation in malignant cells, DNA methylation is medically important for several reasons, as will be discussed.
Based on the fact that some chemicals can interfere with DNA methyltransferase activity and thereby revert hypermethylated DNA to a hypomethylated state in mammalian genomes, demethylating drugs have been actively studied and validated for clinical applications [19]. Some of them, such as decitabine, or 5-aza-2′-deoxycytidine, are effective anticancer agents in some tumor types, and are now widely used on low-dose schedules, for example to prolong transfusion independence and survival in myelodysplastic syndrome.
DNA methylation enforces the selective silencing of one parental allele at imprinted loci in normal human tissues. When this dose-regulating mechanism goes awry, owing to mistakes in DNA methylation early in development ('epimutations'), the result can be any of several well-characterized epigenetic diseases, including the growth disorders Beckwith–Wiedemann syndrome and Silver–Russell syndrome, the neurodevelopmental disorders Angelman syndrome and Prader–Willi syndrome, and the endocrine disorders transient neonatal diabetes mellitus and Albright osteodystrophy. In most of these disorders, some cases are due to mutations (point mutations, microdeletions and large-scale deletions) in the relevant imprinted genes or imprinting control sequences, while other cases are due to epimutations – that is, altered methylation without any mutation in the DNA sequence. DNA methylation is also a mechanism for 'locking-in' the silent state of genes on the inactive X-chromosome. Based on recent publications describing unique methylation patterns in human and mouse stem cells, changes in DNA methylation play a role in the differentiation of stem cells into their committed and mature cellular progeny [20].
DNA methylation is increasingly being studied in complex human diseases beyond cancer and the imprinting disorders. Altered CpG methylation may have an important role in propagating adverse changes in gene expression in intrauterine growth restriction and pre-eclampsia, common neuropsychiatric disorders and age-related dementias such as Alzheimer's disease, atherosclerosis, diabetes and the metabolic syndrome, and potentially also in non-neoplastic lung diseases such as pulmonary fibrosis.
Here we review currently available and emerging laboratory methods for investigating DNA methylation patterns in health and disease. We emphasize cancer research, but the methods are equally applicable to other disease states. Current research in epigenetics is largely driven by novel technologies [21], and over the past decade, studies of DNA methylation have grown dramatically, and become one of the most dynamic and rapidly developing fields in molecular biology. Most approaches for large-scale methylation profiling rely on an initial genomic fractionation step followed by analysis of methylation patterns across the genome by microarray-based or sequencing-based approaches. Previously, microarrays for this purpose contained clones from libraries of CGIs [22–24]. As the field progressed, more comprehensive global approaches were accomplished using whole-genome comparative genomic hybridization tiling arrays or bacterial artificial chromosomes arrays [25–28]. To achieve global epigenetic profiling, a variety of commercial microarrays are now available. Whole-genome arrays containing overlapping oligonucleotides tiling through large areas of mammalian genomes, including but not restricted to promoter regions, are available from NimbleGen (Roche, Basel, Switzerland), Agilent (CA, USA) and Affymetrix (CA, USA). These platforms have been used successfully for analyzing DNA methylation, typically with probes made from DNA fractionated by methylation-sensitive restriction-enzyme treatment and affinity purification of methylated DNA by either methyl-binding proteins or methylated DNA immunoprecipitation (MeDIP) [24,29–31]. These approaches will likely remain a mainstay in mammalian epigenetics for some time, as they have major advantages of dense genomic coverage and high sample throughput at a reasonable cost.
Before discussing each type of genomic microarray and its applications, we need to describe in more detail the methods of genomic fractionation and probe preparation for identifying methylated and unmethylated DNA sequences. Choices for this purpose are: genomic DNAs can be treated with methylation-sensitive restriction endonucleases, which discriminate sequences based on methylation status; and DNA can be immunoprecipitated by antibodies that recognize methylcytosine or processed by affinity purification on methyl-binding protein beads, such that the resultant DNA is enriched for methylated sequences. Another nonfractionation approach, with different technical advantages compared with the above fractionations, is to use sodium bisulfite, which converts unmethylated cytosines into uracil residues without changing methylated cytosines. This is an important approach, as bisulfite sequencing is considered to be the gold standard for validating DNA methylation patterns.
As one of the most promising technologies for genomic analysis, next-generation (NextGen) sequencing is just beginning to take center stage as another approach in DNA methylation profiling. We will discuss this methodology and its application in studying DNA methylation in a later section. Some of the representative DNA methylation methods included in this review are illustrated in Figures 1–3, and we will explore each of them in more detail.
The site-specificity and methylation dependence of several available restriction enzymes make restriction digestion a powerful approach for genomic fractionation. In principle, these technologies permit only one of the two fractions (either methylated or unmethylated) to remain intact after the restriction digestions, and subsequently those intact probes can be labeled and hybridized to an array. By contrast, fragments that have been cut at internal sites fail to amplify and drop out from this genomic representation. For example, as shown in Figure 1A, Huang et al. developed differential methylation hybridization (DMH) arrays by combining restriction endonucleases and microarrays for high-throughput examination of the methylation status of CGIs in human genomes [22,32–34]. In these studies, genomic DNA was fragmented by restriction with MseI, a four-base cutter that cleaves bulk DNA into small fragments (<200 bp). This endonuclease recognizes sequences that rarely occur within GC-rich regions, leaving most CGIs intact. Then, the restricted fragments were ligated to synthetic linkers and further restricted with methylation-sensitive endonucleases, BstUI and/or HpaII. The BstUI was selected for the methylation analysis because more than 80% of CGIs contain BstUI sites. The BstUI-treated DNAs were used as templates for the subsequent linker-dependent PCR. Methylated DNAs resist the restriction digestions, and hence can be amplified. By contrast, the unmethylated DNAs were digested by the endonucleases and failed to be amplified. The resulting PCR products were next labeled with fluorescent dyes. In general, Cy3 dye was used for DNA from control normal patients, while Cy5 dye was used to denote DNA from the patients with cancer. Equal amounts of final amplicons from both groups were mixed well and overlaid on a DMH microarray slide upon which the human CGI library probes were printed. After stringent hybridization, weak or unbound amplicons were eliminated by extensive washing and the resulting microarray slides were subject to high-resolution fluorescence scanning using a laser beam. The ratio of Cy5 over Cy3 intensities would reflect the methylation status in the cancer group relative to that in the normal counterparts within each locus.
To judge the potential false discoveries in this method, a methylation-insensitive isoschizomer of HpaII, namely MspI, can be employed in a control reaction. This methodology was applied for profiling promoter methylation in 8091 human genes [35]. Fukasawa et al. employed a similar approach and carried out promoter methylation studies in human lung cancer [36]. In their studies, the methylated HpaII-resistant DNA fragments and MspI-cleaved products were amplified and labeled with Cy3 and Cy5, respectively, and then were cohybridized to microarrays containing promoters of 288 cancer-related genes [36]. By using the similar restriction fractionation approach, HpaII tiny fragment enrichment by ligation-mediated PCR assay (HELP) uses MspI representations as an internal control [37]. Because MspI is the methylation-insensitive isoschizomer of HpaII, it would cut every possible HpaII restriction site across the genome. By comparing the two profiles generated by each enzyme, Khulan et al. performed both intra- and inter-genomic DNA-methylation analyses in 6.2 Mb of the mouse genome, and identified 223 novel tissue-specific differentially methylated regions [37].
A limitation in utilizing BstUI and HpaII to assess methylation status is that these enzymes identify only a limited fraction of genome CpG sites. To improve sensitivity, Nouzova et al. added a reverse approach by using genomic representations made by digesting with McrBC, an unusual restriction enzyme that cleaves methylated, rather than unmethylated, DNA (Figure 1B). McrBC cuts between two closely spaced (55–100 bp) methylated cytosines in the context (G/A)Cmet, and therefore preferentially digests densely methylated regions of DNA, such as abnormally methylated CGIs in cancer cells and normally methylated repetitive and intragenic sequences in most cells and tissues. As an example of this method, a greater number of hypermethylated loci were identified in an acute promyelocytic leukemia cell line than in normal peripheral blood mononuclear cells, and the sensitivity of the analysis was greater compared with the conventional approach using only HpaII and BstUI [38]. Irizarry et al. developed comprehensive high-throughput arrays for relative methylation (CHARM) from the McrBC assay by improving statistical procedures and the array design algorithm [39]. By using the CHARM assay to detect genome-wide DNA methylation in colon cancers, this group reported hypermethylated CpG sites in 'CGI shores', which were defined as the regions approximately 2 kb away from a CGI [40]. This interesting finding is consistent with the DNA methylation 'spreading theory', which describes that de novo methylation may begin at the flanking CpG sites and progressively invade into the core of the island [41]. As will be described and illustrated in Figure 1B, genomic fractionation into methylated (HpaII-resistant) and unmethylated (McrBC-resistant) fractions can also be exploited for mapping DNA methylation by conventional and NextGen sequencing [5].
Recently, a methodology to enrich the unmethylated DNA with the involvement of multiple enzyme-mediated restrictions was developed [31]. In this approach, genomic DNA was subjected to a cocktail of methylation-sensitive restriction endonucleases (HpaII, Hin6I, AciI, Hin1I and Hpych4IV). This combinatorial approach provides a better coverage (up to 41%) of all CpG dinucleotides in mammalian genomes [31]. After the multiple restrictions of genomic DNA, a double-stranded adaptor was ligated to the CpG overhangs. At this point, the relatively short and amplifiable DNA fragments were predominantly derived from unmethylated regions and were susceptible to the subsequent PCR amplifications. However, if any residual fragments that harbor methylated cytosines remained, they could be further eliminated by a second step of methylation-specific restriction using McrBC prior to the PCR. After the two-step restrictions and subsequent PCR, amplicons were labeled with different fluorescent cyanine (Cy5 or Cy3) dyes for either sample or reference DNA, mixed and cohybridized to oligonucleotide microarrays [31]. In another variation of DMH, enriching unmethylated DNA, the total genomic DNA was first restricted with HpaII, ligated to special linkers prior to subsequent PCR amplifications, and then the resultant amplicons were hybridized to arrays of promoter sequences [42]. This approach relied on the occurrence of two methylation-sensitive restriction sites in close proximity. In this case, if the restriction sites were both unmethylated, they were susceptible to HpaII and could be ligated to linkers followed by PCR amplification. By contrast, if the sites at either or both ends were methylated in the genome then restriction cuts were prevented and longer fragments were generated that were poorly susceptible to PCR amplification.
As DMH methods rely on PCR amplification prior to microarray analysis, Chen et al. conducted a test to determine at which cycles of PCR the amplification is discriminative, and found that PCR should be carried out for less than 29 cycles to prevent overamplification of the partially restricted DNA fragments and yet yield sufficient PCR products for intact DNAs [43]. Besides PCR cycles, another potential bias associated with PCR amplification of GC-rich sequences, including CGIs, is the choice of polymerase enzyme. Pike et al. compared the efficiency of three 'GC-improved' DNA polymerases (AccuPrime™ DNA polymerase [Invitrogen, CA, USA], ThermalAce™ [Invitrogen], DNA polymerase and GC-RICH PCR enzyme [Invitrogen]) to the classical Taq polymerase and found advantages to using these higher efficiency enzymes [44].
Of historical importance, another restriction enzyme-based methodology not involving microarrays is restriction landmark genomic scanning (RLGS), a two-dimensional gel electrophoresis approach combining restriction enzyme polymorphism and DNA methylation-sensitive sites for genome-wide analysis of DNA methylation and expression. This method entails the restriction digestion of genomic DNA with methylation-sensitive restriction enzymes (NotI or AscI) followed by radiolabeling of the restriction fragments and two-dimensional gel electrophoresis; this method yields a pattern of spots on autoradiograms representing unmethylated sites in the genome of the experimental sample being analyzed [45]. Comparison of the patterns of spots found with two different samples has uncovered important differentially methylated genes in diverse cancer types, ranging from leukemias to lung cancers [46–48].
Allele-specific epigenetic modifications are the hallmark of imprinted loci. This type of allelic asymmetry is increasingly recognized as occurring at a subset of nonimprinted loci as well. While simple DMH does not yield information on allele-specific methylation, restriction enzyme-based approaches followed by microarray analysis have now been developed to produce such allele-specific data. In a single nucleotide polymorphism (SNP) chip-based method, called methylation-sensitive SNP chip analysis (MSNP), Yuan et al. and Kerkel et al. used restriction endonuclease-based methylation profiling on Affymetrix SNP arrays to determine net methylation and allele-specific methylation genome-wide [49,50]. In the initial proof-of-principle study using 50K SNP arrays, genomic DNA was first cleaved by XbaI in the presence or absence of HpaII. The resulting DNA fragments were ligated to adaptor linkers, followed by PCR amplification, labeling and hybridization to the SNP arrays, which contain oligonucleotides matching both alleles of a large number of SNPs, distributed at roughly equal intervals along the human genome. The resultant allele-specific SNP hybridization intensities derived from XbaI genomic representations were compared with those from the XbaI/HpaII representation (and control representations with XbaI/MspI). As will be discussed, MSNP can now be applied to 250 K and 1M SNP arrays that use NspI or StyI as the generic restriction enzymes, but the principle remains the same. With regard to DNA methylation, the SNPs on the arrays fall into three general categories. The first is class 1 SNPs, fragments that lack internal HpaII sites, yield genetic information (copy number aberrations and loss of heterozygosity) and serve as invariant internal controls in the DNA methylation analysis. Class 2 SNPs are within fragments that contain HpaII sites at positions other than the SNP itself. In fact, these SNPs are the informative ones for assessing both net (average of the two alleles) and allele-specific DNA methylation. Class 3 SNPs, the rarest category, fall within a CCGG sequence and therefore create or destroy a HpaII restriction site, or have adjacent polymorphic HpaII sites, based on the SNP database. These SNPs are not reliable for assessing DNA methylation but, like the class 1 SNPs, they are useful for assessing loss of heterozygosity and DNA copy number.
In contrast to CGI arrays, SNP arrays and full-genome tiling arrays query diverse locations in the genome that are intergenic, intragenic and promoter CGI-associated. As noted previously, while much prior research in cancer epigenetics has focused on gaining methylation in CGIs, there are advantages to surveying not only islands, but also nonisland sequences. In contrast to islands, the vast majority of which are nonmethylated, nonisland sequences frequently have substantial baseline CpG methylation, so both gains and losses of DNA methylation can be evaluated as biomarkers. Moreover, nonisland CpG sequences may have important regulatory functions that will only be revealed when these sequences begin to be studied using MSNP and related genomic profiling methods such as HELP, CHARM assays and MeDIP on tiling arrays, as well as ultra-high-throughput sequencing.
New biological principles can emerge specifically from studying allele-specific epigenetic modifications by MSNP and related methods. For example, Kerkel et al. carried out a large study of allele-specific methylation in normal human hematopoietic and placental tissues. This study uncovered a strong genetic/epigenetic dependence at multiple loci with strong linkage between SNP genotypes and the propensity of a given allele (CpGs near the SNP) to become methylated [50]. This category of allele-specific methylation, being sequence-dependent, is distinct from genomic imprinting, in which the allele that becomes methylated is determined by its parental origin and not by its sequence. A method very similar to MSNP was utilized to examine allele-specific methylation on the human inactive and active X-chromosomes in females. This study revealed an interesting phenomenon of opposite patterns of methylation in CGIs versus gene bodies (intragenic sequences), such that the CGIs were found to be hypermethylated on the inactive X chromosome while the gene bodies were relatively hypermethylated on the active X chromosome [51].
To characterize methylation patterns at base-pair resolution, bisulfite conversion of DNA followed by sequencing is considered to be the gold-standard approach [52]. Bisulfite conversion-based approaches can be the first step in characterizing DNA methylation both on microarrays and by NextGen sequencing. Bisulfite treatment converts unmethylated cytosines to uracil, such that U is read as T after PCR amplification and sequencing. This conversion does not affect methylated cytosines, which remain C in the sequence. PCR amplicons generated after bisulfite conversion of genomic DNA can be hybridized to microarrays containing methylation-specific oligonucleotides (MSO; comprise 19–23 nucleotides) to query DNA methylation status [53]. As MSO probes discriminated methylated from unmethylated cytosines within a given CG-rich sequence, the quantitative differences in hybridization, which are assessed by the fluorescent intensity, can indicate the methylation status of a particular locus. For example, a set of 12 MSOs was designed to test 15 CpG sites within the CGI in the first exon of the ERα gene [53]. As each probe can interrogate interrogate 2–4 CpG sites in the CGI the methylation status of the ERα gene was identified to be strikingly different among breast cancer cell lines. Likewise, further studies applying MSO were able to classify various human tumor types by methylation patterns [54,55] and classified a specific subtype of non-Hodgkin's lymphoma [56] based on the differential methylation profiles of several gene promoters In addition, a modification of MSO technology illustrating the methylation status of the promoter region of the MGMT gene was developed to examine colorectal cancer [57]. An increasingly popular bisulfite-based high-throughput DNA-methylation profiling platform, commercially available from Illumina, utilizes bead arrays to obtain a quantitative measure of the percentage methylation at each CpG site [58]. In the current version of this approach, genomic DNA samples are bisulfite-converted, and the bead array assay utilizes hybridization and primer extension to query the methylation status of cytosines in specific CpG dinucleotides. The information content of the bead arrays is limited only by the number of specific primers attached to the beads. The proof-of-principle study for this basic approach examined human lung cancers at 1536 specific CpG sites in 371 genes, thereby deriving panels of cancer-specific epigenetic markers [58]. For several years, the coverage offered by this system (Illumina Infinium methylation assays) has increased substantially to more than 20,000 CpGs in promoter regions of more than 14,000 genes.
Genomic fractionation using restriction enzymes has limitations as previously noted. For example, only 3.9% of all CpG dinucleotides in human nonrepetitive regions are recognizable by HpaII [59]. Although the conversion of unmethylated cytosines with bisulfite provides a sensitive alternative, it cannot yet be flexibly or comprehensively applied to whole-genome screenings, as even the Illumina Infinium assays only query a restricted number of CpG sites. A third general type of high-throughput approach in methylation analysis applies MeDIP or affinity chromatography over a methyl-binding domain (MBD) linked to beads, followed by probe preparation and microarray hybridization (Figure 2). MeDIP utilizes nonspecific fragmentation of the genomic DNA followed by anti-5mC antibodies to enrich for methylated DNA fragments. The resultant immunoprecipitated DNA, enriched in hypermethylated sequences, and total genomic DNA (input) are labeled with fluorescent dyes Cy5 and Cy3, respectively, and cohybridized onto microarray chips (Figure 2A). The ratio of fluorescent intensity (Cy5 to Cy3) indicates the methylation status at each particular gene. MeDIP is thus a valuable general fractionation approach, compatible with any genomic microarray platform to query the level of methylation in genomic sequences. In their proof-of-principle study, Weber et al. analyzed the genome-wide methylation between male and female fibroblasts using MeDIP coupled with a comparative genomic hybridization microarray that contains bacterial artificial chromosome clones with an average tiling resolution of 80 kb [24]. In addition to demonstrating methylation differences related to cellular transformation, their results, which included but were not restricted to CGIs, revealed an interesting spatial pattern of methylation on the X chromosome, such that the inactive X chromosome was found to be hypermethylated overall at only a subset of gene-rich regions at the telomeric end and, unexpectedly, was hypomethylated overall relative to its active counterpart. One of the crucial factors in this assay is the sensitivity of the anti-5-methylcytosine antibody. Moreover, the MeDIP method is most sensitive to densely methylated sequences, as DNA fragments with many contiguous methylated CpGs are more efficiently precipitated. Approximately 200 differentially methylated genes were identified in a SW48 colon cancer cell line using MeDIP coupled with a 12k CpG island microarray [24], which were substantially fewer than the previous examination [48]. Keshet et al. coupled MeDIP to a promoter array (nearly 13,000 human gene promoters) and have identified several common motifs of promoters that were significantly methylated in various human cancer cell lines [60].
Unlike conventional MeDIP, which employs a monoclonal antibody against 5-mC in the context of single-stranded DNA, MBD-based affinity purification is an alternative approach to enrich hypermethylated DNA in the genome. An example is methylated CGI recovery assay (MIRA), which utilizes the very high affinity of the MBD2/MBD 3-like 1 complex to purify methylated DNA (Figure 2B). MIRA is not sequence-dependent, and does not require a denaturation step to make the DNA single stranded. MIRA coupled with microarray-based analyses provides high-resolution genome-wide methylation profiling. By this approach, Rauch et al. identified a tumor suppressor gene, DLEC1, as well as 11 homeodomain-family genes that were frequently methylated in primary human lung cancers [61]. It is worth noting that the MIRA approach has now been commercialized by Life Sciences Technologies (Invitrogen). Another laboratory also pursued this affinity approach, in conjunction with a second step of partial strand melting, followed by direct sequencing of the methylated DNA, for successfully identifying methylated CGIs in human lung cancers [62]. A similar strategy, using MBD2 fused to the Fc fragment of human IgG1 by protein A-sepharose, was recently developed [63]. Finally, in an interesting variant of the well known ChIP-on-chip approach for studying chromatin proteins, Ballestar et al. globally examined the distribution of MBD2 as a surrogate marker for densely clustered methylated CpGs in the genome of breast cancer cells [64].
As noted above, in considering the interpretation of microarray experiments using these methods for preparing the probes, it is important to keep in mind that both the MBDs and the anti-5-methyl-C antibody are specifically recognizing only the most densely methylated DNA sequences and are not pulling down DNA that is methylated, even at all available CpGs, in regions of the genome that have a low CpG content. Such regions are better examined by restriction endonuclease-based approaches. It is worthwhile to note that several studies described improved analytic algorithms for interpreting genome-wide methylation data generated by MeDIP experiments [65,66].
Thus, no single approach, with the possible exception of extensive and deep sequencing of bisulfite-converted DNA (which is still slightly beyond current practical capabilities for large sets of biological samples) can give a truly complete picture of the overall epigenome. In summary, combinations of several modalities applied to the same sample set will give the clearest picture.
The availability of NextGen sequencing, that is, a high-throughput sequencing technique, offers much higher coverage per run and relatively lower cost for genome-wide sequencing than previous technologies. Therefore, it provides a more cost-effective platform for large-scale methylation detection. As summarized in Table 1, the most widely used high-throughput sequencing platforms on the market are the 454 Genome sequencer (Roche), Solexa technology (Illumina, CA, USA) and the SOLiD platform (Applied Biosystems Inc., CA, USA). NextGen sequencing technology is in an exponential development stage. Some recent review papers have provided a more comprehensive view of this technology [67,68]. Owing to limited space, a brief introduction to these technologies and their applications in the methylome will be discussed here.
The 454 system was the first platform available for NextGen sequencing. According to the principle of real-time pyrophosphate DNA sequencing method, DNA fragments are ligated to adaptors and subjected to emulsion PCR with water-in-oil microreactors. The sequencing signals are collected through the fluorescence generated from luciferin substrate in the sequencing-by-synthesis (SBS) reaction. The system could conduct more than 1 million individual reads at lengths of up to 500 bp. Illumina developed another high-throughput sequencing platform, Solexa genome analyzer, by using a parallelized sequencing approach. The principle of the analyzer is based on bridge PCR, in which the forward and reverse primers are attached to a solid surface so that the adaptor-ligated DNA fragments can be annealed on the surface and subjected to PCR amplification. The system takes advantage of SBS technology with reversible fluorescently labeled terminators, allowing detection of each single synthesized base in a real-time fashion. Almost 150 million reads could be analyzed within 6 h with an accuracy of 99%. Although up to 75 bp of length could be detected in paired-end sequencing, an average of 36 bp would provide much higher accuracy because of signal decay and dephasing. The third platform, the SOLiD system, is based on a sequencing-by-ligation technique. The system propagates sequencing on the template DNA fragments by ligating a pool of fluorescently labeled octamers that contain random oligonucleotide combinations. Each cycle of hybridization and ligation was proceeded by cleavage of the 3′ end of the ligated octomer and addition of the next fluorescent probe. A total of 400 million sequence tags can be generated per run and the length of each read can reach 50 bp.
By taking advantage of high-throughput sequencing technology, an obvious ultimate objective is to achieve cost-effective complete-genome bisulfite sequencing, which will reveal the methylation status of every CpG dinucleotide. A tour-de-force whole-genome bisulfite sequencing study of Arabidopsis thaliana, a widely used plant genetic model, was recently carried out by the Jacobsen laboratory by using the Solexa platform [69]. Their paper contains an interesting comparison of the relative accuracy of array-based and bisulfite sequencing-based methods and, not surprisingly, the sequencing-based approach was more accurate. Another advantage of the sequencing-based analysis was the ability to score methylation in most types of repetitive sequences, which are less easily probed by microarray-based methods.
Unfortunately, whole-human genome bisulfite sequencing currently remains just out of reach because of the larger genome size and relatively small portion of methylated cytosine in mammalian genomes, compared with Arabidopsis thaliana. Therefore, new approaches have been developed to either enrich high-CpG-density sequences or target specific CpG sites through padlock (molecular inversion) probes. In a pilot study, Taylor et al. used a MDB affinity column to enrich methylated DNA from either normal peripheral blood leukocytes or several types of human lymphomas. The 454 NextGen sequencing platform was used for high-throughput sequencing of bisulfite PCR amplicons [70]. Although this approach circumvents and improves the previously rate-limiting step of cloning the bisulfite PCR products, the total sequencing reads remain less than 1 million. To further extend NextGen sequencing technology to the genome-wide scale, Meissner et al. reported a reduced representation bisulfite sequencing method (Figure 3A), in which 90% of CpG islands in the mouse genome could be covered through MspI fractionation. DNA fragments were then subjected to bisulfite conversion and high-throughput sequencing by the Solexa system [71]. Bestor and associates are utilizing the SOLiD sequencing platform to conduct direct end-sequencing of restriction enzyme-digested and size-fractionated genomic DNA – an approach that they previously validated by using high-volume conventional sequencing [5].
A second approach to selectively sequence the CpG-rich methylome is to target specific CpG sites across the genome. By taking advantage of the pilot study from The Encyclopedia of DNA Elements (ENCODE) project, which provided detailed DNA sequence information for 1% of the human genome [72], two research groups simultaneously reported the utilization of padlock probes to target specific CpG sites across the genome [73,74]. The probes were first synthesized by programmable DNA microarrays based on targeted DNA sequences. As shown in Figure 3B, padlock probes were designed to target both the 5′ and 3′ ends of specific CpG sites in bisulfite-converted DNA, so that the CpG sites fall in the gap between two probes. The methylation status of CpG sites was captured by single-ligation amplification reaction. The beauty of this technique is that the library of tens of thousands of multiplexed padlock probes are amplified in one single tube. The captured targeting CpG sites in padlock loops were then subjected to NextGen sequencing. Although only 66,000 CpG sites, accounting for approximately 0.25% of total CpG sites in human genome, were sequenced in the studies, the assay is ready to expand the representation across genome by following the increasing coverage of the ENCODE project.
New biological generalities are emerging from these studies examining both CGIs and nonisland sequences; for example, Meissner et al. found that most developmental changes in CpG methylation occur outside of promoter regions [71], and Ball et al. found a trend for gene bodies to be hypermethylated as a function of active transcription [73]. Rapid technical progress and new discoveries can be anticipated in this exciting area.
This approach relies on the functional criterion of transcriptional activation to discover genes that have been epigenetically silenced in cancer cells. Demethylating drugs, notably 5-aza-2′-deoxycytidine (5′), can reactivate the expression of genes that have been silenced via promoter hypermethylation by combining 5′ treatment with standard mRNA expression profiling on oligonucleotide or cDNA microarrays. This method is straightforward to generate lists of genes that fit this criterion [75]. The approach is popular and effective; however, its caveats are that it often requires the use of immortalized cell lines, which frequently contain artifactual gains of methylation at many loci [76], and that some of the activated loci might be turning on as an indirect consequence of exposure to the drug and not directly related to methylation of their promoter regions. Thus, after candidate genes are selected from microarray analysis, it is necessary to analyze their methylation patterns in cells before and after treatment by other assays, such as bisulfite sequencing or methylation-specific PCR. Meanwhile, these methylation findings in vitro can be validated in primary tumors.
Methods that can give access to the huge archival collections of well-characterized normal and disease (cancer, other) samples stored in pathology departments of all major medical centers are obviously highly desirable. Furthermore, some key questions, notably defining the epigenetic changes that occur at the earliest stages of tumor initiation, such as in situ carcinomas and dysplasias, can only be addressed in microdissected material, which is often obtained from formalin-fixed paraffin-embedded (FFPE) specimens. The obvious limitations are limited amounts of extractable DNA and substantial degradation of this DNA under the harsh conditions necessary for extracting it from the formaldehyde cross-linked tissues. Nonetheless, restriction digestion/PCR-based protocols have been developed that work well with this material and can be coupled with custom microarrays for medium-throughput applications [77]. Bisulfite conversion/PCR-based protocols are also effective in this setting, as was emphasized in the original report by Herman and coworkers describing the widely used methylation-sensitive PCR (MSP) method [78], and this approach continues to be used in many medium-throughput studies [79,80]. It will be interesting to see how ultra-high-throughput sequencing may open up new vistas in the analysis of DNA methylation in archival FFPE material.
When given a detailed knowledge of the pattern of CpG methylation at a given locus in diseased versus normal tissues, it is generally possible to design methylation-sensitive PCR primers and an internal doubly labeled fluorescent TaqMan® probe (Applied Biosystem Inc.). This possibility allows measurements of the degree of methylation by real-time PCR of bisulfite-converted genomic DNA. This method, which has been validated in several studies by Laird and colleagues, has an experimentally proven sensitivity capable of detecting one methylated DNA molecule in a background of 10,000 unmethylated ones [81,82]. Thus, quantitative MSP, with basic robotics or with multichannel pipetting by hand, is suitable for use in small laboratories both for medium-throughput profiling of a group of candidate genes in a group of experimental samples (~30 genes in ~100 samples) and for diagnostic and screening studies involving the screening of patient samples (blood, urine, sputum and other cytology preparations) for small numbers of tumor cells [83].
Using the mass spectrometry-based platform manufactured by Sequenom (CA, USA), methylation patterns can be unambiguously established quantitatively and at single-base-pair resolution [84]. This medium- to high-throughput approach, which relies on bisulfite conversion followed by PCR amplification of specific loci and site-specific cleavage of an in vitro-transcribed RNA copy of the converted DNA prior to mass spectrometry, has been successfully utilized to profile DNA methylation in human non-small-cell lung cancers [85], as well as breast tumors [86]. It has the advantages of high sample throughput and single-base-pair resolution determination of CpG methylation patterns.
Huang and coworkers have developed a strategy for methylation profiling that reverses the usual approach of hybridizing an array of genes with a probe made from a single experimental sample. Instead, each address on the methylation target arrays (MTA) microarray contains the amplified methylated fraction of the genome from a single sample (tumor, normal, other disease state or tissue). The custom array, containing a large number of experimental samples, is then hybridized with a probe for a specific gene (promoter CGI) or other locus of interest. Based on the hybridization intensity at each address on the array, it is possible to score each sample for the presence or absence of methylation of that sequence. In design, the MTA array is thus analogous to tissue microarrays, which are used to assess immunopositivity for specific protein antigens in large series of human tumors and normal tissues. In the MTA method, the probes to be spotted on the custom microarrays are synthesized by PCR of linker-ligated CGI restriction fragments from the experimental samples of interest that have first been digested with methylation-sensitive restriction enzymes. In their proof-of-principle study, Chen et al. used MTA to determine the frequencies of hypermethylation of a group of ten genes in 93 primary breast cancers [43].
Epigenomic studies have made remarkable progress toward revealing a detailed molecular picture of site-specific DNA methylation in mammalian and plant genomes. Because much of the relevant technology has come from the field of cancer epigenetics, we have given some emphasis to this area here. However, we have also touched on some of the broader applications in other human diseases, and basic biology.
This review discussed the epigenetic and epigenomic technologies used to discover gene silencing in human carcinogenesis. High-throughput analyses can be utilized in at least three ways. First, they provide tools for monitoring the 'cancer-specific' epigenetic markers during cancer early detection and prognosis. In fact, epigenetic therapies are now approved for various hematological malignancies and are currently in clinical trials for solid tumors. The high-throughput epigenetic assessments could be used for evaluating the efficacy of a therapy regimen. Second, these advanced technologies are likely to evolve molecular mechanisms that in part account for tumorigenicity; in this regard, such knowledge can be incorporated to develop new therapeutic strategies. Third, NextGen sequencing technologies are in strong demand for defining human epigenomes at single-base resolution, which cannot be achieved by conventional methods [87,88]. In summary, since most human cancers now appear to be associated with aberrant gene expression in part due to epigenetic alterations, the contribution of high-throughput epigenetic studies cannot be overstated.
This field has seen explosive growth, and although many references are listed here, not every relevant study is cited. Instead, an attempt has been made to cover some of the methods that may be most useful for individual laboratories that are interested in methylation profiling as a tool for asking targeted biological and clinical questions (as summarized in Table 2). A number of companies, not a comprehensive list, are named as manufacturers of platforms and reagents, but this selection is based entirely on references to the corresponding scientific publications and no commercial endorsements are implied.

Berlin: Only an own-goal and a penalty shot got past Gianluigi Buffon at this World Cup. Otherwise, Italy's goalkeeper was unbeatable. "Over the course of a league season there are times when you struggle with your form," Buffon said before Italy beat France 5-3 in a penalty shootout to win its fourth World Cup. "In this tournament, that's never happened and I think that has given my teammates confidence," Buffon added. "It's never crossed my mind that I would be scored on." Italy defender Cristian Zaccardo scored an own-goal 27 minutes into Italy's 1-1 draw with the United States in the first round and Zinedine Zidane converted a penalty for France seven minutes into Sunday's final. In the 103rd minute of the final, Buffon leaped high into the air to push a header from Zidane over the bar. That was about as close as anyone got to scoring on Buffon in normal play over the course of Italy's seven games. Buffon didn't stop any penalties during the shootout - but he didn't have to. That's because Italy converted all five of its shots and David Trezeguet hit his attempt off the crossbar. "It only interests me for the good of the team, not for any personal satisfaction," Buffon said of his performance. While Buffon was superb, Italy's defence deserves just as much merit. "In the end, what has characterised Italy is the group spirit and the absence of egoists," Buffon said. (AP)

Why It Pays to Pay Your Employees to Volunteer
December 19, 2016 | Business and Careers
Nearly every business owner, executive and manager wants to create an environment on the job in which his or her workforce is engaged, productive, loyal and happy. If you can combine that with attracting the best of the best, that's even better for your business. But it's not an easy feat. What's one way you can encourage that? You help them feel good about doing good. You pay them to volunteer.
Employee Volunteer Programs (EVPs) have been shown to motivate and retain top workers and also attract the next generation of leaders, Millennials, who will represent the majority of the workforce in just a few years. A study by the UnitedHealth Group showed that four out of five employees who volunteered through work in the past year feel better about their company because of the employer's involvement in volunteer activities. Clearly there's a movement afoot. But why should your organization consider capitalizing on it?
1. There's good ROI for your organization. Of employees who had volunteered for UnitedHealthcare within the past year, 87 percent reported developing better teamwork and people skills. Some organizations have noticed higher retention rates because workers felt more satisfied and engaged. These improvements are all benefits to a company's bottom line, and workers feel supported in helping out a cause they are passionate about. Other workplace experts continuously find that EVPs increase employee productivity and loyalty. And when your employees are committed to your organization, a Price Waterhouse Coopers study found, they work harder and are 87 percent less likely to resign.
Supporting volunteer work can also build good will for a company's brand. When your company shows that it cares about having an impact in your community, it helps people see your organization in a positive light. That can create ties to new partner organizations or establish connections to future clients.
2. It benefits your employees. There are several ways an employee can benefit from being involved in an EVP. If someone is allowed time to help serve a cause she loves, it can increase a sense of fulfillment at work because your employee feels the company understands and cares about what she cares about. It's also been shown to reduce stress and make people feel healthier. If someone is on a board of directors or leading a team, it can foster new leadership skills and provide a place to test them. Skills-based volunteering can renew passion for what someone does on a daily basis, by offering him a chance to see how old skills can be used in a new way or for a new reason. Finally, volunteering can help your employee find a mentor, someone who leads differently than she does and who can offer to teach her a new skill set.
3. It helps the community. Allowing your staff to engage in an EVP can provide irreplaceable help for nonprofits in your region. Whether you set up an EVP that directs employees to a certain genre of volunteer work or allow them to select a cause they care deeply about, the charities involved are no doubt winners. Here's why:
- Volunteer teams can make a big impact in a small amount of time.
- Skills-based volunteers can provide services nonprofits may not be able to afford on their own.
- Volunteers bring in fresh ideas and new approaches.
- Volunteers can bring in a more operational mindset versus the mission mindset many nonprofits run on.
The idea of paying your employees to volunteer seems counterintuitive, but the more you dig into the benefits of establishing and supporting an EVP, the more you realize it can make good business sense. The charities served benefit, no doubt; but your company will, too. Whether it's through increased employee satisfaction, retention, recruiting or gaining new work-related skills, EVPs are worth every penny of a paycheck you offer an employee to work for someone else.

In an interview with CNSNews.com, Tom Hanks further explained–but stood by his statement–that the Pacific theater of World War II was a war of "racism and terror."
He also said,
"I'd like to think that as our time has gone by and as Americans have found themselves in 2010, ignorance is being replaced by a certain amount of enlightenment and racism is going to be replaced eventually by an acceptance. It's just taking an awfully long time."
A good reply to this has been given by Michael van der Galien:
"I'd like to think," Tom? Is there any doubt in your mind that America has, for the largest part, overcome racism? A black man was voted into the White House, for God's sake. What more proof do you need to understand that racism is, by large, a thing of the past?
What to say about the rest (war of racism and terror, etc.)? Nothing but silence, this time.

Leptin Receptor or CD295 belongs to the gp130 family of cytokine receptors that are known to stimulate gene transcription via activation of cytosolic STAT proteins. This protein is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Leptin Receptor/CD295 is a transmembrane catalytic receptors found on NPY/AgRP and alpha-MSH/CART neurons in hypothalamic nuclei. Leptin receptors (Ob-Rs) are coded for by one human gene that produces six different isoforms; Ob-Ra - Ob-Rf. Ob-Rs exist as constitutive dimers at physiological expression levels. Only the Ob-Rb isoform can transduce intracellular signals and does so through activation of the JAK2/STAT3, PI 3-K and MAPK signaling cascades. Activation of Ob-Rs mediates transcriptional regulation of the hypothalamic melanocortin pathway and downregulates endocannabinoid expression. Leptin acts via leptin receptors. Leptin resistance has been proposed as a pathophysiological mechanism of obesity. In obese individuals, Ob-Ra (which is involved in active transport of leptin across the blood-brain barrier) expression is downregulated and the individual may be unresponsive to leptin signals. Ob-R antagonists are of great interest in the development of pharmacological treatments for obesity. Mutations in Leptin Receptor/CD295 have been associated with obesity and pituitary dysfunction.

They are aware that cricket, which evokes unrivalled passion on both sides of the border, has often been used by governments and political trouble-makers to score points.
Want to show official displeasure? Cancel a bilateral cricket tour. Want your names in the newspapers or news channels? Just vandalise a cricket pitch.
Activists in India and Pakistan have made careers out of staging protests over the game that is worshipped like a religion on the subcontinent.
The upcoming tour will be the mother of all tours, the ultimate rivalry in world cricket that will stop two nations in their tracks when Sachin Tendulkar takes guard against Shoaib Akhtar's thunderbolts.
The long-awaited visit was announced in October just two days after the Indian government lifted a three-year ban on bilateral cricket ties with Pakistan following a thaw in diplomatic relations.
Although the two teams have met in multi-nation events like the World Cup, India has not played a Test in Pakistan since 1989, while Pakistan last crossed the borders in early 1999 for three Test matches.
"The Indian tour will be the best thing to happen to world cricket in recent years," said Ehsan Mani, the Pakistan-born chartered accountant who heads the International Cricket Council (ICC).
Not only will the tour provide succour to the cash-strapped Pakistan Cricket Board (PCB), it will also lend greater credibility and structure to the ICC's 10-year Test calender that has been marred by cancelled tours.
The big bucks have begun to pour in even before the schedule for the March-April tour, comprising three Tests and between five to seven One-day Internationals, has been finalised.
One Indian cricket official predicted a turnover of around 20 million dollars a vast increase from the five-million dollar mark touted for other high-profile series like Australia versus England.
"It is going to be jackpot series, and from my reading of the pulse of the International television rights market, the series is going to be worth 20 million dollars," the official said.
Indo-Pakistan cricket is more than just a game or even commerce. It could boost political relations between the old foes, like the ping-pong diplomacy in 1971 which gave a new fillip to ties between the United States and China.
Former Pakistan president General Zia-ul-Haq tried his own version of the ping-pong diplomacy when he flew to India in 1986 to attend a Test match in Jaipur despite tense relations with the Rajiv Gandhi regime.
It cleared the war clouds hovering near the borders. Cricket ties between India and Pakistan have been both dramatic and rivetting, but they have also swung from the sublime to the ridiculous.
In 1987, Pakistan captain Imran Khan ordered his players to field with helmets on after they were pelted with rubbish during the Ahmedabad Test.
When India toured Pakistan in 1989, its captain Kris Srikkanth was accosted on the field and had his shirt ripped by a spectator during the Karachi Test.
Ten years later, Pakistan beat India in front of empty stands at the 100,000-seater Eden Gardens in Calcutta after crowd violence forced police to clear the galleries.
Yet, the two warring nations joined hands to host two World Cup tournaments in 1987 and 1996 and formed a strong united block at the ICC to break the Australia-England-New Zealand nexus.
During the 1996 World Cup when Australia and the West Indies refused to play in Sri Lanka due to security fears, a joint India-Pakistan team travelled to Colombo for a friendly match to show all was well.
Three years later, a packed Chepauk stadium in Madras gave Wasim Akram's men a heart-warming ovation as they ran a lap of honour after defeating India by 12 runs in the first Test of the 1999 series.
"We play the best cricket against each other," Akram said. "But we should play more against each other so that the tension is less."
If only the politicians and the professional spoilsports can bring themselves to stay away.

By Jorge L. Ortiz, USA TODAY
After losing three of their first four games without Manny Ramirez, the Dodgers still have the best record in baseball.
The Angels don't even lead their division, but they probably wouldn't want to trade places with their Southern California neighbors.
It might be too early to assess the impact Ramirez's 50-game suspension will have on the Dodgers, but at the moment the two Los Angeles teams seem headed in opposite directions.
The Angels, who endured a 9-12 April while trying to overcome the injury absences of starters John Lackey, Ervin Santana and Kelvim Escobar– in addition to the shock of Nick Adenhart's death in a car crash – have bounced back strong in May.
They've won seven of their last eight, defeated the previously unbeaten Zack Greinke and gathered further momentum from Torii Hunter's game-saving catch Sunday as they swept the Royals, holding them to four runs in the three games.
Hunter secured a 4-3 victory when he jumped high above the left-center-field fence to snatch Miguel Olivo's leadoff blast in the ninth, a catch the eight-time Gold Glover ranked among the best of his career.
"When the game ended, Bobby Abreu and Gary Matthews Jr. came over and I was expecting the usual high-fives," Hunter wrote for the Angels website, "but they both threw themselves into me and we had a three-way hug out there. It was just an expression of how great it felt, for all of us."
The Angels climbed above the .500 mark for the first time all season this past weekend, and besides being buoyed by their fine recent play, they expect to get Lackey (strained right forearm) and Santana (strained elbow ligament) back this week.
Their presence should bolster a rotation that has gotten excellent work from Joe Saunders and Jered Weaver, as well as some quality starts from Matt Palmer and Shane Loux.
One will get bumped, as manager Mike Scioscia will enjoy enviable depth.
"When we get to the point of making a decision of what our rotation will be," Scioscia said, "all you can do is make a case to be the guy throwing the ball the best."
While Scioscia ponders how to arrange his enhanced rotation, Dodgers manager Joe Torre must figure out how to handle his team's bruised psyche.
The Dodgers have actually gotten outstanding production in Ramirez's stead from Juan Pierre, who has gone 9-for-16 with two walks, four RBI, four runs scored and two stolen bases since becoming the everyday left fielder.
But the Manny hangover goes far beyond developments on the field. For one, he has yet to address his teammates in person, something team owner Frank McCourt insists Ramirez must do.
Talking to reporters for the first time on the subject Sunday, McCourt said he recently met with Ramirez and the slugger was contrite.
"I found him to be very sorrowful. He was really apologetic. He's very sorry," McCourt said. "He knows he's disappointed not only me but everybody in the front office, Joe (Torre) and everybody in uniform down there, all of his teammates and the fans and the community. He's hurt, but he also knows he dropped the hurt on himself."
The next two weeks should provide an indication of how much his absence will hurt the Dodgers. They averaged nearly six runs in the first four games without Ramirez, but now they embark on a six-game eastern swing, and they'll play their next 12 games against teams that currently have winning marks.
Will they still have the best record in baseball after that stretch?
One-game breakthrough: After scoring a total of five runs in their first two games under new manager A.J. Hinch, both losses, the Diamondbacks doubled that output in Sunday's 10-8 win against the Nationals.
Chris Snyder had a big game with three RBI, but he will lose his status as the everyday catcher under Hinch, who hinted at a platoon with lefty-swinging Miguel Montero.
The Diamondbacks, who gave Hinch a contract through 2012 when he replaced Bob Melvin last Friday, are downplaying his lack of experience running a team – he had not managed at any level before – and stressing his leadership qualities.
In an Arizona Republic profile, people who know Hinch – who turns 35 on Friday – say he has long been mature beyond his years.
Hero of the day: Hunter got up so high in robbing Olivo, "I felt like I could have dunked, two hands, over Shaq. I felt like a wide receiver did a slant up the middle and I was the free safety and I took him out."
Even Hunter's victim had to give him props.
"That (ball) is out. He just took it away," Olivo said. "That's why he's good over there. That's why he's making so much money."
Goat of the day: Starter Nick Blackburn gave the Twins seven shutout innings of five-hit ball against the Mariners, and relievers Jose Mijares and Jesse Crain promptly coughed up the game by allowing a four-run eighth inning by Seattle, which had scored a total of 10 runs in its previous five games.
"Those two guys we count on a lot," Twins manager Ron Gardenhire said. "That's their inning."
On deck: Nationals third baseman Ryan Zimmerman takes his team-record 28-game hitting streak to San Francisco's AT&T Park tonight, when he'll face the Giants' Randy Johnson for the first time. Zimmerman had three hits Sunday and tied Wade Boggs for the longest streak by a third baseman since 1985.
Having their say: "He does that stuff all the time as a pitcher, so I was just having a little fun with him out there."
— Orioles first baseman Aubrey Huff, about his fist-pumps after hitting a three-run homer off the Yankees' demonstrative Joba Chamberlain.
Of note: The Royals put All-Star closer Joakim Soria on the disabled list with a strained rotator cuff. … The Mets rotation is 6-0 with a 2.26 ERA during the team's current seven-game winning streak, and every one of the starters has pitched at least six innings in that span. … The Rockies had lost eight consecutive one-run games before edging the Marlins 3-2. … Tigers starters went 8-4 with a 2.77 ERA in the last 14 games after compiling a 4.64 ERA in their first 16 games. ... The Rangers have gone 9-4 without outfielder Josh Hamilton (sore ribs), who is expected back off the disabled list Tuesday. … The Reds banged out seven homers in the last two games against the Cardinals, who had allowed a major-league-low 11 before their weekend series. … The Phillies have gone 0-10 when scoring less than four runs.
