Expression and purification of cytokine receptor homology domain of human granulocyte-colony-stimulating factor receptor fusion protein in Escherichia coli . Direct expression of the cytokine receptor homology ( P06850 ) domain of granulocyte-colony-stimulating factor ( DB00099 ) receptor is lethal to Escherichia coli . For the efficient and stable production of an active P06850 domain in E. coli , we fused the P06850 domain with different proteins , such as maltose-binding protein ( MalE ) , glutathione S-transferase , and thioredoxin ( P10599 ) . Among these , P10599 appeared to be the best in terms of the protein expression level , purification efficiency by affinity chromatography , and binding activity to its ligand , DB00099 . The yield of active P10599 - P06850 fusion protein increased about 200-fold compared to that of previously reported MalE- P06850 fusion . DB05767 ( Andrographis paniculata extract ) prevents development of murine colitis by inhibiting T-cell proliferation and Q8IXH7 /TH17 responses . BACKGROUND : Extracts of the plant Andrographis paniculata have been used to treat inflammatory diseases in Asian countries . A recent double-blind , placebo-controlled trial of DB05767 ( A. paniculata extract ) has demonstrated its safety and effectiveness for induction of clinical response , remission , and mucosal healing in patients with mild to moderate ulcerative colitis ( UC ) . We aimed to determine if DB05767 could prevent the development of T-cell-dependent murine colitis and to define its in vivo mechanism(s) of action . METHODS : CD(+)4CD45RB(high) T cells were transferred into Rag1(-/-) mice and gavaged daily with DB05767 or methyl cellulose ( MC ) . Severity of colitis was evaluated by weight loss , histology , and cytokine expression . RESULTS : Mice treated with MC developed colitis within 4-7 weeks , as evaluated by weight loss , and severe intestinal inflammation . DB05767 -treated mice did not lose weight and displayed only very mild intestinal inflammation . P01375 alpha ( P01375 -α ) , interleukin ( IL ) -1β , interferon-gamma ( IFN-γ ) , and Q9GZX6 expression were significantly decreased in DB05767 -treated mice . We observed higher percentages of naïve P01730 (+) T cells in the lamina propria of DB05767 -treated mice . At early timepoints DB05767 -treated mice have significantly reduced splenic cell counts , reduced P01730 (+) , and Q16552 (+) , and IFN-γ T(+) cells . Furthermore , DB05767 inhibited the proliferation of P01730 T cells and differentiation into Q8IXH7 /TH17 cells in vitro . CONCLUSIONS : DB05767 inhibits the development of chronic colitis by affecting early T-cell proliferation , differentiation , and TH(1)/TH(17) responses in a T-cell-driven model of colitis , presenting a unique mechanism of action . Our data suggest that DB05767 could be an attractive herbal therapeutic for inflammatory bowel disease . DB00104 prevents growth factor-induced proliferation of bovine retinal endothelial cells under hypoxia . Ocular diseases such as proliferative diabetic retinopathy are the major cause of blindness in industrialized countries . The main pathologic features of these diseases are hypoxia and overproduction of growth factors resulting in pathologic proliferation of endothelial cells and new vessel formation . Particularly , hypoxia and growth factors , such as P15692 , DB01277 , P09038 and TGF beta(2) , show a complex interaction in the onset and progression of the diseases . Therefore , to date , most therapeutic strategies for proliferative retinopathies have targeted proliferation of endothelial cells evoked by growth factors . Recently , a synthetic analog of somatostatin , octreotide , has been shown to inhibit the proliferation of various cells in vitro , including endothelial cells . In this study , we have investigated the proliferative response of bovine retinal endothelial cells ( BREC ) to growth factors under hypoxic conditions and the modulation by octreotide . We found a dose-dependent increase of cell proliferation with P15692 , DB01277 and P09038 , and inhibition of hypoxia-induced cell proliferation with TGF beta(2) . Moreover , growth factor-induced , but not hypoxia-induced , cell proliferation was attenuated in the presence of octreotide . In contrast , TGF beta(2) abolished hypoxia-induced BREC proliferation . Similar to octreotide BIM23027 , a somatastatin receptor subtype 2 ( P30874 ) receptor agonist was able to attenuate the growth factor-induced proliferation of BREC expressing mRNA and protein for P30874 . Therefore , we postulate that octreotide exerts its effects mainly through binding to the P30874 . Taken together , our findings point to octreotide as a promising candidate for the treatment of eye disorders involving growth factor-dependent proliferation of endothelial cells . Blockade of corticotropin-releasing hormone receptor 1 attenuates early-life stress-induced synaptic abnormalities in the neonatal hippocampus . Adult individuals with early stressful experience exhibit impaired hippocampal neuronal morphology , synaptic plasticity and cognitive performance . While our knowledge on the persistent effects of early-life stress on hippocampal structure and function and the underlying mechanisms has advanced over the recent years , the molecular basis of the immediate postnatal stress effects on hippocampal development remains to be investigated . Here , we reported that repeated blockade of corticotropin-releasing hormone receptor 1 ( P34998 ) ameliorated postnatal stress-induced hippocampal synaptic abnormalities in neonatal mice . Following the stress exposure , pups with fragmented maternal care showed retarded dendritic outgrowth and spine formation in P07451 pyramidal neurons and reduced hippocampal levels of synapse-related proteins . During the stress exposure , repeated blockade of glucocorticoid receptors ( GRs ) by daily administration of DB00834 ( 100 µg g(-1) ) failed to attenuate postnatal stress-evoked synaptic impairments . Conversely , daily administration of the P34998 antagonist antalarmin hydrochloride ( 20 µg g(-1) ) in stressed pups normalized hippocampal protein levels of synaptophysin , postsynaptic density-95 , nectin-1 , and nectin-3 , but not the N-methyl-d-aspartate receptor subunits Q9UHB4 and Q12879 . Additionally , GR or P34998 antagonism attenuated postnatal stress-induced endocrine alterations but not body growth retardation . Our data indicate that the P06850 - P34998 system modulates the deleterious effects of early-life stress on dendritic development , spinogenesis , and synapse formation , and that early interventions of this system may prevent stress-induced hippocampal maldevelopment . DB00104 and the novel multireceptor ligand somatostatin receptor agonist pasireotide ( DB06663 ) block the adrenalectomy-induced increase in mitotic activity in male rat anterior pituitary . The novel somatostatin receptor agonist pasireotide binds with high affinity to somatostatin receptors P30872 , 2 , 3 , and 5 . Acting principally through the latter , it inhibits basal and P06850 -stimulated DB01285 secretion from the AtT20 corticotroph cell line and DB01285 release from a proportion of human corticotroph adenomas both in vitro and in vivo . Data supporting an additional antiproliferative effect has led to pasireotide being explored as a potential therapy for patients with Cushing 's disease . We have compared the effects of pasireotide and octreotide on adrenalectomy-induced mitotic and apoptotic activity in the male rat anterior pituitary . Adrenalectomized rats were treated with daily sc injections of vehicle , pasireotide , or octreotide . Changes in proliferation and apoptosis were determined 2-6 d postoperatively . DB06663 and octreotide had no effect on baseline pituitary cell turnover and no measurable effects on apoptosis . However , the wave of increased mitotic activity normally seen in the pituitary after adrenalectomy was completely abolished . Nevertheless , pasireotide and octreotide did not diminish the increase in DB01285 -immunopositive cell index after adrenalectomy , indicating that cell division and differentiation of hormonally null cells in the pituitary are under independent control . In conclusion , basal cell turnover in the pituitary is not inhibited by pasireotide or octreotide . Bilateral adrenalectomy stimulates differentiation of preexisting null cells into DB01285 -positive cells . Cell division after bilateral adrenalectomy occurs in a specific subpopulation of hormonally null cells that are equally sensitive to the antiproliferative effects of pasireotide and octreotide , implicating P30874 receptors in this antimitotic response . Functional identification of NR2 subunits contributing to DB01221 receptors on DB05875 receptor-expressing dorsal horn neurons . DB01221 receptors are important elements in pain signaling in the spinal cord dorsal horn . They are heterotetramers typically composed of two Q9UHB4 and two of four NR2 subunits : Q12879 -2D . Mice lacking specific NR2 subunits show deficits in pain transmission yet subunit location in the spinal cord remains unclear . We have combined electrophysiological and pharmacological approaches to investigate the composition of functional DB01221 receptors expressed by lamina I , DB05875 receptor-expressing ( P25103 + ) neurons , as well as P25103 - neurons . Under low Mg2+ conditions ( 100 microM ) , the conductance of DB01221 receptors at -90 mV ( g ( -90 mV ) ) with Q12879 or Q13224 subunits ( Q12879 /B ) is low compared to conductance measured at the membrane potential where the inward current is maximal or maximal inward current ( MIC ) ( ratio of approximately 0.07 calculated from Kuner and Schoepfer , 1996 ) . For Q14957 or O15399 subunits ( Q14957 /D ) , the ratio is higher ( ratio approximately 0.4 ) . P25103 + and P25103 - neurons express DB01221 receptors that give ratios approximately 0.28 and 0.16 , respectively , suggesting both types of subunits are present in both populations of neurons , with P25103 + neurons expressing a higher percentage of Q14957 /D type DB01221 receptors . This was confirmed using EAB318 , an Q12879 /B preferring antagonist , and UBP141 , a mildly selective Q14957 /D antagonist to increase and decrease the g ( -90 mV ) /g(MIC) ratios in both subpopulations of neurons . P06850 and acute stress prolongs serotonergic regulation of GABA transmission in prefrontal cortical pyramidal neurons . The stress-related neuropeptide DB05394 ( CRF ) and the serotonin system are both critically involved in the pathophysiology of mental disorders , including anxiety and depression . To understand the potential link between them , we investigated the impact of CRF on 5-HT functions in pyramidal neurons of the prefrontal cortex ( P27918 ) , a brain region that is crucial for the control of emotion and cognition . One prominent function of serotonin in P27918 is to regulate GABAergic inhibitory transmission , as indicated by a 5-HT-induced large , desensitizing ( approximately 4 min ) enhancement of the amplitude and frequency of spontaneous IPSCs ( sIPSCs ) . In P27918 slices exposed to CRF treatment , the regulation of sIPSCs by 5-HT was significantly prolonged ( 8-10 min ) , and this effect of CRF was blocked by treatment with the competitive CRF receptor antagonist alpha-helical CRF9-41 and with the P34998 -specific antagonist astressin . Inhibiting phospholipase C or protein kinase C ( PKC ) abolished the prolongation by CRF of the effects of 5-HT on sIPSCs . In P27918 slices prepared from animals previously exposed to acute stress ( forced swim or elevated platform ) , the regulation of sIPSCs by 5-HT was significantly prolonged , mimicking the effect of CRF treatment . The stress-induced prolongation of the effects of 5-HT on sIPSCs was diminished by alpha-helical CRF9-41 treatment , mimicked by direct activation of PKC , and reversed by short-term treatment with drugs that have anxiolytic efficacy . These results show that in response to stressful stimuli , CRF alters the serotonergic regulation of GABA transmission through a mechanism that is dependent on PKC . The interaction between CRF and 5-HT may play an important role in psychiatric disorders , in which both are highly implicated . Influenza H1N1 infection in a patient with psoriatic arthritis in treatment with DB00051 : a case report . In March 2009 was the beginning of an epidemic flue caused by avian influenza A virus H1N1 . The disease varies from mild to serious and fatal cases . There are many hypotheses explaining why this virus infection would be fatal . One of these is the impaired immune response of the infected patient . The use of tumor necrosis factor-alpha inhibitors may cause decreased immune response and greater susceptibility to infections . We presented a case of a patient using adalimumab that have developed H1N1 without complications . This is the first case of H1N1 in a patient using adalimumab reported in Brazil . We discuss the possibility that anti- P01375 may not predisposes to a serious form of the disease or fatal complications . Epigenetic variation during the adult lifespan : cross-sectional and longitudinal data on monozygotic twin pairs . The accumulation of epigenetic changes was proposed to contribute to the age-related increase in the risk of most common diseases . In this study on 230 monozygotic twin pairs ( MZ pairs ) , aged 18-89 years , we investigated the occurrence of epigenetic changes over the adult lifespan . Using mass spectrometry , we investigated variation in global ( LINE1 ) DNA methylation and in DNA methylation at P01308 , KCNQ1OT1 , P01344 , GNASAS , O95477 , P41159 , and P06850 , candidate loci for common diseases . Except for KCNQ1OT1 , interindividual variation in locus-specific DNA methylation was larger in old individuals than in young individuals , ranging from 1.2-fold larger at O95477 ( P = 0.010 ) to 1.6-fold larger at P01308 ( P = 3.7 × 10(-07) ) . Similarly , there was more within-MZ-pair discordance in old as compared with young MZ pairs , except for GNASAS , ranging from an 8 % increase in discordance each decade at P06850 ( P = 8.9 × 10(-06) ) to a 16 % increase each decade at P41159 ( P = 2.0 × 10(-08) ) . Still , old MZ pairs with strikingly similar DNA methylation were also observed at these loci . After 10-year follow-up in elderly twins , the variation in DNA methylation showed a similar pattern of change as observed cross-sectionally . The age-related increase in methylation variation was generally attributable to unique environmental factors , except for P06850 , for which familial factors may play a more important role . In conclusion , sustained epigenetic differences arise from early adulthood to old age and contribute to an increasing discordance of MZ twins during aging . Con A-propagated , auto-reactive T cell clones that secrete factors promoting high IgA responses . Four BALB/c T cell clones from among a set propagated in the presence of concanavalin A ( Con A ) were selected on the basis of their ability to produce supernatant factors promoting high IgA plaque-forming cell ( P27918 ) responses by 2,4,6-trinitrophenyl-conjugated DB05299 ( TNP-KLH ) -primed splenic B cells in the presence of TNP-SRBC . Such clones could be derived from cultures containing T cells not only from gut-associated lymphoid tissue , but also from the spleen . The selected clones all proliferated well in the presence of syngeneic , irradiated P25054 without either Con A or exogenous P60568 , but required both P25054 and Con A to produce helper factors . Factors from three of the clones helped B cells both to proliferate and to differentiate into IgM , IgG and IgA P27918 . Factors from the fourth clone helped B cells differentiate into IgA and IgG P27918 and may have promoted switching to these isotypes but did not support either B cell proliferation or generation of IgM P27918 . Cross-linking of B cell receptors for antigen was not required for the response to the helper factors since TNP-SRBC were unnecessary and high concentrations of them were actually inhibitory . DB00644 II ( DB00644 II ) mediates the anorexigenic actions of α-melanocyte-stimulating hormone ( α-MSH ) and corticotropin-releasing hormone ( P06850 ) in goldfish . Intracerebroventricular ( ICV ) administration of gonadotropin-releasing hormone II ( DB00644 II ) , which plays a crucial role in the regulation of reproduction in vertebrates , markedly reduces food intake in goldfish . However , the neurochemical pathways involved in the anorexigenic action of DB00644 II and its interaction with other neuropeptides have not yet been identified . Alpha-melanocyte-stimulating hormone ( α-MSH ) , corticotropin-releasing hormone ( P06850 ) and P06850 -related peptides play a major role in feeding control as potent anorexigenic neuropeptides in goldfish . However , our previous study has indicated that the DB00644 II-induced anorexigenic action is not blocked by treatment with melanocortin 4 receptor ( P32245 ) and P06850 receptor antagonists . Therefore , in the present study , we further examined whether the anorexigenic effects of α-MSH and P06850 in goldfish could be mediated through the P30968 neuronal pathway . ICV injection of the P32245 agonist , melanotan II ( 80 pmol/g body weight ; BW ) , significantly reduced food intake , and its anorexigenic effect was suppressed by ICV pre-administration of the DB00644 type I receptor antagonist , antide ( 100 pmol/gBW ) . The P06850 -induced ( 50 pmol/gBW ) anorexigenic action was also blocked by treatment with antide . ICV injection of P06850 ( 50 pmol/gBW ) induced a significant increase of the DB00644 II mRNA level in the hypothalamus , while ICV injection of melanotan II ( 80 pmol/gBW ) had no effect on the level of DB00644 II mRNA . These results indicate that , in goldfish , the anorexigenic actions of α-MSH and P06850 are mediated through the DB00644 type I receptor-signaling pathway , and that the DB00644 II system regulates feeding behavior . DB08865 for the treatment of patients with advanced non-small cell lung cancer . DB08865 is a potent small-molecule inhibitor of Q9UM73 ( anaplastic lymphoma kinase ; Q9UM73 ) and hepatocyte growth factor receptor ( P08581 , proto-oncogene c- DB00134 ) . A range of tumors , including subsets of non-small cell lung cancer ( NSCLC ) , anaplastic large cell lymphoma and inflammatory myofibroblastic tumors harbor an Q9UM73 rearrangement that leads to oncogenic activation of Q9UM73 . DB08865 has demonstrated preclinical and clinical activity against such malignancies through inhibition of Q9UM73 , and patients harboring Q9UM73 - rearranged NSCLC have demonstrated high response rates and prolonged progression-free survival in phase I and II studies . In August 2011 , crizotinib was approved for the treatment of advanced Q9UM73 -positive NSCLC . Discovery of selective Q07343 inhibitors . In this study the first Q07343 selective inhibitor is described . Optimization of lead 2-arylpyrimidine derivatives afforded a series of potent Q07343 inhibitors with > 100-fold selectivity over the Q08499 isozyme . With a good pharmacokinetic profile , a selected compound exhibited potent anti-inflammatory effects in vivo and showed less emesis compared with DB03849 . Relative contributions of O95477 and Q8WTV0 to cholesterol efflux to serum from fibroblasts and macrophages . OBJECTIVE : DB04540 efflux is achieved by several mechanisms . This study examines contributions of these pathways to efflux to human serum . METHODS AND RESULTS : Human fibroblasts were stably transfected with Q8WTV0 while O95477 was upregulated . Quantitation of cholesterol efflux to human serum demonstrated that there was efflux from cells without either protein . Expression of O95477 produced a small increase in efflux , whereas Q8WTV0 expression had a dramatic impact . To quantitate O95477 and Q8WTV0 contribution , fibroblasts were pretreated with DB01599 and Q15722 -1 to , respectively , inhibit these efflux proteins . Exposing Q8WTV0 -expressing fibroblasts to Q15722 -1 inhibited efflux by 67 % . DB01599 pretreatment of O95477 -expressing fibroblasts reduced efflux to serum by 26 % . A large fraction of total efflux was uninhibited . For both J774 and mouse peritoneal macrophages , contributions of either O95477 or Q8WTV0 to efflux to serum were low , with background/uninhibited efflux contributing from 70 % to 90 % of total efflux . CONCLUSIONS : We have shown that O95477 -mediated efflux to serum responds to the pool of lipid-free/poor apolipoproteins , whereas phospholipid-containing particles mediate Q8WTV0 efflux . Although Q8WTV0 and O95477 contribute to efflux from fibroblasts and cholesterol-enriched macrophages , a large proportion of the total efflux to human serum is mediated by a mechanism that is neither Q8WTV0 nor O95477 . Sexually dimorphic stress and pro-inflammatory cytokine responses to an intravenous corticotropin-releasing hormone challenge of Brahman cattle following transportation . This study was designed to characterize potential sexually dimorphic stress and immunological responses following a corticotropin-releasing hormone ( P06850 ) challenge in beef cattle . Six female ( heifers ) and six male ( bulls ) Brahman calves ( 264 ± 12 d of age ) were administered P06850 intravenously ( 0.5 µg of P06850 /kg body mass ) after which serum concentrations of cortisol increased from 0.5 h to 4 h . From 1 h to 4 h after P06850 administration , serum cortisol concentrations were greater in heifers than in bulls . In all cattle , increased serum concentrations of P01375 -α , P05231 and IFN-γ were observed from 2.5 h to 3 h after P06850 , with greater concentrations of IFN-γ and P05231 in heifers than bulls . Heifer total leukocyte counts decreased 1 h after P06850 administration , while bull leukocyte counts and percent neutrophils decreased 2 h after P06850 administration . Heifers had greater rectal temperatures than bulls , yet rectal temperatures did not change following administration of P06850 . There was no effect of P06850 administration on heart rate . However , bulls tended to have increased heart rate 2 h after P06850 administration than before P06850 . Heifer heart rate was greater than bulls throughout the study . These data demonstrate that acute P06850 administration can elicit a pro-inflammatory response , and cattle exhibit a sexually dimorphic pro-inflammatory cytokine and cortisol response to acute P06850 administration . DB00104 -targeted liposomes loaded with CPT-11 enhanced cytotoxicity for the treatment of medullary thyroid carcinoma . Medullary thyroid carcinoma ( P04629 ) is a rare endocrine tumor that frequently metastasizes , but treatment with irinotecan ( CPT-11 ) is limited because of side effects . P04629 is known to overexpress the somatostatin receptor subtype 2 ( P30874 ) . DB00104 ( Oct ) is a somatostatin analogue that has a high binding affinity for SSTR and can be used as a tumor-targeting ligand . We prepared Oct-targeted liposomes loaded with CPT-11 using Oct-poly ( ethylene glycol ) ( PEG ) -lipid and evaluated Oct-mediated association and cytotoxicity of the liposomes with an P04629 cell line TT . The association of higher concentrations of modified Oct-targeted liposomes with TT cells was significantly higher than PEGylated liposomes and was significantly inhibited by empty Oct-targeted liposomes but not by free Oct . With exposure for 96 h , the cytotoxicity of Oct-targeted liposomal CPT-11 ( IC50 : 1.05 ± 0.47 μM ) was higher than free CPT-11 ( IC50 : 3.76 ± 0.61 μM ) or PEGylated liposomal CPT-11 ( IC50 : 3.05 ± 0.28 μM ) . In addition , empty Oct-targeted liposomes showed significantly higher cytotoxicity than empty nontargeted liposomes at a concentration where free Oct did not show cytotoxicity , suggesting that Oct as a ligand showed cytotoxicity . Moreover , Oct-targeted liposomal CPT-11 led to significantly higher antitumor activity and prolonged the survival time compared with nontargeted liposomal and free CPT-11 at a one-third dose and lower administration times with free CPT-11 . These findings indicated that Oct-targeted liposomes loaded with CPT-11 may offer considerable potential for P04629 chemotherapy because cytotoxicity of both CPT-11 and Oct was enhanced by effective cellular uptake via P30874 . A novel multiple tyrosine-kinase targeted agent to explore the future perspectives of anti-angiogenic therapy for the treatment of multiple solid tumors : cabozantinib . The process of angiogenesis involves the formation of new blood vessels from pre-existing vasculature by the over expression of certain factors leading to the growth and development of all solid tumor types . P08581 abbreviated as c- DB00134 and vascular endothelial growth factor abbreviated as P15692 are some of the factors responsible for the induction in tumor growth and development . Recently a number of analogues associated with these receptors are under study . US FDA on November 29 , 2012 approved a drug named cabozantinib formerly known as DB05153 which is being marketed under the trade name of Cometriq for the treatment of Medullary Thyroid Cancer ( P04629 ) . Designing of the drug has been done in such a fashion that it can inhibit both P35968 and c- DB00134 simultaneously without over expressing any of the factors leading to the inhibition of angiogenesis . The drug is still under study for the evaluation of its efficacy in cases of many other solid tumor types including breast cancer , castration resistant prostate cancer ( CRPC ) , renal cell carcinoma ( RCC ) , hepatocellular carcinoma ( HCC ) , gastric or gastroesophageal junction cancer , melanoma , small cell lung cancer ( SCLC ) , ovarian cancer and primary peritoneal or fallopian tube carcinoma . This review article consists of preclinical and clinical data of cabozantinib and its efficacy and safety towards various types of solid tumors . The differential impact of DB05876 subtypes in human lung fibroblasts on cytokine-induced proliferation and myofibroblast conversion . Lung fibroblast proliferation and differentiation into myofibroblasts are pathological key events during development of lung fibrosis . Cyclic nucleotide signaling is described as a negative modulator of these cellular processes , and cyclic nucleotide degrading type 4 phosphodiesterases ( DB05876 ) are important regulators of these pathways . In this study , we elucidated expression and the role of individual subtypes of DB05876 in primary normal human lung fibroblast ( NHLF ) in controlling cytokines-induced proliferation and conversion to myofibroblasts by short-interfering RNAs ( siRNAs ) induced knockdown . We verified the expression of P27815 , B , and D , while Q08493 was only minor or even not expressed in NHLF . An efficient liposome-mediated transfection method for mRNA silencing and a knockdown of the expressed DB05876 subtypes was achieved in these cells . This knockdown was further validated by DB05876 protein expression analysis and DB05876 activity measurements . Functionally , the knockdown of P27815 and Q07343 inhibited proliferation induced by the cytokine combination of P09038 and IL-1β , whereas knockdown of Q08499 was ineffective . In contrast , TGF-β induced differentiation into myofibroblasts was affected by knockdown of Q07343 and Q08499 , but not by P27815 knockdown . In summary , our data allow to assign different DB05876 subtypes to distinct functions of human lung fibroblasts and highlight the predominant role of Q07343 in controlling pathophysiological processes of human lung fibroblasts . This provides a scientific rationale for focused therapeutic targeting of Q07343 to treat respiratory diseases with fibrotic lesions in the lung . [ DB08836 treatment upregulated cardiomyocyte thioredoxin expression and improved autoimmune myocarditis ] . OBJECTIVE : P10599 ( TRX ) is a redox regulatory protein that protects cells from various stresses . P12821 ( P12821 ) inhibitor was reported to enhance endogenous antioxidant enzyme activities . This study was carried out to investigate whether temocapril , a novel non-sulfhydryl containing P12821 inhibitor , reduces the severity of myocarditis via redox regulation mechanisms involving TRX . METHODS : The up-regulation of TRX by temocapril treatment was checked by Western blot in normal rat myocytes in vitro and in vivo , as well as in rats with experimental autoimmune myocarditis ( EAM ) . RESULTS : DB08836 enhanced cytosolic redox regulatory protein TRX expression , but neither mitochondrial TRX2 nor antioxidant enzymes , such as copper-zinc superoxide dismutase ( Cu/Zn-SOD ) or manganese superoxide dismutase ( Mn-SOD ) expression , was up-regulated by the preconditioning treatment . In rats with EAM , the severity of myocarditis and the protein carbonyl contents were less increased in temocapril treatment ( 10 mg x kg(-1) x d(-1) , orally ) from day 1 to day 21 , but not in temocapril treatment from day 15 to day 21 . If the characteristics of this model that myocardial inflammation begins around day 15 and keeps on until day 21 is considered , temocapril treatment for 3 weeks might be thought as a preconditioning treatment . CONCLUSIONS : TRX and the redox state modified by TRX may play a crucial role in the pathophysiology of EAM . DB08836 ameliorates myocarditis with inducing TRX up-regulation in a preconditioning manner , although the mechanism of TRX up-regulation by temocapril remains to be elucidated . Effects of gonadoliberin analogue triptorelin on the pituitary-testicular complex in neonatal rats . DB06825 , a synthetic analogue of neurohormone gonadoliberin ( gonadotropin-releasing hormone , DB00644 ) administered daily to rats on postnatal days 5-7 suppressed the expression of P30968 in the pituitary gland , but did not change functioning of the pituitary-testicular complex . Administration of triptorelin on postnatal days 12-14 ( i.e. during the formation of pulsatile pattern of DB00644 secretion and increasing levels of its mRNA receptor in the pituitary gland ) had no effect on receptor expression , but increased the levels of luteinizing hormone mRNA in the pituitary gland and the weight of testes . At that time , blood levels of testosterone were lowered , which indicated disturbed pulsatile pattern of DB00644 secretion .
