Cocktail of eternity: HDAC meets miR.

In this issue of Blood, Sampath and colleagues provide an important missing link in how microRNAs (miRs) can be silenced in chronic lymphocytic leukemia (CLL):histone deacetylases (HDACs) that are overexpressed in CLL block critical miRs in the malignant B cell resulting in pro-survival signals. Thus,HDAC inhibition is an attractive new therapeutic strategy in CLL.
