BET-ting on chromatin-based therapeutics for heart failure

Studies of transcriptional mechanisms in heart failure have focused heavily on roles of sequence-specific DNA-binding factors such as NFAT, MEF2 and GATA4. Recent findings have illuminated crucial functions for epigenetic regulators in the control of cardiac structural remodeling and mechanical dysfunction in response to pathological stress. Here, we review the current understanding of chromatin-dependent signal transduction in cardiac gene control, and highlight the potential for pharmacologic regulation of BET acetyl-lysine binding proteins as a means of treating heart failure.
