Inhibition of histone deacetylases triggers pharmacologic preconditioning effects against myocardial ischemic injury

Abstract: These results suggest that inhibition of HDACs triggers pharmacologic preconditioning to protect the ischemic heart, which involves p38 activation.

“…HDAC4 is expressed in the heart, stem cells, the endothelium, and vascular smooth muscle cells (1,4,12,19,21). Cardioprotective effects of HDAC inhibition against injury have been well identified (45,47,48). Our recent observation demonstrates that HDAC inhibition enhanced myocardial repair in vivo through stimulation of endogenous regeneration (46), which is in line with our observation that HDAC inhibition facilitated the embryonic stem cells' differentiation into cardiac lineages and enhanced resistance to oxidant stress (4).…”

“…Administration of sodium butyrate 24 h prior to and then again 4 h prior to permanent MCAO reduced infarct size by approximately 50 % at 24 h when compared with vehicle-treated controls [33]. This finding suggests that HDAC inhibition may be able to precondition the brain against ischemic damage, as has been demonstrated in the heart using the HDAC inhibitor trichostatin A [35].…”

“…This highlights the need to better understand the pathogenic mechanisms and here we investigate the potential role of aberrant protein acetylation. This appears to be a common feature in proteinopathies (25,29,41,56) and, importantly, drugs to inhibit overactive deacetylation are available and in clinical use.…”

“…HDACs are enzymes that remove acetyl groups from lysine residues on histones and cytoplasmic proteins, but can also affect gene expression, protein function, and cell signaling (28). In the context of cardiac stress, HDAC activity is increased (25,29) and HDAC inhibitors can reduce hypertrophy induced by pressure overload (29,30). Several HDACs, including HDAC6, have been implicated in promoting autophagy and, as such, HDAC inhibitors may also impact on these processes.…”
