Activation of Histone Deacetylase-6 Induces Contractile Dysfunction Through Derailment of α-Tubulin Proteostasis in Experimental and Human Atrial Fibrillation

Abstract

AF induces remodeling and loss of contractile function, at least in part through HDAC6 activation and subsequent derailment of α-tubulin proteostasis and disruption of the cardiomyocyte microtubule structure. In vivo inhibition of HDAC6 protects against AF-related atrial remodeling, disclosing the potential of HDAC6 as a therapeutic target in clinical AF.
