摘要

A proteolytic fragment of histone deacetylase 4 protects the heart from failure by regulating the hexosamine biosynthetic pathway A proteolytic fragment of histone deacetylase 4 protects the heart from failure by regulating the hexosamine biosynthetic pathway, Published online: 11 December 2017; doi:10.1038/nm.4452A proteolytically derived fragment of the epigenetic regulator HDAC4 protects the heart through transcriptional repression of the hexosamine biosynthetic pathway, thereby inhibiting protein O-GlcNAcylation and maintaining normal calcium handling and contractility of cardiomyocytes.
