abstract = {The stress-responsive epigenetic repressor histone
deacetylase 4 (HDAC4) regulates cardiac gene expression.
Here we show that the levels of an N-terminal
proteolytically derived fragment of HDAC4, termed HDAC4-NT,
are lower in failing mouse hearts than in healthy control
hearts. Virus-mediated transfer of the portion of the Hdac4
gene encoding HDAC4-NT into the mouse myocardium protected
the heart from remodeling and failure; this was associated
with decreased expression of Nr4a1, which encodes a nuclear
orphan receptor, and decreased NR4A1-dependent activation of
the hexosamine biosynthetic pathway (HBP). Conversely,
exercise enhanced HDAC4-NT levels, and mice with a
cardiomyocyte-specific deletion of Hdac4 show reduced
exercise capacity, which was characterized by cardiac
fatigue and increased expression of Nr4a1. Mechanistically,
we found that NR4A1 negatively regulated contractile
function in a manner that depended on the HBP and the
calcium sensor STIM1. Our work describes a new regulatory
axis in which epigenetic regulation of a metabolic pathway
affects calcium handling. Activation of this axis during
intermittent physiological stress promotes cardiac function,
whereas its impairment in sustained pathological cardiac
stress leads to heart failure.},
