ATF6 protects against protein misfolding during cardiac hypertrophy

Cardiomyocytes activate the unfolded protein response (UPR) transcription factor ATF6 during pressure overload-induced hypertrophic growth. The UPR is thought to increase ER protein folding capacity and maintain proteostasis. ATF6 deficiency during …

Resolving proteotoxicity: Genetic examination of proteasome activation by PKA in vivo

mTORC1 inhibition impairs activation of the unfolded protein response and induces cell death during ER stress in cardiomyocytes

The mechanistic target of rapamycin complex 1 (mTORC1) is a central regulator of protein synthesis that senses and responds to a variety of stimuli to coordinate cellular metabolism with environmental conditions. To ensure that protein synthesis is …

IRE1/XBP1 and Endoplasmic Reticulum Signaling--From Basic to Translational Research for Cardiovascular Disease

VARS2 depletion leads to activation of the integrated stress response and disruptions in mitochondrial fatty acid oxidation

Identification of dynamic RNA-binding proteins uncovers a Cpeb4-controlled regulatory cascade during pathological cell growth of cardiomyocytes

RNA-binding proteins (RBPs) control critical aspects of cardiomyocyte function, but the repertoire of active RBPs in cardiomyocytes during the growth response is largely unknown. We define RBPs in healthy and diseased cardiomyocytes at a system-wide …

Muscle-specific Cand2 is translationally upregulated by mTORC1 and promotes adverse cardiac remodeling

A multi-network comparative analysis of transcriptome and translatome identifies novel hub genes in cardiac remodeling

Our understanding of the transition from physiological to pathological cardiac hypertrophy remains elusive and largely based on reductionist hypotheses. Here, we profiled the translatomes of 15 mouse hearts to provide a molecular blueprint of altered …

ER stress-induced secretion of proteins and their extracellular functions in the heart

Endoplasmic reticulum (ER) stress is a result of conditions that imbalance protein homeostasis or proteostasis at the ER, for example ischemia, and is a common event in various human pathologies, including the diseased heart. Cardiac integrity and …
