Mesencephalic astrocyte-derived neurotrophic factor protects the heart from ischemic damage and is selectively secreted upon sarco/endoplasmic reticulum calcium depletion.

The endoplasmic reticulum (ER) stress protein mesencephalic astrocyte-derived neurotrophic factor (MANF) has been reported to protect cells from stress-induced cell death before and after its secretion; however, the conditions under which it is …

Regulation of microRNA expression in the heart by the ATF6 branch of the ER stress response.

A nodal regulator of endoplasmic reticulum stress is the transcription factor, ATF6, which is activated by ischemia and protects the heart from ischemic damage, in vivo. To explore mechanisms of ATF6-mediated protection in the heart, a whole-genome …

The cardiokine story unfolds: ischemic stress-induced protein secretion in the heart.

Intercellular communication depends on many factors, including proteins released via the classical or non-classical secretory pathways, many of which must be properly folded to be functional. Owing to their adverse effects on the secretion machinery, …

Effects of the isoform-specific characteristics of ATF6 alpha and ATF6 beta on endoplasmic reticulum stress response gene expression and cell viability.

The endoplasmic reticulum (ER)-transmembrane proteins, ATF6 alpha and ATF6 beta, are cleaved during the ER stress response (ERSR). The resulting N-terminal fragments (N-ATF6 alpha and N-ATF6 beta) have conserved DNA-binding domains and divergent …

Activation of p38 has opposing effects on the proliferation and migration of endothelial cells.

Pathological conditions such as hypertension and hyperglycemia as well as abrasions following balloon angioplasty all lead to endothelial dysfunction that impacts disease morbidity. These conditions are associated with the elaboration of a variety of …
