Unfolding the Roles of Mitochondria as Therapeutic Targets for Heart Disease.

Expanding the Paracrine Hypothesis of Stem Cell-Mediated Repair in the Heart: When the Unconventional Becomes Conventional.

Recent interest in mechanisms of stem cell-mediated repair in the heart have spawned the ``paracrine hypothesis'', which posits that stem cells release beneficial substances that improve regeneration and function of the injured and diseased …

CaMKIIδ subtypes differentially regulate infarct formation following ex vivo myocardial ischemia/reperfusion through NF-κB and TNF-α.

Deletion of Ca(2+)/calmodulin-dependent protein kinase II delta (CaMKIIδ) has been shown to protect against in vivo ischemia/reperfusion (I/R) injury. It remains unclear which CaMKIIδ isoforms and downstream mechanisms are responsible for the …

Roles for ATF6 and the sarco/endoplasmic reticulum protein quality control system in the heart.

The hypertrophic growth of cardiac myocytes is a highly dynamic process that underlies physiological and pathological adaptation of the heart. Accordingly, a better understanding of the molecular underpinnings of cardiac myocyte hypertrophy is …

New concepts of endoplasmic reticulum function in the heart: programmed to conserve.

Secreted and membrane proteins play critical roles in myocardial health and disease. Studies in non-myocytes have shown that the peri-nuclear ER is the site for synthesis, folding, and quality control of most secreted and membrane proteins, as well …

PHLPP-1 negatively regulates Akt activity and survival in the heart.

RATIONALE: The recently discovered PHLPP-1 (PH domain leucine-rich repeat protein phosphatase-1) selectively dephosphorylates Akt at Ser473 and terminates Akt signaling in cancer cells. The regulatory role of PHLPP-1 in the heart has not been …

Pim-1 kinase protects mitochondrial integrity in cardiomyocytes.

RATIONALE: Cardioprotective signaling mediates antiapoptotic actions through multiple mechanisms including maintenance of mitochondrial integrity. Pim-1 kinase is an essential downstream effector of AKT-mediated cardioprotection but the mechanistic …

Kinetics of the translocation and phosphorylation of alphaB-crystallin in mouse heart mitochondria during ex vivo ischemia.

alphaB-crystallin (alphaBC) is a small heat shock protein expressed at high levels in the myocardium where it protects from ischemia-reperfusion damage. Ischemia-reperfusion activates p38 MAP kinase, leading to the phosphorylation of alphaBC on …

LPS-induced autophagy is mediated by oxidative signaling in cardiomyocytes and is associated with cytoprotection.

Bacterial endotoxin lipopolysaccharide (LPS) is responsible for the multiorgan dysfunction that characterizes septic shock and is causal in the myocardial depression that is a common feature of endotoxemia in patients. In this setting the myocardial …
