role of protein kinase C-epsilon (PKCepsilon) in ischemic preconditioning cardioprotection induced by enhancement of cell volume regulation.
Written in English
Enhancement of cell volume regulation is a key mechanism of cardioprotection induced by ischemic preconditioning. The specific role of PKC&egr; in modulating IPC protection against necrosis via an enhanced volume regulatory mechanism was addressed using a combined molecular and pharmacological approach in primary culture of adult rabbit cardiomyocytes. It was found that (1) PKC&egr; protects against ischemic cell death in a pathway that includes Cl - channel activity downstream, (2) PKC&egr; limits the extent of ischemic cardiomyocyte swelling with Cl- channel activity downstream of PKC&egr;, (C) PKC&egr; is involved in normal cell volume regulation in oxygenated cardiomyocytes, and Cl- activity is downstream of PKC&egr; in this response. The findings of this study support the hypothesis that the mechanism of PKC&egr; - mediated cardioprotection includes the activation of potent cell volume regulatory mechanisms, which delay ischemic cell swelling and cell death and involve the activation of volume regulated Cl- channels.

Background: Mitochondrial aldehyde dehydrogenase 2 (ALDH2) is a key enzyme for the metabolism of many toxic aldehydes such as acetaldehyde, derived from alcohol drinking, and 4HNE, an oxidative stress-derived lipid peroxidation -translational enhancement of ALDH2 activity can be achieved by serine/threonine phosphorylation by epsilon protein kinase C (εPKC). The protein kinase C pathway plays a central role in the fibroblast growth factor-stimulated expression and transactivation activity of Runx2. The Journal of biological chemistry Jan 3;(1)

Data obtained from adult cohorts have implicated activation/translocation of protein kinase C (PKC)-epsilon as an important cellular mediator of myocardial infarct size reduction with ischemic preconditioning (PC). Age-related alterations in cellular signaling may, however, confound the extrapolation of mechanistic insight derived from adults to the aging population, the specific subset in Cited by:

Protein kinase C epsilon (PKC ɛ) is one of major isoforms in novel PKC family. Although it has been extensively characterized in the past decade, the role of PKC ɛ in neuron is still not well. Protein kinase C epsilon type (PKCε) is an enzyme that in humans is encoded by the PRKCE gene.
PKCε is an isoform of the large PKC family of protein kinases that play many roles in different tissues. In cardiac muscle cells, PKCε regulates muscle contraction through its actions at sarcomeric proteins, and PKCε modulates cardiac cell metabolism through its actions at s: PRKCE, PKCE, nPKC-epsilon, protein kinase.

Protein kinases exhibit clear preferences in the substrates that they phosphorylate as well as the sites within substrates that they recognize (for a review, see Kemp and Pearson ).The selective phosphorylation of Ser14 in phosphorylase by phosphorylase kinase is an excellent example of this specificity (Krebs and Fischer ).In subsequent studies, the cAMP-dependent protein kinase was.
