This study examines the role of Shc proteins in PAR-1-dependent signaling pathways that influence ventricular remodeling. We show that thrombin increases p46Shc/p52Shc phosphorylation at Tyr(239)/Tyr(240) and Tyr(317) (and p66Shc-Ser(36) phosphorylation) via a pertussis toxin-insensitive epidermal growth factor receptor (EGFR) transactivation pathway in cardiac fibroblasts; p66Shc-Ser(36) phosphorylation is via a MEK-dependent mechanism. In contrast, cardiac fibroblasts express beta(2)-adrenergic receptors that activate ERK through a pertussis toxin-sensitive EGFR transactivation pathway that does not involve Shc isoforms or lead to p66Shc-Ser(36) phosphorylation. In cardiomyocytes, thrombin triggers MEK-dependent p66Shc-Ser(36) phosphorylation, but this is not via EGFR transactivation (or associated with Shc-Tyr(239)/Tyr(240) and/or Tyr(317) phosphorylation). Importantly, p66Shc protein expression is detected in neonatal, but not adult, cardiomyocytes; p66Shc expression is induced (via a mechanism that requires protein kinase C and MEK activity) by Pasteurella multocida toxin, a Galpha(q) agonist that promotes cardiomyocyte hypertrophy. These results identify novel regulation of individual Shc isoforms in receptor-dependent pathways leading to cardiac hypertrophy and the transition to heart failure. The observations that p66Shc expression is induced by a Galpha(q) agonist and that PAR-1 activation leads to p66Shc-Ser(36) phosphorylation identifies p66Shc as a novel candidate hypertrophy-induced mediator of cardiomyocyte apoptosis and heart failure."xsd:string |
