Adenoviral Gene Transfer of Activated Phosphatidylinositol 3′-Kinase and Akt Inhibits Apoptosis of Hypoxic Cardiomyocytes In Vitro

Abstract

IGF-1 activates PI 3-kinase and Akt in cardiomyocytes. Activated PI 3-kinase and Akt are each sufficient to protect hypoxic cardiomyocytes against apoptosis in vitro. Adenoviral gene transfer provides a useful tool for investigating the role of these signaling pathways in cardiomyocyte apoptosis.
