Webnormal leptin signaling is necessary to prevent age-related myocyte apoptosis and LV hypertrophy and that PI3K is a critical compo-nent of the leptin signaling axis. The decrease in p110α catalytic activity could explain the development of increased myocyte apop-tosis and cardiac hypertrophy in these obese mouse models. Introduction WebPurkinje fibers are a unique cardiac end-organ. Further histologic examination reveals that these fibers are split in ventricles walls. The electrical origin of atrial Purkinje fibers arrives from the sinoatrial node . Given no aberrant channels, the Purkinje fibers are distinctly shielded from each other by collagen or the cardiac skeleton .
