Objectives: The present study examined the possibility that intracellular ATP levels dictate whether hypoxic cardiac myocytes die by apoptosis or necrosis. Background: Although apoptosis and necrosis may appear to be distinct forms of cell death, recent studies suggest that the two may represent different outcomes of a common pathway. In ischemic myocardium, apoptosis appears early, while energy stores...
Normal cardiac function requires a tight interaction between metabolism, contractile function and gene expression. The main perturbation challenging this equilibrium in vivo is ischemia, which alters energy flux through the control of key enzymes. The review highlights metabolic imprints and energetic aspects of programmed cell survival, programmed cell death, and of necrosis. When sustained and severe,...
