The development of cardiac hypertrophy in response to increased hemodynamic load and neurohormonal stress is initially a compensatory response that may eventually lead to ventricular dilatation and heart failure. Cellular FLICE-inhibitory protein (cFLIP) is a homologue of caspase 8 without caspase activity that inhibits apoptosis initiated by death receptor signaling. Previous studies showed that cFLIP expression was markedly decreased in the ventricular myocardium of patients with end-stage heart failure. However, the critical role of cFLIP on cardiac remodeling remains unclear. To specifically determine the role of cFLIP in pathological cardiac remodeling, we used heterozygote cFLIP(+/-) mice and transgenic mice with cardiac-specific overexpression of the human cFLIP(L) gene. Our results demonstrated that the cFLIP(+/-) mice were susceptible to cardiac hypertrophy and fibrosis through inhibition of mitogen-activated protein kinase kinase-extracellular signal-regulated kinase 1/2 signaling, whereas the transgenic mice displayed the opposite phenotype in response to angiotensin II stimulation. These studies indicate that cFLIP protein is a crucial component of the signaling pathway involved in cardiac remodeling and heart failure.
