Abstract:
Cardiac hypertrophy is a major adaptational mechanism in stresses such as pressure overload and neurohumoral stimulation.As powerful vasoconstrictor peptides in cardiovascular system,especially the vascular endothelium,smooth muscle cells and cardiocyte,ETs play important physiological roles in the regulation of normal cardiovascular function.Excessive generation of ETs in local cardiac muscle has been linked to myocardial hypertrophy.Endothelin-1(ET-1) in cardiac muscle exerts its actions in the development of myocardial hypertrophy through binding to specific receptors and interacting with other vasoactive substance of local tissues.ET-1 can induce the hypertrophy for cardiocytes and the proliferation for cardiac fibroblasts by ETA.ETB receptors are implicated both in initiating and maintaining myocardial hypertrophy.As a new target of drug,ET receptors have become the research focus,and great progress has been made on the development of the ET antagonists.
