Abstract: Endothelins (ETs) are composed of 21-aminoacids produced by endothelial cells and considered to be potent vasoconstrictor. Recent studies found that they could not only induce the angiogenesis, mitosis and differentiation, but also act the role of cytokines. Previous studies have identiifed three isoforms of ET (ET-1, ET-2 and ET-3), which are involved in a variety of physiological and pathological processes. ET-1 is most potent one among ETs, whereas ET-3 is the weakest once. ET peptides exhibit their functions in a number of mammalian physiological systems, including gastrointestinal. ETs act via two distinct isoforms of receptors in human body, i.e. endothelin receptor A (ETA) and endothelin receptor B (ETB), which can be found expressed in many mammalian cardiovascular system, neural system and gastrointestinal tract. ETA and ETB have same signaling pathways. And at the meantime, ETB can promote the activation of PLA2. The study also found that endothelins were widely associated with benign and malignant diseases.
