Abstract: Urotensin II(U-II),a cyclic peptide has been initially identified as a neuropeptide of teleost fish.Subsequently,U-II has been characterized in the brain of the Europeangreen frog and has also been cloned from the human genome.Human U-II(human U-II,hU-II),composed of 11 amino acid residues is rich in cardiovas-cularand nervous system.As an endogenous ligand forUT receptor,hU-II exerts a broad spectrum of biological actions,such as vasoconstriction and vasorelaxation,fa-cilitating proliferation of cardiac cells,regulating the car-diac function and playing an important role in pathogene-sis of some cardiovasculardiseases such as coronary heart disease and cardiac failure.The effects of hU-II on card-iovascularsystem were briefly reviewed as follows.
