產品描述:
Urotensin II is a peptide vasoconstrictor and agonist of the urotensin (UT) receptor (Ki = 2.06 nM for the human recombinant receptor expressed in HEK293 cells).1 It stimulates intracellular calcium mobilization in HEK293 cells expressing human and rat UT (EC50s = 0.47 and 0.78 nM, respectively) but decreases intracellular calcium concentration in goby (G. mirabilis) enterocytes when used at a concentration of 500 nM.2 Urotensin II (20 mU/ml) stimulates active sodium and chloride absorption across isolated goby posterior intestine in 5% seawater-adapted solution.3 In vivo, urotensin II (1.5-150 nmol/kg) decreases diastolic blood pressure and increases heart rate in anesthetized rats.4 It also reduces the pressor responses to sympathetic nerve stimulation, norepinephrine , and vasopressin in pithed rats when administered at a dose of 150 nmol/kg.
