Abstract:
Objective To investigate the effects of Urotensin Ⅱ(UⅡ)on proliferation of rat pheochromocytoma cell line(PC12) and primary cultured human pheochromocytoma cells.Methods We observed the effects of UⅡ on the proliferation of rat PC12 cells and human pheochromocytoma cells in vitro by MTT method.Results 1.UⅡ had no obvious effect on the proliferation of rat PC12 cells.2.UⅡ(at 10-7 and 10-6mol/L) promoted the proliferation of primary cultured human pheochromocytoma cells. Conclusion UⅡ stimulates the proliferation of human pheochromocytoma cells and probably plays a role in the pathogenesis of pheochromocytoma.
