ABSTRACT
Objective To investigate the potential effects of simvastatin on angiotensin Ⅱ-stimulated secretion and proliferation of adrenocortical carcinoma H295R cells.Methods The H295R cells were divided into control group, Angiotensin Ⅱgroup, simvastatin group and Angiotensin Ⅱ plus simvastatin group.Cortisol in medium was determined by chemiluminescent method , and aldosterone was determined by radioimmunoassay .The mRNA expression of 11 beta-hydroxylase ( CYP11B1 ) and aldosterone synthase ( CYP11B2 ) were examined by RT-qPCR.Cell proliferation was detected by MTS method.Results Compared with control group, angiotensin Ⅱincreased the secretion of cortisol and aldosterone, and the expression of CYP11B1 and CYP11B2.Simvastatin decreased cortisol secretion and CYP11B1 mRNA expression ( P<0.05 ) .Simvastatin also inhibited angiotensinⅡ-induced the secretion of cortisol and aldosterone , and the expression of CYP 11 B1 and CYP11 B2 compared with Angiotensin Ⅱgroup ( P<0.05 ) .Angiotensin Ⅱhad no effect on cell proliferation , while simvastatin significantly inhibited cell proliferation .The inhibitory effect of simvastatin on proliferation was enhanced when simvastatin was prescribed with angiotensin Ⅱ( P<0.05 ) .Conclusions Simvastatin inhibits angiotensin Ⅱ-induced secretion of cortisol and aldosterone in H295R cells.Simvastatin inhibits cell proliferation, which could be enhanced by angio-tensin Ⅱ.
