ABSTRACT
AIM:To investigate the effect of ERK1/2/c-Fos signal pathway during angiotensin-(1-7)inhibiting proliferation of rat glomerular mesangial cell strain(GMCS)induced by angiotensin Ⅱ.METHODS:Rat glomerular mesangial cells(GMC)were co-cultured with angiotensin Ⅱ and different doses of angiotensin-(1-7).The numbers of GMC were evaluated by crystal violet staining.The amounts of p-ERK1/2 and c-Fos expressions were detected by Western blotting.RESULTS:Angiotensin-(1-7)showed its inhibitory effects on GMC number increasing induced by angiotensin Ⅱ as well as the amounts of p-ERK1/2 and c-Fos expressions in a concentration dependent manner.CONCLUSION:ERK/c-Fos signal pathway is involved in the inhibitory effects of angiotensin-(1-7)on angiotensin Ⅱ-induced GMC proliferation.
