摘要
目的观察血管紧张素-（1-7）[Ang-（1-7）]对血管紧张素-Ⅱ（Ang-Ⅱ）诱导的肾小球系膜细胞（GMC）增殖过程中c-fos表达的影响。方法体外培养GMC，Ang-Ⅱ为刺激因子，不同浓度Ang-（1-7）为干预因子。用结晶紫计数法检测GMC数目的变化；Western blot检测GMC中c-fos蛋白表达的变化。结果Ang-（1-7）呈剂量依赖性地抑制Ang-Ⅱ诱导的GMC增殖和GMC内c-fos蛋白表达。结论Ang-（1-7）可能通过抑制c-fos的表达，抑制Ang-Ⅱ诱导的GMC增殖。
Objective To investigate the effect of angiotensin-（1-7） on the expression of cellular c-fos in angiotensin Ⅱ-induced proliferative glomerular mesangial cells （GMC）. Methods GMC were treated with angiotensin Ⅱ and different dose of angiotensin-（ 1-7 ）.GMC number were evaluated by crystal violet staining and the expression of c-fos were detected by western blot..Results Angiotensin-（1-7）inhibit angiotensin II Ⅱ-induced GMC proliferation as well as the expression c-fos in a concentration dependent manner. Conclusion c-fos is involved in the inhibiting effects of angiotensin-（1-7） on angiotensin Ⅱ-induced GMC proliferation.
