血管紧张素Ⅱ对足细胞Notch通路及Nephrin表达的影响
Chinese Pharmacological Bulletin(2015)
Abstract
目的探讨血管紧张素Ⅱ(AngⅡ)刺激小鼠足细胞对Notch通路、Nephrin表达的影响。方法 AngⅡ刺激小鼠足细胞并给予缬沙坦干预,采用免疫荧光化学、Western blot、Real-time PCR方法检测Notch1、Notch胞内域1(NICD1)、Hes1、Nephrin的表达情况。结果 AngⅡ呈时间依赖性增加足细胞Notch1、NICD1、Hes1表达,抑制Nephrin表达(P<0.01);缬沙坦可抑制AngⅡ对Notch通路的活化,增加Nephrin的表达(P<0.01)。结论 AngⅡ通过激活Notch通路降低足细胞Nephrin表达。
