摘要 目的:探讨Notch信号通路在尿酸钠结晶(MSU)促进大鼠肾小管上皮细胞(NRK-52E)Snail表达中的作用。方法:用500mg/LMSU刺激NRK-52E细胞24、48、72h;另外用Notch信号通路抑制剂(γ分泌酶抑制剂,DAPT)和MSU共同刺激NRK-52E细胞24、48、72h。采用Real-time PCR检测Snail的mRNA表达量,采用Real-time PCR、Western印迹检测Jagged1、Notch1的mRNA及蛋白的表达量。结果:MSU刺激NRK-52E细胞后Snail、Jagged1和Notch1的表达量较之正常组细胞明显上调;而经DAPT阻断Notch信号通路后,MSU诱导Snail、Jagged1、Notch1上调的趋势被明显逆转。结论:尿酸钠结晶可以诱导NRK-52E的Snail表达增高,Notch信号通路在这一过程中起重要的调控作用。
