摘要: 目的 探讨Tamoxifen诱导下敲除Pkd1f/f:Cre转基因小鼠多囊肾病1(Pkd1)基因前后的肾功能变化情况。方法 选用出生11 d的Pkd1f/f:Cre转基因小鼠和Pkd1f/f野生型小鼠用Tamoxifen进行诱导, 分别于诱导后7 d、14 d、21 d检测血清肌酐与尿素氮含量, 检测21 d时体质量、肾脏重量及其脏器系数。结果 诱导敲除后7 d小鼠血清肌酐与尿素氮含量开始升高, 14 d、21 d小鼠血清肌酐与尿素氮含量明显升高(P<0.01)。21 d时诱导敲除小鼠肾脏系数明显高于未敲除小鼠。结论 Tamoxifen能使条件诱导敲除pkd1基因的小鼠肾功能产生明显改变, 肾组织出现大量囊泡症状。

Abstract: Objective To explore the change of kidney function of polycystic kidney disease (PKD) mice before and after the knockout Pkd1f/f: Cre gene induced by Tamoxifen induction. Methods The Pkd1f/f:Cre transgenic mice, Pkd1f/f:Cre wild type mice aged on 11 days were induced by Tamoxifen,the contents of serum creatinine and urea nitrogen were detected at 7 days, 14 days and 21days after induction. The body weight, kidney weight and the kidney viscera coefficient were detected after 21 day. Result After 7 days induction, the contents of serum creatinine and urea nitrogen began to rise after 14 days and 21 days induction, the parameters were significantly increased (P<0.01) After 21 days induction,the kidney coefficient of knocked out transgenic mice kidney coefficient was higher than that of wild type mice. Conclusion The renal function of Pkd1f/f:Cre transgenic mice were obviously changed by Tamoxifen induction, the kidney of transgenic mice showed symptoms of a large number of vesicles.
