摘要
本研究旨在探讨马兜铃酸肾病(AAN)中标志性因子的表达变化。30只小鼠灌胃8mg/(kg·d)马兜铃酸Ⅰ(AAⅠ),于不同时间处死,用常规病理切片染色法观察肾脏不同时间段的病理变化程度,以实时荧光定量PCR和Western blotting检查各组小鼠肾组织细胞标志性蛋白α-平滑肌肌动蛋白(α-SMA)、角蛋白18(CK-18)、波形蛋白(vimentin)的表达变化。结果显示随着AAⅠ用药时间的延长,肾脏损伤逐渐加重,并证实AAⅠ可诱导小鼠肾脏发生上皮—间质转分化(EMT),促进α-SMA、vimentin的mRNA及蛋白表达增加,抑制CK-18的表达,为AAN更深一步的机制研究提供有力的理论基础。
The study was aimed to observe the expression changes of relative factors in mice with aristolochic acid nephropathy(AAN).30 mice were given aristolochic acidⅠ(AAⅠ)at 8mg/(kg·d),and mice were killed at a different time.Then observe the renal pathological changes by hematoxylin-eosin(HE),Real-time PCR and Western blotting technology were used to detect the expression changes ofα-SMA,vimentin and CK-18.The results showed that with the extension of treatment time,we could found the kidney structure was damaged more seriously,and confirmed that AAⅠ could induce epithelial-mesenchymal transition(EMT)in renal,promoted the expression ofα-SMA and vimentin,inhibited the expression of CK-18.The study laid a foundation for a deeper mechanism study of AAN.
