摘要:

目的:探讨microRNA-139-5p(miR-139-5p)靶向调控S100钙结合蛋白A4(S100A4)基因介导Wnt信号通路对2型糖尿病(T2DM)大鼠胰岛β细胞凋亡的影响。方法:构建T2DM大鼠模型;通过组织和细胞实验证实糖尿病大鼠miR-195-5p/S100A4/Wnt通路相关因子表达失调;检测各组胰岛β细胞中GSK-3β、PDX-1以及凋亡相关因子(Bax、Bcl-2)的表达并检测各组细胞周期和凋亡情况。结果:过表达miR-139-5p或沉默S100A4能够抑制T2DM大鼠胰岛β细胞中Wnt通路相关因子表达,抑制GSK-3β、Bax表达,促进PDX-1、Bcl-2表达,G0/G1期细胞比例下降,S期细胞比例上升,抑制胰岛β细胞凋亡(均P<0.05);miR-139-5p inhibitor组各项指标表达与miR-139-5p mimic组相反。结论:miR-139-5p能够靶向抑制S100A4基因,抑制Wnt信号通路激活,从而减少T2DM大鼠胰岛β细胞凋亡。
