摘要:
【摘要】 目的 通过构建N2B神经细胞氧糖剥夺(OGD)/再灌注(R)模型验证miR- 29b对神经细胞的保护作用,探讨Ⅳ型胶原蛋白基因α1(COL4A1)在miR- 29b对神经细胞OGD/R损伤保护作用中的调控机制。方法 正常和缺氧条件培养N2B细胞,实时定量聚合酶链反应(RT- qPCR)检测miR- 29b表达。细胞计数试剂盒(CCK)- 8、克隆形成、Hoechst实验,流式细胞术分别检测不同处理组细胞增殖、凋亡情况。免疫印迹双荧光素酶验证miR- 29b靶基因是否为COL4A1;N2B细胞转染miR- 29b mimics,RT- qPCR和免疫印迹检测COL4A1表达。构建COL4A1 3’非翻译区(UTR)野生型和突变型载体、靶基因,设计合成COL4A1,转染N2B细胞,缺氧培养,CCK- 8、克隆形成、Hoechst实验,流式细胞术检测不同处理组细胞增殖、凋亡情况。 结果 OGD/R细胞中miR- 29b表达较正常细胞组降低。在相同缺氧/复氧条件下培养细胞中miR- 29表达上调,细胞增殖能力明显增强,凋亡明显抑制。miR- 29b表达上调抑制COL4A1表达,但转染COL4A1及其对照组后,COL4A1对照组细胞增殖明显高于过表达组,凋亡明显低于过表达组。 结论 miR- 29b对N2B神经细胞OGD/R模型具有保护作用,通过抑制COL4A1表达减轻缺氧对N2B神经细胞的损伤。miR- 29b可通过调节COL4A1表达减少缺血/缺氧再灌注对神经细胞的损伤。
