VAPB缺失诱导自噬的机制研究
发布时间:2022-07-13 15:12
目的:自噬在神经退行性疾病中扮演着重要的角色。本研究考察囊泡相关膜蛋白相关蛋白B(VAPB)是否参与自噬调控及其机制研究。方法:我们分别在HEK293T、HeLa和SH-SY5Y三种细胞系中,转染了两种VAPB干扰小RNA来沉默VAPB的表达,利用蛋白免疫印迹法(Western blot)检测细胞中LC3和Beclin 1的蛋白水平。在HEK293T细胞中过表达FLAG-VAPB,检测细胞中的LC3和Beclin 1的蛋白水平。在HEK293中敲减VAPB,同时过表达GFP-LC3和FLAG-P62,通过免疫荧光的方法,检测GFP-LC3和FLAG-P62的共定位情况。在HEK293T细胞中沉默VAPB的表达,通过实时定量PCR(Real-time q PCR)检测Beclin1 m RNA水平的变化。在HEK293T细胞中同时沉默VAPB和Beclin 1的表达,检测细胞中的LC3蛋白水平。在m Cherry-LC3稳定转染的HEK293细胞中,同时沉默VAPB和Beclin 1的表达,检测细胞中m Cherry-LC3点状聚集的数量。在HeLa细胞中,敲减VAPB后过表达m Che...
