抑制单羧酸转运蛋白1可增强鼻咽癌细胞HNE1/DDP对顺铂诱导凋亡的敏感性
发布时间:2021-09-04 20:41
目的探讨siRNA沉默单羧酸转运蛋白1(MCT1)增强鼻咽癌细胞HNE1/DDP对顺铂诱导凋亡的敏感性及其可能机制。方法 Western blot检测HNE1和HNE1/DDP细胞中MCT1的表达及siRNA转染沉默MCT1在HNE1/DDP细胞中MCT1的表达;MTT法检测不同浓度顺铂和MCT1 siRNA联合顺铂对HNE1/DDP细胞的增殖抑制作用;PI单染流式细胞术检测细胞凋亡;线粒体膜电位检测试剂盒(JC-1)检测细胞线粒体膜电位;Western blot检测Mcl-1、Bak、Bcl-2、Bax蛋白的表达。结果 MCT1在HNE1/DDP细胞中高表达,抑制MCT1的表达可增加HNE1/DDP细胞对顺铂的敏感性(P<0.05),部分逆转鼻咽癌细胞对顺铂的耐药。此外,抑制MCT1的表达可增强HNE1/DDP细胞对顺铂诱导凋亡的作用,MCT1 siRNA与8μmol/L顺铂联合作用于HNE1/DDP细胞24 h的凋亡率为(51.23±2.86)%,较单用MCT1 siRNA、顺铂的凋亡率明显升高(P<0.05)。同时使细胞线粒体膜电位降低,下调Mcl-1、Bcl-2的表...
