CRIP1(cysteine-rich intestinal protein 1)是含有双锌指结构域的蛋白,在很多肿瘤细胞中高表达,但其在肺癌细胞中的生理学功能尚不明确。本研究应用定量蛋白质组学探究CRIP1过表达对肺癌顺铂耐药细胞(A549/DDP)的影响及作用机制。运用...CRIP1(cysteine-rich intestinal protein 1)是含有双锌指结构域的蛋白,在很多肿瘤细胞中高表达,但其在肺癌细胞中的生理学功能尚不明确。本研究应用定量蛋白质组学探究CRIP1过表达对肺癌顺铂耐药细胞(A549/DDP)的影响及作用机制。运用慢病毒载体系统构建了CRIP1过表达的A549/DDP稳转细胞系,利用Western Blotting证实了单克隆细胞系中CRIP1的过表达。发现CRIP1过表达能够加快细胞增殖,增加细胞的耐药性。通过定量蛋白质组学分析,鉴定了CRIP1过表达引起的蛋白质组的变化,并且对上调和下调的蛋白进行聚类分析。结果表明,CRIP1过表达上调了烟酰胺磷酸核糖转移酶(NAMPT)和NAD依赖型氧化还原酶的表达,从而促进细胞的增殖,并且提高了细胞的耐药性。展开更多
