Alisertib对结直肠癌的抗肿瘤作用的KRAS基因突变特异性及机制研究
发布时间:2021-04-07 20:03
结直肠癌(CRC)是世界范围内最常见的恶性肿瘤之一,具有很高的发病率和死亡率。RAS基因突变存在于大部分致命的人类肿瘤中,并且在约45%的CRC中发生。不同KRAS基因突变具有特有的生物学功能。Alisertib(ALS)是一种小分子靶向药物,选择性抑制Aurora A激酶,体内体外实验证实有强大的抗癌作用,但ALS对不同KRAS基因突变的CRC的抗癌作用尚不清楚。目的1、探讨ALS作用于不同KRAS基因突变的结直肠癌细胞的特异性;2、探讨ALS作用于结直肠癌HT29和Caco-2细胞的蛋白质组变化、分子靶点;3、检测ALS对HT29和Caco-2细胞的RAS通路的影响、程序性细胞死亡的作用及分子学机制;4、检测ALS联合MEK抑制剂Selumetinib对结直肠癌细胞的RAS信号通路的抑制作用及对程序性细胞死亡的作用。方法本研究采用人不同KRAS基因突变的结直肠癌细胞株Caco-2(KRAS WT),Colo-678(KRAS G12D),SK-CO-1(KRAS G12V),HCT116(KRAS G13D),CCCL-18(KRASA146T)和HT29(BRAFV600E)进行...
