Abstract
目的探讨发夹状shRNA封阻c-myc基因,抑制人结直肠癌Colo320细胞增殖、生长的状况。方法针对原癌基因c-myc构建发夹状shRNA的真核表达质粒,并转染人结直肠癌Colo320细胞。荧光定量RT-PCR检测c-myc及细胞端粒酶逆转录酶的mRNA表达,Western-blot检测c-myc、hTERT蛋白表达水平。Southern blot检测端粒的长度,PCR-ELISE法检测端粒酶活性。3H-thymidine实验分析DNA合成和细胞增殖。结果转染细胞增殖、生长皆受到抑制。同时,c-myc和hTERT的mRNA和蛋白表达显著下降,端粒的长度明显缩短,端粒酶活性降低。结论c-myc的shRNA对人结直肠癌Colo320细胞的增殖、端粒长度、端粒酶活性有特异性抑制作用,并呈剂量依赖关系。
