摘要
目的:观察RNA干扰沉默mdrl基因后化疗药物对卵巢癌耐药细胞株SKOV3 /ADM增殖的影响。方法:RT -PCR检测靶向于mdrl基因的小发夹状RNA(pshRNA -mdrl)对SKOV3 /ADM细胞内mdr1mRNA表达的影响;采用MTT法及软琼脂克隆形成实验测定pshRNA -mdrl联合化疗药物阿霉素对SKOV3 /ADM的增殖抑制作用。结果:pshRNA -mdrl能抑制SKOV3 /ADM细胞mdr1mRNA的表达,pshRNA -mdr1联合阿霉素明显抑制SKOV3 /ADM细胞的增殖。结论:靶向于mdr1的pshRNA联合阿霉素能显著抑制SKOV3 /ADM的增殖。
Objective:To investigate the effect of RNA interference targeting mdrl gene with ADM on ovarian cancer resistant strain SKOV 3/ADM.Methods:The expression of mdrlmRNA after transfected pshRNA-mdrl was detected by RT-PCR;MTT test and clone forming test were applied to measure the inhibition combined with adriamycin on proliferation of SKOV 3/ADM strain.Results:These pshRNA-mdrls inhibited the expression of mdrlmRNA and proliferation of SKOV 3/ADM obviously when combined with adriamycin.Conclusion:The short hairpin RNA recombinant plasmid targeting mdrl gene combined with adriamycin inhibits the proliferation of SKOV 3/ADM and increases the sensitivity to chemotherapy.
