Objective In this study,we aimed to detect the expression of miR -199 and searched for chemo-therapy sensitivity of indicators in ovarian cancer cell lines and.Methods Omics analysis had found that in ovarian cancer cell lines which had different sensitivities to cisplatin,the difference of expression of miR -199 is significant. Then used specificity methylation PCR and western blot to verify the expression level of P63 gene in ovarian cancer cell lines of the transient transfection miR199 mimic /antagomir.Results The expression level of miR-199 in ES-2 is much higher than in the expression of SKOV3 cells.The expression of p63 is negatively correlated with the expression of miR-199.Conclusions miR-199 and P63 may predict the sensitivity to cisplatin chemotherapy to some extent. miR-199 may effect the sensitivity to cisplatin chemotherapy of ovarian cancer by regulating its downstream target genes P63.%目的探讨 miR-199在卵巢癌细胞株中的表达，寻找卵巢癌化疗敏感性的指标。方法组学分析找出在顺铂敏感性不同的卵巢癌细胞株，miR-199的表达量差异较为显著，qRT-PCR 和 western blot 方法检测瞬时转染 miR199 mimic ／antagomir 后的卵巢癌细胞株，P63表达水平发生显著变化。结果miR-199在对顺铂耐药的 ES-2细胞中表达水平高于在对顺铂耐药的 SKOV3细胞中的表达，miR-199的下游蛋白 P63的表达也有差异。结论miR-199与 P63在一定程度上可以预测卵巢癌顺铂化疗敏感性，miR-199可能是通过其下游靶基因 P63发挥其在卵巢癌顺铂化疗敏感性中的作用。
