Abstract

Introduction: MicroRNAs (miRNAs) are single-stranded noncoding RNAs of 21–23 nucleotides that are not translated and have a basic role in gene expression.. They have an important role as a oncogene or tumor suppressor in human cancers.It has been reported that miR-182 in cervical cancer is an oncogene which is inhibited apoptosis in tumor cells. The aims of this study was evaluation of the miR-182 inhibition effect on induction of apoptosis in Cisplatin treated Hela cells.

Methods: The Hela cells were cultured and treated with different doses of Cisplatin, then viability of cells was assessed with MTT and LD50 of Cisplatin in hela cells obtained.  The transfection condition was optimized by using serial dose of lipofectamine and labeled control miR, then optimum concentration of AntimiR-182 was calculated. Finally, AntimiR-182 and cisplatin separately and simultaneously were transfected into Hela cells, and the reduction in cell proliferation and increased of apoptosis rate of treated cells were analyzed by MTT and flow cytometric assay.

Results: The Hela cells which is transfected with both AntimiR-182 and cisplatin became more sensitive to cell death than cells which treated with cisplatin only. We found a significantly increase in cell death (apoptosis and necrosis) from 68% to 81% following the transfection with AntimiR-182 and cisplatin (P<0.05).

Conclusion: The results of the present study shows that expression of miR-182 may have a significant effect in resistance of tumor cells to chemotherapy. Using simultaneously of AntimiR-182 and cisplatin have an additional effect on cisplatin, so, it reduces LD50 of cisplatin. Therefore, AntimiR-182 can be used as a complementary methods of treatment for increasing sensitivity of tumor cells to treatment and decreasing drug resistance.
