عنوان انگلیسی MiR-145 inhibits cell migration and increases paclitaxel chemosensitivity in prostate cancer cells
چکیده انگلیسی مقاله Objective(s): Prostate cancer (PC) is one of the most commonly diagnosed malignancies among men worldwide. Paclitaxel is a chemotherapeutic agent widely used to treat different types of cancer. Recent studies revealed miRNAs control various genes that influence the regulation of many biological and pathological processes such as the formation and development of cancer, chemotherapy resistance, etc.Materials and Methods: Between three PC cell lines (PC3, DU-145, LNCAP), PC3 showed the lowest miR-145 expression and was chosen for experiments. PC3 cells were treated with paclitaxel and miR-145 separately or in combination. To measure the cell viability, migratory capacity, autophagy, cell cycle progression, and apoptosis induction, the MTT assay, wound-healing assay, and Annexin V/PI apoptosis assay were used, respectively. Moreover, quantitative real-time PCR (qRT-PCR) was employed to measure the expression level of genes involved in apoptosis, migration, and stemness properties.Results: Obtained results illustrated that miR-145 transfection could enhance the sensitivity of PC3 cells to paclitaxel and increase paclitaxel-induced apoptosis by modulating the expression of related genes, including Caspase-3, Caspase-9, Bax, and Bcl-2. Also, results showed combination therapy increased cell cycle arrest at the sub-G1 phase. miR-145 and paclitaxel cooperatively reduced migration ability and related-metastatic and stemness gene expression, including MMP-2, MMP-9, CD44, and SOX-2. In addition, combination therapy can suppress MDR1 expression.Conclusion: These results confirmed that miR-145 combined with paclitaxel cooperatively could inhibit cell proliferation and migration and increase the chemosensitivity of PC3 cells compared to mono treatment. So, miR-145 combination therapy may be used as a promising approach for PC treatment.
