| The deregulation of microRNAs (miRs) has been identified in tumor development. Indeed, the restoration of tumor-suppressive miRs has been associated with inhibited tumor development in various cancers. Herein, we aimed to evaluate the impact of combined miR-383-5p restoration, as a tumor-suppressive miR, with taxol therapy in suppressing MDA-MB-231 breast cancer development. MDA-MB-231 cell line was restored with miR-383-5p and treated with paclitaxel both in combined and separate manners. The MTT experiment was carried out to measure the cytotoxicity of the therapeutic approaches on the tumoral cells. Besides, flow cytometry was conducted to assess apoptosis and cell cycle status following the treatments. Furthermore, the expression levels of critical factors contributed to tumor proliferation, migration, apoptosis were investigated via the qRT-PCR and western blotting techniques. The outcomes pointed out that the miR-383-5p might substantially enhance the chemosensitivity of MDA-MB-231 to taxol. Besides, miR-383-5p restoration and the combined therapy of miR-383-5p restoration with paclitaxel could remarkably increase apoptosis, decrease cell viability, arrest the cell cycle, inhibit clonogenicity, suppress tumor migration, suppress the PI3K/Akt signaling pathway, and down-regulate PD-L1 expression of BC cells. The restoration of miR-383-5p can enhance the chemosensitivity of MDA-MB-231 cells to taxol. Despite the anti-tumoral effects of miR-383-5p restoration on MDA-MB-231 breast cancer development, the combined therapy of miR-383-5p restoration with paclitaxel can be more effective in repressing MDA-MB-231 breast cancer development. |
