A Expression of miR-181d in DDP-resistant and DDP-sensitive OC cells in the GSE148251 dataset. B In-situ hybridization assay of the miR-181d expression in clinical tissue samples of chemo-resistant (n = 46) and chemo-sensitive (n = 32) OC patients. C CCK-8 assay evaluation of viability of A2780 and A2780/DDP cells after treatment with DDP at different concentrations (0, 10, 20, 50, 100, and 150 μmol/L) for 48 h. IC50 of A2780 = 12.72 μmol/L, and IC50 of A2780 DDP = 55.03 μmol/L. D RT-qPCR detection of miR-181d expression in A2780/DDP and A2780 cells, normalized to U6. Cell experiments were repeated three times independently. *p < 0.05 versus A2780 cells or chemo-sensitive OC patients.
