A Western blot assay of sh-OGT knockdown efficiency in A2780/DDP cells. A2780/DDP cells were treated with inhibitor-NC + sh-NC, miR-181d inhibitor + sh-NC, or miR-181d inhibitor + sh-OGT. B RT-qPCR detection of miR-181d expression in A2780/DDP cells normalized to U6. C Western blot assay of OGT expression in A2780/DDP cells normalized to β-actin. D CCK-8 assay of A2780/DDP cell viability. E Flow cytometric detection of A2780/DDP cell apoptosis. F Western blot assay of pro-caspase3 and cleaved caspase-3 expression and quantitative analysis in A2780/DDP cells normalized to β-actin. G Western blot assay of PCNA expression and quantitative analysis in A2780/DDP cells normalized to β-actin. A2780 cells were treated with mimic-NC + oe-NC, miR-181d mimic + oe-NC, or miR-181d mimic + oe-OGT. H RT-qPCR detection of miR-181d expression in A2780 cells normalized to U6. I Western blot assay of OGT expression in A2780 cells normalized to β-actin. J CCK-8 assay of A2780 cell viability. K Flow cytometric detection of A2780 cell apoptosis. L Western blot assay of pro-caspase3 and cleaved caspase-3 expression and quantitative analysis in A2780 cells normalized to β-actin. M Western blot assay of PCNA expression and quantitative analysis in A2780 cells normalized to β-actin. Cell experiments were repeated three times independently. *p < 0.05 versus A2780/DDP cells treated with sh-NC, or inhibitor-NC + sh-NC or A2780 cells treated with mimic-NC + oe-NC. #p < 0.05 versus A2780/DDP cells treated with miR-181d inhibitor + sh-NC or A2780 cells treated with miR-181d mimic + oe-NC.
