The upregulation of signal transducer and activator of transcription 5-dependent microRNA-182 and microRNA-96 promotes ovarian cancer cell proliferation by targeting forkhead box O3 upon leptin stimulation.
To examine whether overexpression of MIR182 and its target genes, including BRCA1, HMGA2 (high-mobility group A2), FOXO3 and MTSS1, are associated with high-grade serous ovarian carcinoma tumor types and clinical outcome, we studied MIR182 by in situ hybridization and its target gene expression by immunohistochemistry in 117 cases of advanced ovarian cancer.
Downregulation of DNMT3a expression increases miR-182-induced apoptosis of ovarian cancer through caspase-3 and caspase-9-mediated apoptosis and DNA damage response.
