Non-coding RNA Regulation in Ovarian Cancer: MicroRNAs (miR-203a-3p, etc.)and long non-coding RNAs (such as OIP5-AS1) regulate ZEB1 and other epithelial–mesenchymal transition-related genes through epigenetic mechanisms to promote ovarian cancer metastasis [119]. The gene discussed is ZEB1; the disease is ovarian carcinoma.
