WNT5A and ovarian carcinoma: The objective of this study was to understand the relationship between Wnt5a promoter methylation and epithelial ovarian cancer, observe the methylation status of the promoter region of the Wnt5a gene, explore the change in transcriptional expression and cell biological characteristics when treating with the demethylating agent 5-Aza-CdR, and finally provide a mechanistic basis to support the use of demethylating agents in the treatment of epithelial ovarian cancer.
