Abstract:

Cervical cancer is a common gynecological malignant tumor with high morbidity and mortality. DKK3 (dickkopf-3) is an antagonist of the classic Wnt signaling pathway and a tumor suppressor gene discovered in recent years. DKK3 exerts its anti-tumor function by regulating β-catenin signal transduction pathway, reversing epithelial-mesenchymal transition, inhibiting tumor angiogenesis and other pathways. It is a potential target in tumor therapy. Epigenetic modification of genes, especially promoter methylation, plays a very important role in the occurrence and development of a variety of malignant tumors. Hypermethylation in the promoter region of DKK3 gene is an important reason for the inactivation of DKK3 protein, which makes the Wnt signaling pathway abnormally activated, leading to the occurrence of tumors. The expression of DKK3 is often down-regulated in cervical cancer tissues, and the silencing of DKK3 expression caused by the methylation of the gene promoter is a frequent event in cervical cancer. The methylation level and expression level of DKK3 are significantly correlated to the prognosis of patients with cervical cancer, and it has a good predictive effect. Therefore, in-depth study on the relationship between DKK3 and cervical cancer may provide new ideas for the mechanism research, targeted therapy and prognosis judgment of cervical cancer.
