Resveratrol interrupts Wnt/β-catenin signalling in cervical cancer by activating ten-eleven translocation 5-methylcytosine dioxygenase 1
Epigenetic modification can be a key weapon employed by both sides of the battle between Cervical Cancer progression due to persistent high-risk papillomavirus (hr-HPV) infection and the development of anti-cancer modalities. Alongside the overactivated Wnt/β-catenin activity, reduced TET1 expression and ratio of 5-hydroxymethylcytosine (5hmC) to 5-methylcytosine (5mC) were found in cervical cancer, which was correlated with lymph node metastasis. After treating cervical cancer cells with Resveratrol (RES), we found that TET1 expression was elevated and Wnt/β-catenin pathway activity was suppressed. Therefore, the aim of this study is to investigate the influence of resveratrol on the TET1 and Wnt/β-catenin pathways, and to elucidate the molecular mechanisms involved in this process, thereby clarifying the potential value of RES in the treatment of cervical cancer. Our data illustrate the TET1-mediated epigenetic modulation was an integral part of the effects of RES on the Wnt/β-catenin pathway in cervical cancer.
