Abstract
Resveratrol is a representative polyphenol of diet‑derived putative cancer chemopreventive agents, which have attracted increasing interest in the cancer chemoprevention community. The inhibition of the action of human papillomavirus (HPV) E6 and E7 has been considered a key approach for cervical cancer therapy. Resveratrol has been shown to induce the apoptosis, and reduce both the viability and mitotic index of a number of cancer cell lines, including human cervical cancer cells. In the present study, it was confirmed that resveratrol inhibited the HPV E6 mRNA, HPV E6 protein and phosphorylated retinoblastoma protein (p‑pRb1) levels, and increased the p53 protein levels in HeLa and Ca Ski cells, as well as in subcutaneous tumor tissue grown from HeLa cells. High‑risk HPV uses a bicistronic RNA to control E6 and E7 genes simultaneously. On the whole, the present study demonstrates that resveratrol inhibits cervical cancer development by suppressing the transcription and translation of E6 and E7, and also by promoting the apoptosis and G1/S phase transition arrest. These findings may provide the basis for the development of resveratrol as a candidate for cervical cancer therapy.
