Effects of resveratrol on the proliferation, apoptosis and telomerase ability of human A431 epidermoid carcinoma cells

The aim of the present study was to investigate the effect of resveratrol on cell apoptosis, ability of telomerase and the human telomerase reverse transcriptase (hTERT) protein expression in human A431 epidermoid carcinoma cells. A431 cells were treated with different concentrations of resveratrol, and the cell appearance was then observed under a microscope. In addition, the cell proliferation was examined using an MTT assay, and the ability of telomerase was detected using telomeric repeat amplification protocol-polymerase chain reaction-ELISA. Resveratrol significantly inhibited the ability of telomerase and decreased the expression of hTERT protein in a concentration-dependent manner. In conclusion, resveratrol is capable of downregulating the expression of hTERT protein and inhibits the ability of telomerase of A431, which is an important mechanism of action of resveratrol with regard to inhibition of A431 cell proliferation.
