Plain language summary
There has been increasing interest in plant-based substances that show potential for preventing cancer development. Resveratrol is among these and is found in the skin of grapes, tomatoes and in red wine. Resveratrol displays anti-carcinogenic capacity by neutralising reactive oxygen species and modulating cell proliferation, differentiation and apoptosis. The purpose of this review was to present the characteristics of resveratrol as a bioactive compound and assess the mechanism of its anti-cancer properties. According to many in vitro and in vivo studies, resveratrol is able to inhibit all stages of carcinogenesis in several types of cancer. Based on these findings, the authors conclude there is a need to promote knowledge of the beneficial effects of resveratrol, and that conventional cancer treatment should be supported by an increase of this substance from both foodstuffs and supplements.
Abstract
Over recent years, there has been increasing interest noted in those active substances derived from plants that show potential for preventing cancer development. The most promising candidate is resveratrol which can be found in large amounts in the skin of grapes, tomatoes and in red wine. Its beneficial effects on the human body are seen both in prevention and therapy. The anti-carcinogenic action of resveratrol is linked with its ability to neutralise reactive oxygen species and to modulate cellular processes such as apoptosis, and both cancerous cell proliferation and differentiation. This article presents the characteristics of resveratrol as a bioactive compound derived from natural sources exhibiting anti-cancer properties, which, because of a wide spectrum of biological activities may be used in the prevention of cancer. Many in vitro and animal-based studies have demonstrated such preventative anti-cancer action in the colon, prostate, breast and lungs. The beneficial effects of resveratrol are also presented when adopted as a support to conventional treatments of cancer using chemo- and radio-therapy.
