At the School of Life Sciences at Lanzhou University, G.A. Liu and R.L. Zheng conducted research into the ability of polyphenols (groups of chemicals found in plants) to protect healthy cells against diseases like heart disease and cancer at the cellular level.
The Study
Seven polyphenols were studied, among them resveratrol.
DNA damage was induced by using hydrogen peroxide on human peripheral blood lymphocytes (PBL) which is known to cause single strand breakage in DNA. The researchers then observed the ability of the seven polyphenols to protect the cells against the damage the hydrogen peroxide was invoking on the cellular DNA.
Significant Cell Protection
Resveratrol, as well as others of the seven tested polyphenols, had a substantial impact... »View More

Drs. Steen Mollerup, Steinar ØvrebØ and Aage Haugen from the Department of Toxicology at the National Institute of Occupational Health in Oslo, Norway published a study in 2001 with findings that resveratrol, a red wine ingredient, may effect lung cancer cell expression.
The study suggests that resveratrol, a natural antioxidant found in plants and foods, has cancer preventative and therapeutic potential. Certain red wines are rich sources of resveratrol. A lower risk of lung cancer among consumers of red wine compared with other beverages has been observed, and may be partially attributed to the high resveratrol content in red wine.
The doctors studied the effect of resveratrol on the expression of genes involved in lung cancer. Resveratrol... »View More

The Faculty of Medicine from the Institute of Human Anatomy at the University of Milan in Milan, Italy found that resveratrol, found in grapes and red wine, enhances bacterial ingestion and is a co-factor in anti-inflammatory and cancer prevention activity.
In this experiment, trans-resveratrol has been studied for its anti-inflammatory and anti-cancer qualities. In this research, resveratrol was studied for its immune system defense properties, like causing tumor cell death. Resveratrol enhanced the cell death process of subjects exposed to a certain pathogen.
Even at low concentrations, resveratrol was shown to induce cell death in this experiment. Cells that were treated with red wine resveratrol did not produce tumor properties. The natural... »View More
