“Quercetin, the major constituent of flavonoid and widely present in fruits and vegetables, is an attractive compound for cancer prevention due to its beneficial anti proliferative effects, showing a crucial role in the regulation of apoptosis and cell cycle signaling.
In vitro studies have demonstrated that quercetin specifically influences colon cancer cell proliferation.
Our experiments, using human colon adenocarcinoma cells, confirmed the anti proliferative effect of quercetin and gave intriguing new insight in to the knowledge of the mechanisms involved…
These findings open new perspectives for anticancer therapeutic strategies.”
