Our experiments, using human colon adenocarcinoma
cells, confirmed the anti-proliferative effect of quercetin
and lent intriguing new insight into the knowledge of
the mechanisms involved leading to the regulation of
cell growth. These findings open new perspectives for
anticancer therapeutic strategies.”
