In fact, quercetin suppresses cancer cell growth and promotes phase G2 cell cycle arrest and apoptosis in EGFR-overexpressing HSC-3 and TW206 cells, thus inducing the activation of FOXO1, the knockdown of which attenuates the quercetin induction of p21 and Fas ligand (FasL) expression [96]. The gene discussed is EGFR; the disease is cancer.
