La quercetina e un flavonoide ubiquitario nei
vegetali Causa arresto della proliferazione di
cellule tumorali Le cellule si arrestano in
G1 Larresto della crescita sembra essere dovuto
ad apoptosi (si osserva rilascio di citocromo c
nel citoplasma)

H1299 e A549 sono due linee cellulari derivate da
tumori del polmone
6
Le frecce indicano i nuclei apoptotici (colorati
