(Top) Inhibition of the Wnt signaling by 5-aza-2′deoxycytidine and quercetin induces apoptosis of ALL cells. Apoptosis of ALL cells was significantly higher after treatment with quercetin (P < .05). (Bottom) Kaplan-Meier survivor function for patients with ALL. DFS curves for all the patients enrolled in this study, with an adverse impact of hypermethylated WNT inhibitors.
