Another study demonstrated that quercetin-induced autophagy reduced its therapeutic effect on gastric cancer (GC) cells, and treatment with quercetin combined with miR-143 agonist, an inhibitor of autophagy in GC cells targeting GABARAPL1, could improve the antitumor efficacy of quercetin (Du et al., 2015). The gene discussed is GABARAPL1; the disease is gastric cancer.
