NQO1 and gastric cancer: The results from the Kaplan–Meier survival analysis tool (16) showed that three transcript isoforms of NQO1 (including 201467_s_at, 201468_s_at, and 210519_s_at) all demonstrated that the gastric cancer patients with a higher expression of NQO1 had a favorable overall survival (OS) probability (Supplementary Figures S1A-C).
