G6PD and gastric cancer: To explore miRNAs which regulates G6PD in gastric cancer, bioinformatics analysis (ENCORI database and TargetScan V7.2 database) was used to predict targeted miRNAs for G6PD. In the meantime, the Human microRNA Disease Database (HMDD v3.2) was applied to predict miRNAs related to the progress of gastric cancer.
