A group of researchers reported that miR-302b inhibits tumorigenesis by targeting EphA2 via EMT signaling cascade in gastric cancer (Huang et al. 2017), and others found that miR-125b-5p can function as a tumor suppressor in esophageal squamous cell carcinoma (Mei et al. 2017). This evidence concerns the gene EPHA2 and gastric cancer.
