For example, microRNA-375, miR-29c, miR-195, miR-625, miR-203, miR-302b, miR-133a, miR-101, miR-27a, miR-655 and miR-200b can suppress the growth of ESCC cells by regulating the expression of a variety of molecules, including IGF1R (insulin-like growth factor 1 receptor), cyclin E, Cdc42, Sox2, Ran, ErbB4, FSCN1 and MMP14, enhancer of zeste homolog 2 (EZH2), KRAS, ZEB1, TGFBR2 and Kindlin-2. This evidence concerns the gene RAN and esophageal squamous cell carcinoma.
