miR-30a and miR-497 inhibit EMT and metastasis in breast cancer [153,154] while miR-204 and miR-630 inhibit EMT and tumor metastasis by targeting Slug in cholangiocarcinoma [155] and hepatocellular carcinoma [156], and miR-203 targets Slug in glioblastoma, promoting EMT [157]. Here, SNAI2 is linked to neoplasm.
