For example, miR-124 downregulates PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha), suppressing the proliferation of HCC cells (36); miR-124-3p inhibits the invasiveness and metastasis of HCC cells by targeting CRKL (Crk-like protein) (37); and miR-124-3p regulates FGF2 (fibroblast growth factor 2)-EGFR pathway to overcome pemetrexed resistance in lung adenocarcinoma cells by targeting MGAT5 (alpha-1,6-mannosylglycoprotein 6-beta-N-acetylglucosaminyltransferase) (38). This evidence concerns the gene MGAT5 and lung adenocarcinoma.
