Another frequently reported target gene of miR-124 is the enhancer of zeste homolog 2 (EZH2), which has been found in lung adenocarcinoma [67], hepatocellular carcinoma cancer [87,88], cholangiocarcinoma [107], laryngeal squamous cell carcinoma [114], multiple myeloma [115], and ovarian cancer [23]. This evidence concerns the gene EZH2 and lung adenocarcinoma.
