By analyzing the above information, we chose a group of miR-124 regulated target genes (PDCD6, ROCK1, SLUG, STAT3, TGF-β, ZEB1), involved in the main biological processes in several common epithelial cancers, including lung, gastric, hepatocellular, breast and ovarian cancer, which is shown in Figure 1. Here, SNAI2 is linked to ovarian cancer.
