SNAI3 and hepatocellular carcinoma: To further investigate the mechanism underlying the role of SNAI3-AS1 and PEG10 in HCC tumorigenesis, we used two database, starbase V3.0 (ref. 16) and TargetScan17 for biological information prediction, and found that both SNAI3-AS1 and PEG10 are potential targets of miR-27a-3p and miR-34a-5p (Fig. 5a).
