Second, although we identified abnormal miRNAs (hsa-miR-125b-5p and hsa-miR-21-5p) and their target genes (NTF3, PSMD14, CD320, and SORT1), which might be prognostic predictors for HCC using TCGA data, GEO data, and other databases, we also validated gene expression in normal liver cells and HCC cell lines by qRT-PCR, immunohistochemistry, and western blot. Here, NTF3 is linked to hepatocellular carcinoma.
