The miRPathv4-identified targets are not necessarily listed in our Table 1; miR-122-5p, for example, has 32 gene targets regarding proteoglycans in cancer and 16 targets regarding TGF-B/SMAD signaling, and our Table 1 only lists 7 targets for this miRNA in HCC studies. This evidence concerns the gene TGFB1 and hepatocellular carcinoma.
