In terms of the diagnostic potentials of the various genes, only LINC01116, TMSB15A, PLAU, OLFML2B, and MRC2 were found to have the potential of aiding in HCC diagnosis (all AUC ≥ 0.700, all P ≤ 0.05, Fig. 3A, D-F, J, Table S2) but had not in other biomarkers (all AUC < 0.700, Fig. 3B, C, G, H, I, K). This evidence concerns the gene TMSB15A and hepatocellular carcinoma.
