Figure 4: Validation of nine selected proteins in clinical HCC tissues by western blotting.

The abundance of FBXO2, ACSL4, PLIN2, PKM2, GFPT1, CYP1A2, FTCD, UGT2B7 and PCK2 proteins in HCC and adjacent non-HCC liver tissues were analysed by western blotting using six pairs of samples. The GAPDH protein was used as an internal reference.
