Representative IHC images showing the expression of STEAP4, PLK1, CDC25C, CDC20, CCNB2, CCNB1, and CDK1 proteins in HCC and adjacent non-tumor tissues. Compared to peritumoral tissues, HCC tissues exhibit lower STEAP4 expression and higher levels of PLK1, CDC20, CDC25C, and CDK1 (n = 7). T: tumor; P: peritumoral tissue. Scale bar: 100 µm
