Inhibition of Hep G2 cell proliferation by STEAP4 with copper reductase activity. A, B The 5-Ethynyl-2′-deoxyuridine (EdU) staining reveals reduced cell proliferation rates following STEAP4 overexpression with 50 μM copper co-treatment. C GSEA of the LICH-TCGA cohort highlights STEAP4 co-expressed genes linked to cell cycle regulation. * p < 0.05
