COPB2 was overexpressed in HCC, and high expression of COPB2 was significantly correlated with higher alpha fetoprotein (AFP) (odds ratio (OR) = 1.616, >20 vs. ≤20, p < 0.05), stage (OR = 1.744, III vs. I, p < 0.05), and grade (OR = 1.746, G4+G3 vs. G2+G1, p < 0.05). This evidence concerns the gene COPB2 and hepatocellular carcinoma.
