UBQLN2 and hepatocellular carcinoma: We found that Ubqln2 had significant relations with tumor size (Pearson χ2 test, P = .005), UICC stage (Pearson χ2 test, P = .003) and recurrence (Pearson χ2 test, P = .009) in HCC (Table 2), and the HCC samples with high Ubqln2 expression had a larger tumor size than the HCC samples with low Ubqln2 expression (Figure 1D).
