The result revealed that UBE2I expression was statistically positively linked to PIAS1 (Fig. 7b), NSMCE2 (Fig. 7c), SAE1 (Fig. 7d), RANBP2 (Fig. 7e), UBA2 (Fig. 7f), PIAS4 (Fig. 7g), RANGAP1 (Fig. 7h), SUMO3 (Fig. 7i), SUMO1 (Fig. 7j) or SUMO2 (Fig. 7k) expression in HCC. The gene discussed is PIAS1; the disease is hepatocellular carcinoma.
