Expression of UbcH10 in pancreatic ductal adenocarcinoma and its correlation with prognosis.

The aim of this current study was to investigate the clinicopathologic features and prognostic significance of UbcH10 in pancreatic ductal adenocarcinoma (PDA). Real-time quantitative RT-PCR was employed to examine UbcH10 expression in 20 pairs of PDA and adjacent non-cancerous tissues. In addition, UbcH10 expression was analyzed by immunohistochemistry in 94 clinicopathologically characterized PDA cases. The correlation of UbcH10 expression with patients' survival rate was assessed by Kaplan-Meier and Cox regression. Our results showed that the expression levels of UbcH10 mRNA and protein in PDA tissues were both significantly higher than those in non-cancerous tissues. Simultaneously, high expression of UbcH10 was significantly correlated with the clinical stage (p<0.001), degree of histological differentiation (p<0.001), and lymph node metastasis (p=0.001). Moreover, high expression of UbcH10 was significantly associated with poor overall survival in PDA patients. In conclusion, UbcH10 might play a positive role in tumor development and could serve as an independent predictor of poor prognosis for PDA.
