Abstract:
Objective To investigate the expression and clinical significance of zinc finger protein 217 (ZNF217)in human pancreatic cancer.Methods 43 cases with pancreatic cancer undergoing surgery in the PLA 117 Hospital and People's Hospital of Ruian City from Apr .2011 to May.2014 were enrolled in the study . The pancreatic cancer and the corresponding tumor-adjacent tissues were collected .Real-time quantitative PCR (qRT-PCR)was applied to detect ZNF217 mRNA expression in pancreatic cancer (n=43)and the corresponding tumor-adjacent normal tissues.The protein expression of ZNF217 was measured by immunohistochemistry(IHC). The relationship between the expression of ZNF 217 and clinical features was analyzed by pearson chi-square test . Results The expression level of ZNF217 mRNA and protein was significantly higher in pancreatic cancer tissues than in adjacent normal tissues(P<0.05).The high expression of ZNF217 protein was positively correlated with perineural invasion, tumor size, lymphatic metastasis and advanced TNM stage (P<0.05).Conclusions The expression of ZNF217 is significantly higher in pancreatic cancer tissues than in tumor-adjacent normal tissues , and the upregulation of ZNF 217 is associated with clinicopathological features of tumor malignance .ZNF217 may become a new marker and effective therapeutic target in early diagnosis of pancreatic cancer .
