ABSTRACT
Objective To investigate the expression of DNMT3b and its correlation with clinicopathological parameters of pancreatic cancer.Methods The expressions of DNMT3b protein in 12 pancreatic cancer tissues and para-cancerous tissues were detected by Western blot.The expressions of DNMT3b protein in 59 pancreatic cancer tissues were detected by immunohistochemistry.The association of DNMT3b expression and clinicopathological parameters of pancreatic carcinoma were analyzed.Results Western blot results showed the expressions of DNMT3b protein in pancreatic cancer tissues and para-cancerous tissues were 0.69 ±0.13and 0.14 ±0.03,and the protein level of DNMT3b in pancreatic cancer tissues were significantly higher than that in para-cancerous tissues (t =4.464,P <0.05 ).Immunohistochemistry examination showed that the positive rates of DNMT3b protein were 59% in pancreatic cancer tissues and negative in para-cancerous tissues.DNMT3b expression was positively correlated with the TNM stage and lymph node metastasis.Conclusions DNMT3b is highly expressed in pancreatic cancer tissues,and it is related with malignant biological behaviors of pancreatic cancer cells.
