- W3029046870 abstract "Objective To determine the expression of brain-derived neurotrophic factor (BDNF) in pancreatic ductal adenocarcinoma and its clinical significance.Methods SP immunohistochemical staining method was used to detect the expression of BDNF in 46 cases of pancreatic ductal adenocarcinoma,38 cases of benign pancreatic diseases and 20 cases of normal pancreatic tissue.Real time PCR and Western blot was used to detect the protein and mRNA expression levels.The relationship between BDNF expression and clinicopathological parameters of pancreatic cancer was determined.Results The positive expression rate of BDNF was 52.2％ (24/46) in pancreatic ductal adenocarcinoma pancreatic ductal adenocarcinoma,7.8％ (3/38) in benign pancreatic diseases,and none of the normal pancreatic tissue was BDNF positive.The BDNF protein expression levels in pancreatic ductal adenocarcinoma,benign pancreatic diseases and normal pancreatic tissue were 0.38± 0.01,0.56± 0.01,0.97± 0.01,respectively,and the BDNF mRNA expression levels were 0.85 ± 0.14,1.67 ± 0.21,3.45 ± 0.67,respectively,and the expression levels in pancreatic ductal adenocarcinoma and benign pancreatic diseases were significantly higher than that in normal pancreatic tissue,while the expression level in pancreatic ductal adenocarcinoma was significantly higher than that in benign pancreatic diseases (P ＜0.05).Positive BDNF expression was correlated with nerve infiltration and lymph node metastasis of pancreatic ductal adenocarcinoma,but it was not related to age,sex,tumor size,location and differentiated degree (P ＞ 0.05).Conclusions BDNF is involved in the development and growth of pancreatic cancer,and it may be related with patient's prognosis.Key words: Pancreatic neoplasms; Brain-derived neurotrophic factor; Neoplasm metastasis; Gene expression" @default.
