ABSTRACT
Objective To investigate functional role and clinical significance of the methylation in the promoter of TPAP gene in the development and progression of pancreatic cancer.Methods Surgically resected specimen from 68 patients who were pathologically diagnosed as pancreatic cancer in Changhai Hospital from July 2006 to August 2009 were collected.The methylation in the promoter of TPAP gene in tumor and nontumor adjacent tissue was detected by methylation specific PCR.Results The methylation rate of tumor and non-tumor adjacent tissue was (0.214 ± 0.057) % and (0.084 ± 0.096) %,respectively,and pancreatic cancer tissue had significantly higher methylation rate than the adjacent tissue.Hypermethylation of TPAP gene was not correlated with age,gender,tumor differentiation,lymphatic metastasis,serum CEA and CA19-9,but was positively correlated with distant metastasis.Conclusions Hypermethylation in the promoter of TPAP gene may participate in the invasion and metastasis of pancreatic cancer and the hypermethylation of the promoter is closely associated with the tumorigenesis and development of pancreatic cancer.
