ABSTRACT
ObjectiveTo investigate the correlation between PTEN and p27 expression in gastric carcinoma. MethodsImmunohistochemistry was applied to examine the expression of PTEN and p27 in 49 cases of human gastric carcinoma,49 cases of tumor-side ward mucosa and 13 cases of normal gastric mucosa.ResultsPositive expressive rates of PTEN and p27 protein in colorectal carcinoma were 61.22 %(30/49)and 57.14 % (28/49),which were lower than those in tumor-side ward mucosa [91.84 %(45/49) and 93.88%(46/49)]and normal colorectal mucosa [100 %(13/13)and 100 %(13/13)](P< 0.05). The expression of PTEN and p27 in gastric carcinoma correlated with each other (r=0.580,P=0.005),and which were associated with degree of differentiation of carcinoma,PTNM stage and lymph node metastasis of the tumors.Conclusion The abnormal expression of PTEN and p27 participate the malignant conversion process of the gastric mucosa cell and the expression levels of PTEN and p27 protein may be used to evaluate the pathologic biology behavior of gastric carcinoma.
