Expression of PI3k/Akt protein and mRNA in 60 cases of gastric carcinoma and its significance / 重庆医学

ABSTRACT

Objective To explore the expression of phosphoinositide 3 kinase (PI3K)and Akt in gastric carcinoma tissues and the distal normal tissues,and to analyze their correlation with the clinical pathologic characteristics of gastric cancer.Methods The S-P immunohistochemistry and RT-PCR were used to detect the expression of PI3K and Akt protein and mRNA in 60 cases of gastric carcinoma tissues and 25 cases of normal gastric mucosal tissues.Results The expression of PI3K and Akt in the gastric carcinoma tissues was significantly higher than that in the distal normal gastric tissues with statistical difference (P <0.05)and their expression in gastric carcinoma tissues was significantly related with the pathologic differentiation degree,TNM stage,invasion depth and lymph node metastasis (P <0.05).Conclusion PI3k/Akt protein and mRNA participate in the occurrence,development, infiltration and metastasis process of gastric cancer,and play an important role in the canceration of gastric carcinoma.
