Abstract:
Objective To investigate the expression of FRAT1 and β-catenin in human brain glioma,analyze the correlation between the expression and clinical pathological grades and the correlation of the two genes.Methods FRAT1 and β-catenin were detected by immunohistochemistry in 84 human brain glioma tissues and 6 human normal brain tissues.Results 66.7 ％ (56/84) and 77.4 ％ (65/84) of human brain glioma tissues expressed FRAT1 and β-catenin protein,whereas no FRAT1 and β-catenin protein expression was detected in human normal brain tissues.The expression levels of FRAT1 and ββ-catenin increased markedly with the ascending of pathologic grade of tumor specimens (r =0.55,P ＜ 0.01,r =0.70,P ＜ 0.01),there was a positive correlation between FRAT1 and β-catenin (r =0.77,P ＜ 0.01).Conclusion FRAT1 and β-catenin over-expression maybe closely related with occurrence and development of human brain gliomas.The results provide important supplements for the research of Wnt/β-catenin pathway.Meanwhile,FRAT1 may act as a valuable biomarker for molecular diagnosis of glioma and a potential target for gene therapy of glioma.
