title: The expression profile of FRAT1 in human gliomas.
abstract: FRAT1 was originally characterized as a protein frequently rearranged in advanced T cell lymphoma, which inhibits GSK-3-mediated phosphorylation of beta-catenin and positively regulates the Wnt signaling pathway. FRAT1 has been identified as a proto-oncogene involved in tumorigenesis. Previous studies have shown that FRAT1 is strikingly overexpressed in some human cancers. However, the relationship between FRAT1 and human gliomas is unclear. In this study, we detected the expression of FRAT1 in human gliomas by immunohistochemistry, Western blot and RT-PCR. FRAT1 was found to be specifically expressed in the majority of glioma samples, and their expression levels increased markedly with the increase of WHO grades. In addition, there was a positive correlation between FRAT1 immunoreactivity score (IRS) and beta-catenin IRS. Our results suggest that FRAT1 may be an important factor in the tumorigenesis and progression of gliomas, and could be used as a potential molecular marker for pathological diagnosis and a target for biological therapy.
