The role of FoxJ2 in the migration of human glioma cells

Previous studies have demonstrated that FoxJ2 (forkhead box J2) is a member of Forkhead Box transcription factors and acts as an important prognostic indicator in human breast cancer. Our study aimed to assess the expression and function in human glioma. Western blot analysis and immunohistochemistry were performed in human glioma tissues. Low FoxJ2 expression was observed in 80 samples and its level was correlated with the grade of malignancy. A strongly positive correlation was observed between FoxJ2 and E-cadherin. Overexpression of FoxJ2 increased E-cadherin expression and decreased vimentin expression. The wound healing and transwell assays showed that overexpression of FoxJ2 significantly inhibited their migration in U87 cells. Consistent with this, knockdown of FoxJ2 promoted cellular motility. In a word, FoxJ2 suppressed cell migration and invasion in glioma, which might be a potential novel molecular targeted therapy for surgery and immune treatment.
