[AQP4 expression in the brains of patients with glioblastoma and its association with brain edema].

Objective: To investigate the expression of aquaporin-4 (AQP4) in the brains of patients with glioblastoma and its association with brain edema.

Methods: Immunofluorescence cytochemistry and western blot tests were performed to detect the expression of AQP4 in the brain tumors and the adjacent tissues in 30 patients with glioblastoma. The association between AQP4 and the extent of brain edema was analysed.
