    Abstract:
    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. RESULTS: The AQP4 immunoreactive cells were mainly astrocytes in the brains, which were extensively distributed in the intracytoplasm. Higher expressions of AQP4 were found in the brain tumors and adjacent tissues in the patients with glioblastoma than in the normal controls (P<0.05). More AQP4 were distributed in the tumor adjacent tissues than in the tumors (P<0.05). The AQP4 was positively correlated with the extent of brain edema. CONCLUSION: AQP4 overexpress in the brain tumors and adjacent tissues, which is associated with the extent of brain edema. Cytotoxic and vasogenic edemas may coexist in the cerebral edema induced by glioblastoma.
