Expression of Bcl-2, a programmed cell death (PCD)-suppressing molecule, and Bax, the Bcl-2 related PCD-accelerating protein was investigated in varied human brain tumors. Thirty-six cases of human brain tumors comprising 4 astrocytomas, 3 anaplastic astrocytomas, 4 glioblastomas multiforme, 5 medulloblastomas, 1 ependymoma, 2 choroid plexus papilloma, 1 ganglioglioma, 1 central neurocytoma, 4 meningotheliomatous meningiomas, 3 transitional meningiomas, 4 fibroblastic meningiomas, 3 acoustic neurinomas and 1 craniopharyngioma were analyzed for the localization of Bax and Bcl-2 proteins. No relationship between the degree of the histological malignancy and the presence of Bax or Bcl-2 proteins was found in varied human brain tumors. However, it is suggested that reduced expression of Bax protein is necessary for the malignant transformation and progression of the brain tumors, since no histologically malignant brain tumors with positive Bax protein were present. Our findings indicate that the expression pattern of Bax and Bcl-2 may reflect histogenetic difference of each type of brain tumors.
