Notes:
Summary Tumours of the nervous system have been induced by transplacental ENU. Until the fourth month of life the tumoural lesions appear as mixed glial proliferations or oligodendroglial foci. From the fourth month on they develop as glial micro- and macrotumours or as isomorphic and polymorphic oligodendrogliomas. The adenylate cyclase activity studied during these two distinct phases of tumour development was markedly reduced in brain tumours, independent of their cellular origin, compared with the level in the normal brain. On the other hand, the activity of the enzyme responsible for the synthesis of cyclic AMP is significantly increased during the first period of tumour development when early neoplastic proliferations are present.
