The Neurodevelopmental Hypothesis of schizophrenia suggests that interaction between genetic and environmental events occurring during critical early periods in neuronal growth may negatively influence the way by which nerve cells are laid down, differentiated and selectively culled by apoptosis. Recent advances offer insights into the regulation of brain development. The Writ family of genes plays a central role in normal brain development. Activation of the Wnt cascade leads to inactivation of glycogen synthase kinase-3beta (GSK-3beta). accumulation and activation of beta-catenin and expression of genes involved in neuronal development. Alteration in the Wnt transduction cascade. which may represent an aberrant neurodevelopment in schizophrenia. is discussed. Programmed cell death is also an essential component of normal brain development. Abnormal neuronal distribution found in schizophrenic patients' brains may imply aberrant programmed cell death. GSK-3 participates in the signal transduction cascade of upoptosis. The possible role of aberrant GSK-3 in the etiology of schizophrenia is discussed. (C) 2002 Elsevier Science B.V./ECNP.
