Summary: There is high risk of fetal neurodevelopmental defects in pregestational diabetes mellitus (PGDM). However, the effective mechanism of hyperglycemia-induced neurodevelopmental negative effects, including neural stem cell self-renewal and differentiation, still remains obscure. Neuropoietic cytokines have been shown to play a vital part during nervous system development and in the coordination of neurons and gliocytes. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) dysfunction might be related to a reduction of self-protective response in brain malformation induced by hyperglycemia. We therefore evaluated the role of Nrf2 and neuropoietic cytokines in fetal neurodevelopmental defects induced by PGDM and determined the mechanisms involved. Our data reveal that PGDM dramatically impairs the developmental switch of neural stem cells from neurogenesis to gliogenesis, principally under the cooperative mediation of neuropoietic cytokine CNTF and Nrf2 antioxidative signaling. This indicates that CNTF and Nrf2 could be potentially used in the prevention or therapy of neurodevelopmental defects of PGDM offspring. : Molecular Neuroscience; Developmental Neuroscience; Diabetology Subject Areas: Molecular Neuroscience, Developmental Neuroscience, Diabetology
