RESUMO
NeuroD, a bHLH transcription factor, is implicated in differentiation of neurons and pancreatic β cells. NeuroD-null mice die shortly after birth due to severe neonatal diabetes. To examine if there is postnatal neuronal phenotype in these mice, we rescued them from neonatal lethality by introducing a transgene encoding the mouse neuroD gene under the insulin promoter. These mice survive to adulthood but display severe neurological phenotype due to neuronal deficit in the granule layers of the cerebellum and hippocampus. We show here that NeuroD is required for these postnatally generated microneurons to undergo proper differentiation, the absence of which results in cell death.
