Research Abstract

Although neurons are postmitotic cells, which completely have exited cell cycle, the expression of DNA methyltransferase 1 (DNMT1) is observed in the cells. However, the function of DNMT1 in postmitotic neurons is unclear. To address this issue, we deleted Dnmt1 gene in neurons and examined the resultant phenotype in vitro.We found that DNMT1 plays an important role in cortical development through the regulation of neurite outgrowth mediated by neurotrophic factor signaling
