Research Abstract

We revealed that the differentiation of neural precursor cells into astrocytes or neurons was delayed by OASIS or BBF2H7 deficiency. We tried to identify the target genes of transcription factors OASIS and BBF2H7. Consequently, we identified the direct target genes of OASIS in central nervous system. Further, we revealed that the acceleration of the differentiation of neural precursor cells into astrocytes by the signaling from OASIS mediated the epigenetic regulation which promoted the demethylation of the promoter region of astrocyte-specific marker genes.
