Title The Transcription factor NF-YA is Crucial for Neural Progenitor Maintenance during Brain Development
Organism Mus musculus
Experiment type Genome binding/occupancy profiling by high throughput sequencing
Summary In contrast to stage-specific transcription factors, the role of ubiquitous transcription factors in neuronal development remains a matter of scrutiny. Here, we demonstrated that a ubiquitous factor NF-Y is essential for neural progenitor maintenance during brain morphogenesis. Deletion of the NF-YA subunit in neural progenitors by using nestin-cre transgene in mice resulted in significant abnormalities in brain morphology, including a thinner cerebral cortex and loss of striatum during embryogenesis. Detailed analyses revealed a progressive decline in multiple neural progenitors in the cerebral cortex and ganglionic eminences, accompanied by induced apoptotic cell death and reduced cell proliferation. In neural progenitors, the NF-YA short isoform lacking exon 3 is dominant and co-expressed with cell cycle genes. ChIP-seq analysis from the cortex during early corticogenesis revealed preferential binding of NF-Y to the cell cycle genes, some of which were confirmed to be downregulated following NF-YA deletion. Notably, the NF-YA short isoform disappears and is replaced by its long isoform during neuronal differentiation. Forced expression of the NF-YA long isoform in neural progenitors resulted in a significant decline in neuronal count, possibly due to the suppression of cell proliferation. Collectively, we elucidated a critical role of the NF-YA short isoform in maintaining neural progenitors, possibly by regulating cell proliferation and apoptosis. Moreover, we identified an isoform switch in NF-YA within the neuronal lineage in vivo, which may explain the stage-specific role of NF-Y during neuronal development.
 
Overall design E13.5 mouse brain cortices were fixed, lyzed and sonicated. The lysates (input) were subjected to chromatin immunoprecipitation (ChIP) using anti-NF-YC and anti-H3K4me3 antibodies. The DNA libraries of the input and two ChIP samples were generated by Takara ThruPLEX DNA-seq Kit, and sequenced by Illumina NextSeq 2000 using P1 regent (100 cycles).
