Project description:To investigate the extent of similarity in epigenetic programming among human, baboon and mouse PSCs, we examined genome-wide patterns of four chromatin modifications (H3K4me3, H3K9me3, H3K27me3, H3K27ac) and DNA methylation in baboon iPSC and ESCs. We show that baboon pluripotent cells (PSCs) recapitulate key molecular features of human PSCs with much greater accuracy than that found in PSCs from non-primate species. Specifically, baboon and human PSCs exhibit significantly greater conservation of gene expression patterns, higher sequence and structural homology among pluripotency factors, more equivalent genome-wide patterns of histone and DNA methylation modifications, and similar maintenance of bivalent programming of developmental genes than that found between human and non-primate PSCs.

Project description:Histone 3 Lysine 9 (H3K9) methylation is known to be associated with pericentric heterochromatin and important in genomic stability. In this study, we show that trimethylation at H3K9 (H3K9me3) is enriched in an adult neural stem cell niche- the subventricular zone (SVZ) on the walls of the lateral ventricle in both rodent and non-human primate baboon brain. Previous studies have shown that there is significant correlation between baboon and human regarding genomic similarity and brain structure, suggesting that findings in baboon are relevant to human. To understand the function of H3K9me3 in this adult neurogenic niche, we performed genome-wide analyses using ChIP-Seq (chromatin immunoprecipitation and deep-sequencing) and RNA-Seq for in vivo SVZ cells purified from baboon brain. Through integrated analyses of ChIP-Seq and RNA-Seq, we found that H3K9me3-enriched genes associated with cellular maintenance, post-transcriptional and translational modifications, signaling pathways, and DNA replication are expressed, while genes involved in axon/neuron, hepatic stellate cell, or immune-response activation are not expressed. As neurogenesis progresses in the adult SVZ, cell fate restriction is essential to direct proper lineage commitment. Our findings highlight that H3K9me3 repression in undifferentiated SVZ cells is engaged in the maintenance of cell type integrity, implicating a role for H3K9me3 as an epigenetic mechanism to control cell fate transition within this adult germinal niche. SVZ H3K9me3 ChIP-seq profile of an adult baboon subventricular zone was generated by deep sequencing with Illumina HiSeq2000
