Project description:We performed ChIP-seq to measure H3K9me3 levels in wild-type HeLa cells and HeLa cells lacking TASOR, MPP8, periphilin and SETDB1 generated through CRISPR/Cas9-mediated gene disruption.

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
Project description:Transcriptional response of KBM7 cells to IFN-gamma or TNF-alpha was investigated in control or cells with genetrap insertions in JAK2 or TNFRS1A, respectively. The experiment shows that, as expected, cells lacking JAK2 or TNFRS1A expression display a severly blunted response to the tested cytokines. KBM7 genetrap mutant cells stimulated with TNF-alpha and IFN-gamma Sample WT_1 corresponds with the control sample for the IFN-gamma stimulation; Sample WT_2 corresponds with the control sample for the TNF-alpha stimulation. As the expected differences between the samples was large, only single replicates were performed for each condition
Project description:Origin Recognition Complex Associated (ORCA) associates with repressive chromatin environments. We carried out H3K9me3 ChIP-seq to determine the affect of ORCA's loss on this repressive mark. Towards this end, we cultured U2OS osteosarcoma cells, performed control and ORCA knockdowns using siRNAs and then carried out H3K9me3 ChIP-seq to determine the regions in the genome which get affected upon ORCA knockdown. Examination of the levels of H3K9me3 in control and ORCA knockdown cells
Project description:We performed ChIP-seq analyses for WT, H3K9M mutant and clr4 mutant in Schizosaccharomyces pombe, and showed that H3K9me3 level was reduced to background levels across the entire genome, similar to clr4 mutant.
