Project description:This dataset contains ChIP-seq data profiling genomic binding of H3K27ac and H3K4me3 in single cell-derived control, as well as CRISPR/Cas9 induced tRNA gene deletion clones and intergenic region deletion clones in human cancer cell lines HAP1. In this study, we found a large genomic deletion of 10q23 in Cas9 modified clones and further investigate the effect of H3K27ac binding.
Project description:The HASTER promoter region is a cis-regulatory element that stabilizes the transcription of HNF1A, preventing silencing or overexpression. We have generated a mouse model where the promoter of Haster has been specifically deleted in liver (Haster loxP/loxP; AlbCre). In liver the prevailing consequence is upregulation of HNF1A. We performed HNF1A, H3K4me3 and H3K27ac ChIP-seq to assess the impact of HNF1A upregulation on the chromatin landscape of Haster KO liver.
Project description:To study the tissue-specific evolution of regulatory elements in the mammalian lineage, we created a comprehensive map of promoters and enhancers in 4 tissues of 10 mammalian species. To map in-vivo promoters and enhancers, we performed ChIP-seq experiments for H3K4me3, H3K27ac and H3K4me1 in adult liver, muscle, brain and testis of all 10 species. The species included in the study are: macaque, marmoset, mouse, rat, rabbit, pig, dog, cat, horse and opossum. To correlate regulatory evolution to expression, we also performed RNA-seq experiments in all tissues and species submitted separately to ArrayExpress.
Project description:Considered as fundamental epigenetic regulators controlling many key cellular processes, histone modifications are a well-conserved and widely studied class of epigenetic modifications. Genome-wide studies have identified enhancers as DNA sequences that bind to H3K4me1 and H3K27ac and promoters as DNA sequences that bind to H3K4me3. To explore how the Twist1 complex (Twist1/YY1/p300) regulates miR-9 expression, we performed ChIP-seq in PLC-PRF-5 cells, providing a panorama of p300, H3K4me3, H3K4me1, and H3K27ac.
