Genome-wide analysis of POLR2, CTCF, RAD21, and H3K9ac binding in N1E115 cells

Project description:Neuronal nitric oxide synthase 1 (NOS1) produces the gaseous signaling molecule nitric oxide (NO), which plays important roles in the development and function of the nervous system. The regulation of Nos1 gene expression is incompletely understood. Here, we explored the role of physiological hypoxia in the control of Nos1 transcription and the underlying mechanisms using N1E115 mouse neuroblastoma cells as a model. N1E115 cells were cultured for 3 days at high (20%) and low (4%) oxygen levels. Following the verification of upregulation of Nos1 mRNA and protein levels in response to 4% oxygen, we analyzed the genome-wide distribution of CTCF, RAD21, total and S2- or S5-phosphorylated RNA polymerase II, and the histone mark H3K9ac by chromatin immunoprecipitation-sequencing.

ChIP-seq of CTCF, RAD21, and TOP2B binding sites in three human tissue samples with hepatocellular carcinoma

Project description:The roles of topoisomerases in somatic mutagenesis in cancer are poorly understood and their DNA-binding landscape remains largely unmapped. Here we generated genome-wide DNA-binding maps of TOP2B, CTCF, and RAD21 in human hepatocellular carcinoma samples.

CTCF and Cohesin (Rad21) ChIP-seq in female mouse liver

Project description:Sequencing files provided here include mouse liver ChIP-seq for CTCF and the cohesin subunit Rad21. These files are part of a larger study ("CTCF and Cohesin link sex-biased distal regulatory elements to sex-biased gene expression in mouse liver") where we compare CTCF and cohesin binding in male and female mouse liver as well as differences in chromatin conformation (DNA looping).

ChIP-seq analysis of Rad21 binding during genome activation

Project description:The formation of a transcriptional competent zygote is a not fully understood process potentially involving changes in chromatin structure. Cohesin and CTCF are important nuclear architectural proteins that contribute to chromatin structure and gene regulation. Here we analyze the genome-wide location of Rad21 binding during zebrafish embryogenesis and show increased Rad21 binding over developmental time (2.5 hpf, 4.5 hpf , 10 hpf).

IGH analysis in pro-B cells with H3K4me3, H3K4me2, H3K9ac, H3K27me3, Pax5 and CTCF [ChIP-Seq]

Project description:VH-DJH recombination of the immunoglobulin heavy-chain (Igh) locus is temporally and spatially controlled during early B-cell development, and yet no regulatory elements other than the VH gene promoters have been identified throughout the entire 2.5-Mb VH gene cluster. Here we discovered novel regulatory sequences that are interspersed in the distal VH gene region. These conserved repeat elements were characterized by the presence of Pax5-dependent active chromatin, the binding of Pax5, E2A, CTCF and Rad21 as well as by Pax5-dependent antisense transcription in pro-B cells. The Pax5-activated intergenic repeat (PAIR) elements were no longer bound by Pax5 in pre-B and B cells consistent with the loss of antisense transcription, whereas E2A and CTCF interacted with PAIR elements throughout early B-cell development. The pro-B-cell-specific and Pax5-dependent activity of the PAIR elements suggests that they are involved in the regulation of distal VH-DJH recombination at the Igh locus. Analysis of chromatin and TF binding in rag2-/- and wt pro-B, DP T and Mature B cells. Chip-Seq of CTCF and Rad21. The provided data is in mm8 coordinates.
