Chromatin immunoprecipitation of mouse B3 pre-B cells and VL3 thymocytes to identify cohesin and CTCF binding sites
Ontology highlight
ABSTRACT: Identification of cohesin (Rad21) and CTCF binding sites in ~2% of the mouse genome in B3 pre-B cells stably expressing FLAG-tagged Rad21 using anti-FLAG (Sigma F3165) and anti-CTCF (Upstate 07729) antibodies
Project description:ChIP-seq for CTCF and Rad21 in 3 week old mouse brain from reciprocal BxC and CxB crosses. One biological replicate of each. Examination of CTCF and Cohesin binding sites in neonetal mouse brain
Project description:This dataset consists of ChIP-seq data from human monocytes, monocyte-derived dendritic cells as well as monocyte-derived cells that were subjected to siRNA treatment targeting CTCF or RAD21. ChIP-sequencing was done for H3K27, RAD21 and CTCF. In total, the data set includes 120 samples.
Project description:Genome-wide ChIP data of CTCF and Rad21 binding in Rag1M-bM-^HM-^R/M-bM-^HM-^R pro-B cells CTCF and Rad21 binding in Rag1M-bM-^HM-^R/M-bM-^HM-^R pro-B
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.
Project description:H3K27Ac ChIP-seq in wild type and cohesin-deficient thymocytes Rad21 was deleted in CD4+ CD8+ double positive (DP) thymocytes by crossing a Rad21 floxed allele with a Cd4-driven Cre transgene. DP positive thymocytes were FACS-sorted from control and Rad21-/- littermates, which were then used to perform chromatin immunoprecipitation for histone H3 acetylated on lysine 27 (H3K27Ac).
Project description:To determine the positions of promoters and enhancers in developing Xenopus laevis epithelial progenitors, we performed ChIPseq on the histone modifications H3K4me3 and H3K27ac. We also performed ChIPseq on the transcription factors foxj1 (in the presence or absence of rfx2), myb (in the presence or absence of multicilin), and rad21. Some embryos were harvested as wild-types; in other experiments, we injected embryos with mRNAs encoding FLAG-foxj1 (with and without rfx2 morpholino) or GFP-myb (with and without an inducible form of multicilin (mcidas-HGR)). We then isolated epithelial progenitors surgically and, when injected with multicilin, induced at mid-stage 11. We then harvested chromatin at 9 hours after induction (roughly stage 18) and performed ChIPseq using antibodies against endogenous targets (H3K4me3, H3K27ac, rad21) or protein tags (FLAG, GFP). We then sequenced these libraries, aligned the reads to the X. laevis genome (version 9.1) with bwa mem and called peaks with HOMER, using input as background.
Project description:We explored the relationship between the evolutionary dynamics of CTCF binding and the functional stability of higher order genome structures, by performing ChIP-seq experiments in closely related Mus species or strains and intersecting with Hi-C-derived topologically associating domains (TADs) and expression data. All experiments were performed in adult male liver samples in 3 biological replicates and with an input control set. We also generated RAD21 (cohesin subunit) ChIP-seq from a replicate of adult male mouse (C57BL/6J) liver to determine localization of cohesin with respect to CTCF.
Project description:This dataset consists of RNA-seq data data from human monocytes, monocyte-derived dendritic cells or monocyte-derived macrophages as well as monocyte-derived cells that were subjected to siRNA treatment targeting CTCF or RAD21. In total, it includes 63 samples.
