Metabolic Regulation of Gene Expression by Histone Lysine Ã-hydroxybutyrylation [ChIP-seq]

Project description:We identified a new type of histone mark-lysine Ã-hydroxybutyrylation (Kbhb). This ketone body derived histone mark (Kbhb) was dramatically induced in livers during starvation. To charactize histopne Kbhb: 1) We mapped genomic distributions of histone Kbhb marks (H3K9bhb, H3K4bhb and H4K8bhb) by ChIP-seq in mouse liver. 2) We examined the response of histone Kbhb mark to starvation by carrying out ChIP-seq experiments for H3K9bhb in both "starved" and "fed" mouse liver. 3) We also examined differentially-expressed genes during starvation by carrying out RNA-seq experiments in both "starved" and "fed" mouse liver. By integrating analyses of ChIP-seq and RNA-seq data, we tried to get a correlation between H3K9bhb mark and gene expression in response to starvation. Sequencing was performed on the HiSeq2000 (Illumina). ChIP-seq for histone Kbhb marks in both "starved (ST)" and "fed (AL)" mouse liver cells The anti-H3K4bhb, -H3K9bhb, and -H4K8bhb antibodies were generated from PTM biolabs. The process for generating antibodies were described similarly in Cell, 2011. 146: p. 1016-1028, Mol Cell, 2015. 58(2): p. 203-15, Nat Chem Biol, 2014. 10(5): p. 365-70, except for using different immunogens.

ScRNA-seq of stromal cells in WT and LRRC15 DTR mice

Project description:KPR tumors were subcutaneously implanted in Lrrc15DTRGFPwt/wt (DTR–) or Lrrc15DTRGFPwt/ki (DTR+) mice and DT treatment was initiated in both DTR– and DTR+ mice when tumors reached a mean volume of 100-200mm3. scRNAseq of CD24-CD45- stromal cells from a total of 40 tumor-bearing animals across both DTR– and DTR+ genotypes was carried out at four different time points including 10 days post tumor implantation and immediately prior to initiation of DT treatment (IOT) (referred to as day 0) and on days 7, 14, and 21 post IOT.

Inhibitors of the histone lysine demethylase KDM1A are broadly efficacious in AML by evicting the enzyme from chromatin [ChIP-Seq]

Project description:Examine the distribution of KDM1A and the histone H3K4me2 mark on chromatin following treatment with two distinct classes of KDM1A inhibitors - an irreversible inhibitor (RN-1) and a reversible inhibitor (GSK690) 15 samples total from two treated cell lines - 9 from Kasumi-1 and 6 from SKNO-1. Controls included were input DNA isolated from the treated cells.

H3K4me1 ChIP-Seq experiment using cells from stage 15 Drosophila melanogaster embryos sorted by reporter gene activity

Project description:The aim of this study was to analyze if transcriptionally active svb loci show enrichment for H3K4me1. To capture cells where svb-related ventral enhancers are active, we FACS-sorted nuclei from stage 15 Drosophila melanogaster embryos based on the expression of different reporter genes driven by different svb enhancers. The svb_E10 enhancer drives the expression of GFP, whilst dsRed is driven by the svb_7 enhancer. The sorted nuclei were then used for ChIP with anti-H3K4me1 and anti-H3 (for normalization purposes) antibodies.

EZH2 and BCL6 cooperate to assemble CBX8-BCOR Polycomb complex to repress bivalent promoters, mediate germinal center formation and promote lymphomagenesis [RNA-seq]

Project description:EZH2 mediates the humoral immune response and drives lymphomagenesis through de novo formation of bivalent chromatin domains and critical germinal center (GC) B cell promoters. We show that such formation is dependent on the presense of BCL6 and the presence of non-canonical PRC1-BCOR complex. We observe that BCL6 and EZH2 cooperate to accelerate diffuse large B cell lymphoma (DLBCL) development and combinatorial targeting of these repressors results in enhanced anti-lymphoma activity in vitro, in vivo, and in primary human DLBCLs.
