Transcription profiling of embryonic stem cells from wild type and histone deacetylase 1 (HDAC1) knock out mice to identify putative HDAC1 target genes.

Project description:Histone deacetylase 1 (HDAC1) is an enzyme that promotes deacetylation of acetylated lysine residues in histones and other proteins. Histone acetylation is often associated with gene activation and expression. Los of HDAC1 leads to severe problems in development and proliferation. Moreover, it seems to be the major histone deacetylase in mouse embryonic stem cells. We used microarrays to identify putative HDAC1 target genes. Experiment Overall Design: Wild type and HDAC1 mouse embryonic stem cell, originating from same litter, were used for RNA extraction and hybridization on Affymetrix microarrays.

Class I histone deacetylases HDAC1, 2 and 3 are histone decrotonylases

Project description:We characterize histone crotonylation in intestinal epithelium-derived cells through Mass spectrometry, ChIp-Seq and RNA-Seq approaches and show that this modification is removed by class I histone deacetylases, HDAC1, 2 and 3.

Role of Histone H3 Lysine 27 Crotonylation in Gene Transcriptional Repression

Project description:Histone lysine acetylation and methylation regulate gene transcription through coordination of chromatin structure and transcriptional activity. However, our understanding of the role of histones in gene regulation is far from complete, in part due to newly discovered novel histone modifications, whose functions are yet to be uncovered1. Here we report that histone H3 lysine 27 crotonylation (H3K27cr) is selectively recognized by the YEATS domain of GAS41 in association with SIN3a-HDAC1/2 co-repressor complex for gene transcriptional repression. The GAS41 YEATS domain dimer binds proto-oncogenic transcription factor c-Myc, which recruits GAS41/SIN3a-HDAC1/2 complex to target gene loci in chromatin such as cell cycle inhibitor p21. Transcriptional de-repression of p21, directed by tumor suppressor p53 upon doxorubicin stimulation, entails dissociation of c-Myc/GAS41/SIN3a-HDAC1/2 complex from chromatin, reduced H3K27 crotonylation, and consequentially increased H3K27 acetylation at p21 locus. GAS41 knockout or H3K27cr binding depletion with CRISPR/Cas9 results in p21 activation, cell cycle arrest and tumor growth inhibition in mice. Our study explains mechanistically causal effect of GAS41 and c-Myc gene amplification on down-regulation of p21 in human colorectal cancer, and suggests GAS41 as an anti-cancer target. We propose that H3K27 crotonylation represents a previously unrecognized, distinct chromatin state for gene transcriptional repression in contrast to H3K27 trimethylation for long-term transcriptional silencing and H3K27 acetylation for transcriptional activation.

Histone crotonylation promotes endoderm differentiation. [scRNA-Seq]

Project description:In this study we report that histone crotonylation promotes human embryonic stem cell differentiation to endoderm cells. Addition of crotonate, a precursor for crotonyl-CoA and therefore histone crotonylation, dramatically enhanced endoderm cell differentiation from human embryonic stem cells, while incubation of acetate, a precursor of acetyl-CoA and therefore histone acetylation, did not change the efficiency of endoderm differentiation.

Mechanisms of Ikaros Tumor Suppression with HDAC1 through distinct histone markers in Pre-B ALL Leukemia

Project description:Ikaros functions as a master regulator of lymphocyte differentiation and a tumor suppressor. Ikaros binds DNA and regulates gene expression by chromatin remodeling. Mechanisms of Ikaros-mediated tumor suppression are unknown. Here we examined genome-wide occupancy of Ikaros and histone deacetylase 1 (HDAC1) and Histone midificaition markers in human leukemia, and found that the Ikaros and HDAC1 showed similar binding partern and HDAC1âDNA interactions are associated with the presence of bivalent chromatin, and the recruitment of HDAC1 by Ikaros is associated with bivalent chromatin at Ikaros target genes. Examine the genome-wide binding of Ikaros, HDAC1, H3K9me3, H3K9ac, H3K27me3, H3K4me3 and H3K36me3 in Nalm6 ALL leukemia cells.

Identification of 67 histone marks and histone lysine crotonylation as a new type of histone modification

Project description:We report the identification of 67 previously undescribed histone modifications, increasing the current number of known histone marks by about 70%. We further investigated one of the marks, lysine crotonylation (Kcr), confirming that it represents an evolutionarily-conserved histone posttranslational modification. The unique structure and genomic localization of histone Kcr suggest that it is mechanistically and functionally different from histone lysine acetylation (Kac). Specifically, in both human somatic and mouse male germ cell genomes, histone Kcr marks either active promoters or potential enhancers. In male germinal cells immediately following meiosis, Kcr is enriched on sex chromosomes and specifically marks testis-specific genes, including a significant proportion of X-linked genes that escape sex chromosome inactivation in haploid cells. These results therefore dramatically extend the repertoire of histone PTM sites and designate Kcr as a specific mark of active sex chromosome-linked genes in postmeiotic male germ cells. 2 histone marks (pan-lysine acetylation and pan-lysine crotonylation) were studied in 1 human cell type and 2 mouse cell types using ChIP-Seq. Input was sequenced for each cell type as a control. Pan-anti_Kac and pan-anti_Kcr antibodies were custom developed with PTM BioLab, Co., Ltd (Chicago, IL).

Genome-wide maps of histone crotonylation in pluripotent and endoderm cells. [ChIP-Seq]

Project description:We examined the genome-wide distribution of histone crotonylation and H3K27ac in human embryonic stem cells and induced endoderm cells, by obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA. When compared to H3K27ac, histone crotonylation was more enriched in metabolic genes and in promoters at pluripotent state, while H3k27ac was enriched in the enhancers of endoderm genes. After endoderm differentiation, histone crotonylation and H3K27ac were both enriched in endoderm genes. Moreover, the enrichment of histone crotonylation was more remarkable than that of H3K27ac. Our data indicate that histone crotonylation correlates with endoderm differentiation.
