(Submitter supplied) Blood vessel growth and remodelling are essential during embryonic development and disease pathogenesis. The diversity of endothelial cells (ECs) is transcriptionally evident and ECs undergo dynamic changes in gene expression during vessel growth and remodelling.Here, we investigated the role of the histone acetyltransferase HBO1 (KAT7), which is important for activating genes during development and histone H3 lysine 14 acetylation (H3K14ac). more...

(Submitter supplied) Differential EC enrichment of pan-AcH4 was assessed at 34 select genes, including 19 EC-enriched genes, 6 broadly expressed genes, and 9 EC-excluded genes, by pan-AcH4 (AcH4K5, AcH4K8, AcH4K12, and AcH4K16) ChIP-chip analysis on human umbilical vein endothelial cells (HUVECs) and human aortic vascular smooth muscle cells (HuAoVSMCs) with a high resolution tiling DNA microarray. Specifically, the tiling array analyzes the 50 kb genomic region upstream of transcription initiation, the intragenic regions , and 50 kb genomic region downstream of the last exon.

(Submitter supplied) To determine the role of HBO1 in EC physiology, gene expression analysis was conducted on control and HBO1 siRNA-treated HUVECs. A total of 263 differentially regulated protein-coding transcripts were detected, many of which are key for growth and angiogenesis. Additionally, many genes involved in cell cycle, cell division, and DNA replication were dysregulated. HBO1-regulated genes were verified by qRT-PCR, including those with roles in vessel tone regulation (e.g. more...

(Submitter supplied) In this study, we have used inducible and tissue-specific genetic deletion to investigate the function of HBO1 in the hematopoietic system. RNA-seq was used to examine the dependence of gene expression on the presence of HBO1(KAT7). Two different conditional expression sytems were used to induce Cre recombinase and delete a floxed allele of HBO1 in this study. This was to control for the treatement effect during Cre induction (interferon induction of Mx1-cre vs. more...

(Submitter supplied) KAT7 (HBO1) is a histone acetyltransferase required for histone H3 lysine 14 acetylation (H3K14ac) and normal levels of gene expression in hematopoietic stem and progenitor cells (HSPCs). The loss of H3K14ac was detected by western blot in whole bone marrow and by flow cytometry in specific HSPC populations. In order to determine the normal distribution of H3K14ac in the HSPC population a CUT&Tag experiment was performed using lineage negative, cKit positive Sca1 positive cells (LSK) and lineage negative, cKit positive Sca1 negative cells (progenitor cells). more...

(Submitter supplied) In the conventional model of transcriptional activation, transcription factors bind to response elements and recruit co-factors, including histone acetyltransferases. Contrary to this model, we show that the histone acetyltransferase KAT7 (HBO1/MYST2) is required genome-wide for histone H3 lysine 14 acetylation (H3K14ac). Examining neural stem cells, we found that KAT7 and H3K14ac were present not only at transcribed genes, but also at inactive genes, intergenic regions and in heterochromatin. more...

(Submitter supplied) The Bromo-domain and PHD-finger protein, BRPF3, forms a complex with HBO1 and regulates the initiation of DNA replication. BRPF3-dependent histone H3K14 enriched in chromatin surrounding a fraction of replication origins may play an important role in origin firing. We used microarrays to evaluate whether replication defect due to the lack of BRPF3 is associated with transcriptional changes of replication genes.

(Submitter supplied) Acute myeloid leukaemia (AML) is a heterogeneous disease characterised by transcriptional dysregulation resulting in a block in differentiation and increased malignant self-renewal. Various epigenetic therapies aimed at reversing these hallmarks of AML have progressed into clinical trials, with most showing modest efficacy due to an inability to effectively eradicate leukaemia stem cells (LSC). To specifically identify novel dependencies in LSC we screened a bespoke library of small hairpin RNAs (shRNAs) targeting chromatin regulators in a unique ex vivo model of LSC. more...
