(Submitter supplied) To investigate whether the H3K27ac is involved in the development of inflammatory bowal disease. We established dextran sulfate sodium (DSS)-induced chronic colitis and performed RNA-sequencing and Chromatin Immunoprecipitation followed by NGS sequencing for H3K27ac in the mice colon tissues. We find that the global H3K27ac distribution in colon tissue had no significant difference, while on the typical-enhancers specific in the DSS group, H3K27ac signals were significantly enriched when compared with the control. more...

(Submitter supplied) Inflammatory bowel disease (IBD) is a multiple-genes-involved chronic disease and current available targeted drugs for IBD only deliver moderate efficacy. Whether there is a single gene that systematically regulates IBD is not yet known. Here we showed that the expression of miR-146a in colon was elevated in Dextran Sulfate Sodium Salt (DSS)-induced IBD mice and patients with IBD. DSS induced dramatic body weight loss and much more rectal bleeding, shorter colon length and colitis in miR-146a knock-out mice than wild type (WT) mice. more...

(Submitter supplied) Activation of transcription enhancers, especially super enhancers, is one of the important epigenetic features of tumorigenesis. However, only very few studies reported how the enhancer landscape evolves during tumorigensis. Here we utilized a proteomics approach and found that H3K27ac and H4K8ac are elevated in the mammary tumor of MMTV-PyVT mouse model, which was then confirmed by IHC results in human BRCA chips. more...

(Submitter supplied) The human C-type lectin Reg3a (HIP/PAP) is an antimicrobial peptide that kills Gram-positive bacteria. Reg3a preserves gut microbiota homeostasis, reinforces intestinal barrier function and thereby helps to fight induced colitis in mice. Transcriptomic data revealed an upregulation of numerous genes involved in the robustness of the intestinal barrier, and the biosynthesis pathway of mucin core 1 and 3 O-glycans.

(Submitter supplied) Inflammatory bowel disease (IBD) is a debilitating and relapsing chronic disease of the gastrointestinal tract affecting millions of people. Here, we investigated the expression and functions of poly (ADP-ribose) polymerase 14 (Parp14), an important regulator of immune cells functions, using a biobank IBD patient cohort as well as the oral dextran sulfate sodium (DSS) exposure mouse IBD colitis, and, in parallel, the oral Salmonella exposure mouse colitis models. more...

(Submitter supplied) Mucosal healing is a key treatment goal for inflammatory bowel disease, and epithelial regeneration is required for an intact gut epithelium. Long noncoding RNAs are involved in the development of inflammatory bowel disease. Here, we investigated the role of a novel long noncoding RNA, Gm31629, in epithelial regeneration. We used RNA-seq to to detail the global programme of gene expression in distal colon tissues from WT and Gm31629-/-.

(Submitter supplied) Background & Aims: The contribution of genetics to the pathogenesis of inflammatory bowel disease (IBD) has been established by twin studies, targeted sequencing and genome-wide association studies (GWASs). This has yielded a plethora of risk loci with an aim to identify causal variants. Research on the genetic components of IBD has mainly focused on protein coding genes, thereby omitting other functional elements in the human genome i.e. more...

(Submitter supplied) Temporal genome profiling of DSS colitis The DSS induced mouse colitis model is often used to emulate Ulcerative Colitis (UC) in order understand pathophysiological mechanism of inflammatory bowel disease (IBD). Given the progressive nature of IBD, colon tissue gene expression changes during the evolution of disease, and knowing the changes in gene expression profiles could indentify potential diagnostic markers or additional therapeutic targets for colitis. more...

Analysis of colon from C57BL/6J 12-14wk-olds treated with DSS for up to 6 days. DSS model emulates clinical and histopathological features of ulcerative colitis (UC), a type of Inflammatory Bowel Disease (IBD). Results provide insight into molecular mechanisms underlying development of DSS colitis.

(Submitter supplied) Huntington neurodegenerative disease (HD) is associated with extensive down-regulation of neuronal genes. We show preferential down-regulation of super-enhancer-regulated neuronal function genes in the striatum of HD mice. Striatal super-enhancers display extensive H3K27 acetylation within gene bodies and drive transcription characterized by low levels of paused RNAPII. Down-regulation of gene expression is associated with diminished H3K27 acetylation and RNAPII recruitment. more...

(Submitter supplied) We report the acetylation of lysine residues in the globular domain of H3 (H3K64ac and H3K122ac) marks active gene promoters and also a subset of active enhancers in mouse embryonic stem cells (mESCs), human erythroleukemic cell line (K562). Moreover, we find a novel class of active functional enhancers in ESCs that are marked by H3K122ac but which lack H3K27ac. This work suggests that a more complex analysis of histone acetylation is required to identify enhancers than was previously considered.

(Submitter supplied) Histone modifications are now well-established regulators of transcriptional programs that distinguish distinct cell states. However, the kinetics of histone modification and their role in mediating rapid, signal-responsive changes in gene expression have been little studied on a genome-wide scale. Vascular endothelial growth factor A (VEGF), a major regulator of angiogenesis, rapidly triggers changes in transcriptional activity of human umbilical vein endothelial cells (HUVECs). more...
