(Submitter supplied) A genome-wide DNA methylation study was conducted using base resolution bisulfite sequencing for purified intestinal CD4+ cells (resected or biopsied mucosa of a terminal ileum) from 21 patients with Crohn’s disease and 12 age/sex matched controls. The sequencing data was analyzed for differentially methylated CpGs (DMCs) and differentially methylated regions (DMRs). Integration was performed with RNA-sequencing data for the same set of samples to verify the functional impact of DNA methylation changes.

(Submitter supplied) Pathological expansion of adipose tissue (AT) is supported by adipocyte precursors, termed adipose-derived stem cells (ASCs). Elucidation of mechanisms underlying ASC function may lead to therapeutic interventions to use in cell therapy treatments on Crohn’s disease patients. Using epigenome-wide association studies, we explored the impact of Crohn’s disease on the methylation signature of human ASCs

(Submitter supplied) Chronic lymphocytic leukemia (CLL) is a biologically and clinically heterogeneous disease. The somatic hypermutation status of the immunoglobulin heavy chain variable (IGHV) genes has been identified as one of the most robust prognostic markers in CLL. Patients with unmutated IGHV status (U-CLL) typically experience an inferior outcome compared to those whose clones express mutated IGHV genes (M-CLL). more...

(Submitter supplied) The genetic risk associated with rheumatoid arthritis (RA) includes genes regulating DNA methylation and many T-cells genes with a strong MHC-association, pointing to immuno-genetic mechanisms as disease triggers. We aim to identify methylation change in naive and memory CD4+T-cells and monocytes in the early stage of disease, to gain insight to disease pathology. DNA-methylation was explored using a genome wide array (DNA methylation Illumina 450K bead chip array). more...

(Submitter supplied) Genome wide DNA methylation profiling of female Crohn's disease patients versus healthy female controls. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 485,000 CpGs in peripheral blood samples. Samples included 25 healthy controls and 18 female patients with histologically confirmed CD.

(Submitter supplied) Objective The imbalance between Th17 cells and regulatory T cells in the gut of inflammatory bowel disease (IBD) patients promotes intestinal epithelial cell damage. In this scenario, T helper cell lineage commitment is accompanied by dynamic changes to the chromatin that facilitate, enforce or repress gene expression patterns and ultimately promote the induction and maintenance of dysregulated intestinal CD4 T cells. more...

(Submitter supplied) Tissue fibrosis is a serious complication of Crohn’s disease (CD) as well as of a variety of other complex, chronic pathologies. Understanding the underlying pathophysiology of tissue fibrosis is crucial for the development of tissue-specific prevention and interventional treatment strategies. To identify molecular states specific to fibrotic disease, we employed deep sequencing to define the genome-wide DNA methylome and the whole transcriptome of purified human intestinal fibrotic fibroblasts (HIFs) isolated from the colon of patients with fibrotic CD. more...

(Submitter supplied) Mouse intestinal innate immune cells have been identified as inducing Th17 cell differentiation. However, few studies have investigated innate immune cells that are involved in CD (Crohn's disiease) pathogenesis in humans. The present study aimed to identify a human intestinal lamina propria cell subset that induces Th17 cells, and to clarify its role in CD pathogenesis. Intestinal mucosa samples were obtained from patients who underwent resection of colorectal cancer or CD. more...

(Submitter supplied) We employed contemporary targeted autoimmune RNA sequencing (HTG molecular diagnostics, Autoimmune panel) to ileal tissue derived from 96 paediatric IBD, Crohn's disease, Ulcerative colitis patients and controls. Weighted-gene-co-expression-network-analysis (WGCNA) was performed and differentially expressed genes (DEGs) were determined. We integrated clinical data to determine co-expression modules associated with time to relapse.

(Submitter supplied) Crohn’s disease arises through host-environment interaction, with abnormal gene expression resulting from disturbed pathway activation or response to bacteria. Single cell RNA-sequencing of ileal tissue from 2 paediatric Crohn’s disease patients was performed, identifying populations of CD8+ effector memory T cells (CD8+ Tem), memory B-cells, monocytes, epithelial cells and plasma cells within the ileal tissue. more...

Methods:Peripheral blood CD4+ T lymphocytes samples were collected from 4 primary refractory ITP cases and 4 age-matched healthy controls, and DNA methylome profiling was performed using Illumina Human Methylation850K. Results:The DNA methylome profiling identified a total of 260 differentially methylated CpG sites mapping to 72 hypermethylated and 64 hypomethylated genes. more...

(Submitter supplied) Crohn’s disease is a relapsing inflammatory disorder with a variable clinical course. While most patients present with purely an inflammatory phenotype (B1) at diagnosis, a subgroup (~20%) rapidly progresses to complicated disease manifestations that include stricturing (B2) within 5 years. DNA methylation is a key epigenetic mechanism that can regulate gene expression and thereby influence the development and progression of complex diseases. more...

(Submitter supplied) Systemic lupus erythematosus (SLE) is a chronic-relapsing autoimmune disease of incompletely understood etiology. Recent evidence strongly supports an epigenetic contribution to the pathogenesis of lupus. To understand the extent and nature of dysregulated DNA methylation in lupus T cells, we performed a genome-wide DNA methylation study in CD4+ T cells from 12 lupus patients and 12 normal healthy controls. more...

(Submitter supplied) Chromosomal translocations are important drivers of haematological malignancies whereby proto-oncogenes are activated by juxtaposition with super-enhancers, often called super-enhancer hijacking. We analysed the epigenomic consequences of rearrangements between the enhancers of the immunoglobulin heavy chain locus (IGH) and proto-oncogene CCND1 that are common in B-cell malignancies. By integrating BLUEPRINT epigenomic data with DNA breakpoint detection, we characterised the normal chromatin landscape of the human IGH locus and its dynamics after pathological genomic rearrangement. more...
