(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) Background and Purpose The neurological course after stroke is highly variable and is determined by demographic, clinical, and genetic factors. However, other heritable factors such as epigenetic DNA methylation could play a role in neurological changes after stroke. Methods We performed a three-stage epigenome-wide association study (EWAS) to evaluate DNA methylation associated with the difference between the National Institutes of Health Stroke Scale (NIHSS) at baseline and at discharge (ΔNIHSS) in ischemic stroke patients. more...

(Submitter supplied) Previously, we conducted an epigenome-wide study of DNA methylation (~850K sites) in peripheral blood at diagnosis and during follow-up from the RISK pediatric Crohn’s disease inception cohort and data are deposited in GEO with an access number GSE112611. We further followed up this study and identified here the genetic influence on ~850K DNAm sites (mQTL) in peripheral blood as well as newly added 41 ileal biopsies. 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) Genome wide DNA methylation differences in umbilical cord blood (UCB) of preterm and term born neonates. The Illumina 450K Human DNA methylation Beadchip was used to obtain the DNA methylation profiles of 12 preterm and 12 term UCB samples across 450,000 CpGs. 2 samples were removed due to failed quality control, and BMIQ normalization was done with 11 preterm and 11 term samples.

(Submitter supplied) Epigenetic alterations may provide important insights into gene-environment interaction in inflammatory bowel disease (IBD). Here we observe epigenome-wide DNA methylation differences in 240 newly-diagnosed IBD cases and 190 controls. These include 439 differentially methylated positions (DMPs) and 5 differentially methylated regions (DMRs), which we study in detail using whole genome bisulphite sequencing. more...

(Submitter supplied) DNA methylation patterns in chronic pulmonary obstructive disease (COPD) might offer new insights into disease pathogenesis. To assess methylation profiles in the main COPD target organ, we performed an epigenome-wide association study on bronchoalveolar lavage (BAL) cells. Bronchoscopies were performed in 18 COPD subjects and 15 controls (ex- and current smokers). DNA methylation was measured with Illumina MethylationEPIC BeadChip covering >850,000 CpGs. 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) 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) Genome wide DNA methylation profiling of Crohn's disease, ulcerative colitis, and normal peripheral blood samples. The Illumina Infinium HumanMethylation450 BeadChip v1.1 was used to obtain DNA methylation profiles across 482,421 CpGs in peripheral blood samples. Samples came from 17 Crohn's disease affected, 11 ulcerative colitis affected, and 20 normal individuals. Within these samples were three twin sets discordant for Crohn's disease and three twin sets discordant for ulcerative colitis.
