(Submitter supplied) This scRNA-seq dataset of five human subjects with ulcerative colitis (derived from colonic lamina propria samples), was analyzed and published as part of a larger manuscript (Mitsialis, V et al, "“Single-Cell Analyses of Colon and Blood Reveal Distinct Immune Cell Signatures of Ulcerative Colitis and Crohn’s Disease” in Gastroenterology), which reported immune signatures of blood and intestinal tissue differentiating ulcerative colitis from Crohn's disease from non-IBD human subjects using mass cytometry as well as scRNA-seq.

(Submitter supplied) Mucosal host DNA methylation was associated with the presence of inflammation suggesting epigenetic changes in response to the microbiota. Hierarchical clustering of the microbiota indicated ten subgroups, whereas some were driven by certain Enterbacteriacae and Bacteroides keystone species, and which were associated with host genotype and DNA methylation profiles, but with little influence from the habitual diet.

(Submitter supplied) Background and aims: Mucosal abnormalities are potentially important in the primary pathogenesis of ulcerative colitis (UC). We investigated the mucosal transcriptomic expression profiles of biopsies from patients with UC and healthy controls (HC), taken from macroscopically non-inflamed tissue from the terminal ileum and three colonic locations with the objective of identifying abnormal molecules that might be involved in disease development. more...

(Submitter supplied) Ulcerative colitis is heritable disorder with variable clinical outcome but to date only less than 10% of the disease susceptibility and the disease outcome is explained by IBD (inflammatory bowel disease) associated genetic loci. This missing heritability lay fertile grounds for investigating epigenetics as possible explanation. The aims of the study were to investigate genome-wide DNA methylation of the rectal tissue in an inception cohort of UC at two time points, once at baseline (treatment naïve) and at follow-up to explore how longitudinal DNA methylation influences the disease onset, disease progression and outcome. more...

(Submitter supplied) Ulcerative colitis (UC) and Crohn’s disease (CD) are inflammatory bowel diseases (IBD) with variable, overlapping clinical features and complex pathophysiologies. To identify pathogenic processes underlying these disease subtypes, using single endoscopic pinch biopsies to estabolish 36 expression profiles, we elucidated gene expression patterns of active and inactive areas of UC and CD, and compared these to infectious colitis and healthy controls. more...

(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.

(Submitter supplied) Due to the lack of clinical, immunologic, genetic and laboratory markers to predict remission without relapse, there is no clear recommendation regarding withdrawal of therapy. Therefore, this study was to investigate if transcriptional analysis together with Cox survival analysis might be able to reveal molecular markers that are specific for remission duration and outcome. Mucosal biopsies from patients in remission, with active treatment-naïve ulcerative colitis and healthy control subjects underwent whole-transcriptome RNA-seq. more...

(Submitter supplied) Background: This study addresses whether existing specific transcriptional profiles can improve and support the current status of the definition of ulcerative colitis (UC) remission apart from the existing endoscopic, histologic, and laboratory scoring systems. For that purpose, a well-stratified UC patient population in remission was compared to active UC and control patients and was investigated by applying the next-generation technology RNA-Seq. more...
