Genome-wide gene expression analysis for target genes to differentiate patients with intestinal tuberculosis and Crohn’s disease

ABSTRACT: This study aimed at genome-wide gene expression analysis of colonic biopsies from confirmed cases of intestinal tuberculosis (ITB) and Crohn's disease (CD) in comparison to controls. Further, to evaluate the role of T regulatory cells, Foxp3 mRNA expression was quantified in serum as well as colonic biopsies of patients with intestinal tuberculosis, Crohn's disease and controls.

Genome-wide gene expression analysis for target genes to differentiate patients with intestinal tuberculosis and Crohn’s disease

Project description:This study aimed at genome-wide gene expression analysis of colonic biopsies from confirmed cases of intestinal tuberculosis (ITB) and Crohn's disease (CD) in comparison to controls. Further, to evaluate the role of T regulatory cells, Foxp3 mRNA expression was quantified in serum as well as colonic biopsies of patients with intestinal tuberculosis, Crohn's disease and controls. Paired samples, i.e. serum and colonic biopsies, were taken from 33 study subjects, which included patients with ITB and CD, and controls. RNA extraction was done and stringent quality checks performed. Human whole genome gene expression microarray analysis was performed on the Illumina HumanWG-6 Bead Chip with six total RNA samples of the 3 groups in duplicates. Real-time PCR for FOXP3 mRNA expression was analyzed in serum samples (4-CD, 5-ITB, 4-controls) and colonic biopsy samples (4-CD, 5-ITB, 4-controls).

Expression data from intestinal mucosa of patients with CD under anti-TNF-alpha therapy.

Project description:Crohn's Disease (CD) is a chronic inflammatory disease of the intestinal tract. We performed a whole-genome transcriptional analysis using colonic biopsies from CD patients before and after anti-TNF-α therapy. Involved colonic samples from Crohn's disease patients and healthy colonic samples from non-inflammatory controls were collected for RNA extraction and hybridization on Affymetrix microarrays. Inclusion criteria for CD patients were: age between 18 and 70, diagnosis of CD established at least 4 months before inclusion and exclusion of concomitant infection. Active disease was defined by endoscopic and clinical score: endoscopic active disease was defined as a CD endoscopic index of severity (CDEIS) of 5 or more and the presence of large ulcers (> 0.5 cm diameter) in at least one of the explored segments. Clinical activity was defined as a CD activity index (CDAI) above 150. Finally, a total of 39 biopsies were analyzed: 17 healthy controls, 10 active CD without anti-TNF therapy, 5 active CD with anti-TNF therapy (non-responders) and 7 inactive CD with anti-TNF therapy (responders).

Colonic miR-31 is a molecular stratifier and prognostic determinant of Crohn’s disease [adult]

Project description:The clinical course of Crohn's disease (CD) is highly heterogeneous, confounding effective personalized therapy. There is a critical need to better understand the cellular mechanisms responsible for the variability in disease presentation and response to therapeutic modalities. We carried out whole transcriptome profiling in colon tissue from adult CD patients and controls and found that CD patients segregate into the same two molecular subtypes based on mRNA, long non-coding RNA, or microRNA profiles. MicroRNA-31 (miR-31) in colonic epithelium was identified as a primary contributor to this molecular stratification. We further performed small RNA-seq on formalin-fixed paraffin embedded colon and ileum biopsies obtained at the time of diagnosis from 130 treatment-naïve pediatric CD patients and controls. Colonic expression of miR-31 in pediatric patients was identified as predictive of either medically refractory rectal CD or fibrostenotic ileal CD. Our study reveals miRNAs as important molecular stratifiers and prognostic determinants of CD subtypes.

Developing biomarkers incorporating high throughput RNA, DNA, small RNA sequencing and protein expression in Inflammatory Bowel Disease using formalin-fixed, paraffin-embedded (FFPE) tissue samples.

Project description:This dataset includes RNA-seq data from ileal and colonic biopsies at time of diagnosis for treatment-naive, uncomplicated Crohn's disease (CD) patients and matched controls. This is includes 56 CD patients each for ileal and colonic tissue and for controls, 46 colonic samples and 45 ileal samples. Clinical characteristics such as development of complications, disease remission, or progression to surgery were recorded with a mean follow-up of 6 years.

Genome-wide analysis of Crohn's disease and ulcerative colitis biopsy samples.

Project description:Gene expression patterns of Crohn's disease (CD) and ulcerative colitis (UC) colonic specimens were analyzed using whole-genome microarrays. Healthy control samples were included in order to detect gene expression changes associated with CD or UC. CD and UC samples were also compared in order to identify the molecular mechanisms that distinguish both fenotypes of inflammatory bowel disease. Total RNA obtained from intestinal biopsies were analyzed using whole-genome microarrays.

Colon biopsies from Crohns patients and healthy controls

Project description:The aim of this study was to investigate differential intestinal gene expression in patients with Crohn's disease (CD) and controls. 172 biopsies from CD and control subjects were studied. Endoscopic biopsies were taken at ileocolonoscopy from five specific anatomical locations including the terminal ileum for RNA extraction.

Characterization of H3K4me3 histone modifications in intestinal epithelial cells among healthy controls and newly-diagnosed pediatric Crohn's disease patients.

Project description:We report profiling of H3Kme3 histone modifications in intestinal epithelial cells from ileal endoscopic biopsies obtained from healthy controls and newly-diagnosed Crohn's disease (CD). We identified 1066 shared sites, corresponding to 1038 genes with increased H3K4me3 in CD, and 539 sites corresponding to 548 genes with reduced H3K4me3 in CD.

Gene expression analysis in gut biopsies of Crohn's Disease patients and patients with Spondylarthropathy

Project description:A focussed microarray chip was constructed specifically for studying basal colonic gene expression in patients with Spondyloarthropathy (SpA) and Crohn's disease (CD) (ref: PMID 16476712). These focus microarrays were used 1) to study common changes in gene expression between SpA and CD, providing early markers in the follow-up study of patients with SpA and particularly these patients that evolve into clinically overt CD; and 2) to identify new candidate genes for CD by integrating gene expression data with genetic information. Keywords: Crohn's Disease, Spondylarthropathy, biopsies
