Project description:The entire small intestine was observed by balloon endoscopy. Biopsy specimens were taken from jejunum, ileum and colon, respectively. Four Crohn's disease patients and four healthy controls were compared.
Project description:Comparison of gene expression in macrophages from Crohn's disease patients or healthy control individuals, either unstimulated or stimulated with heat killed E. coli
Project description:As a hallmark of Crohn's disease (CD),creeping fat (CF) is intimately related to intestinal fibrosis and postoperative recurrence. It is defined as expansion of mesenteric adipose tissue envelops the diseased intestinal segment. Compared with the healthy controls, CF has enriched functions related to adipogenesis and immune response.
Project description:Comparison of PBMC transcriptional profiles in healthy subjects, patients with Crohn's Disease, and patients with Ulcerative Colitis
Project description:A feature of Crohn's disease is the extra-intestinal manifestation of creeping fat, defined as expansion of mesenteric adipose tissue around the inflamed and fibrotic ileum. In comparison to healthy controls, we found that the greatest transcriptional changes in creeping fat are functions related to immune response to bacterial products.
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.

Project description:This study investigates the presence of specific fibrosis-associated gene expression signatures in Crohn's disease patient biopsies.
