Project description:Analysis of miRNA expression in colon biopsies from Crohn's disease (CD), ulcerative colitis (UC), and non-inflammatory bowel disease (IBD) control subjects.
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:In Crohn's disease, creeping fat is the characteristic expansion of mesenteric adipose tissue wrapping around the inflamed intestine. Through a comparative transcriptomic analysis of creeping fat and normal-looking mesenteric adipose tissues from patients with Crohn's disease and non-Crohn's disease, we found that a dynamic transcriptional and cell compositional change occurs during the progression from non-Crohn's disease to Crohn's disease, and finally to creeping fat.
Project description:This study investigates the presence of specific fibrosis-associated gene expression signatures in Crohn's disease patient biopsies.
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.
Project description:Histology in the mesentery pointed to altered blood vessels. This experiment was designed to define the differences in gene expression in vessels from Crohn's disease versus controls. Crohn's disease was separately evaluated in inflamed (central disease) areas and in adjacent noninflamed areas. Laser capture microdissection was carried out on Carnoy's fixed mesenteric samples, comparing normal arteries or veins with Crohn's inflamed or nonifnlamed arteries or veins.
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.
