Project description:The whole-genome oligonucleotide microarray analysis of peripheral blood samples can contribute to the determination of distant blood markers of local pathophysiological alterations in colorectal diseases. These markers can lead to alternative screening procedures. Total RNA was extracted from peripheral blood samples of patients with Ulcerative colitis (UC) and Crohn's disease (CD) and hybridized on Affymetrix HGU133 Plus 2.0 microarrays
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: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.

Total RNA obtained from intestinal biopsies were analyzed using whole-genome microarrays.
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:Peripheral blood-derived macrophages were stimulated with viral-like particles isolated from colonic resections from patients with Crohn's disease (CD), ulcerative colitis (UC), or non-IBD controls diagnoses. RNAseq was performed to unbiasedly assess the transcriptional responses to these stimuli and revealed highly divergent macrophage transcriptional programs in response to non-IBD compared to IBD VLP.
Project description:To find predictive biomarkers for the development from inflammatory bowel disease unclassified (IBDU) to Crohn's disease(CD) or ulcerative colitis (UC), we performed short non-coding RNA profiling on IBDU patient samples at the time of diagnostic endoscopy.
Project description:Comparison of the human fecal proteomes from healthy control (HC), ulcerative colitis (UC), and Crohn's disease (CD) stool. Two cohorts: Cohort 1 with N=5 samples from each group (HC, UC, CD) and Cohort 2 with N=20 samples from HC, and N=10 samples each from UC and CD.

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. Bisulfite converted DNA from the 48 samples were hybridized to the Illumina Infinium HumanMethylation450 BeadChip v1.1
Project description:Our hypothesis is that in IBD patients intestinal bacteria translocation into the intra-abdominal fat depots affects adipocyte morphology and gene expression. The study aimed to study adipocyte gene expression of omental (OM) and mesenteric (MES) adipose tissue of ulcerative colitis (UC) and crohn's disease (CD). Total RNA was extracted from isolated adipocytes from omental and mesenteric adipose tissue of CD and UC patients. Microarray experiments were performed in duplicates of 4 different pools of RNAs extracted from adipocytes isolated from OM and MES of UC patients (n=5) and CD patients (n=5) respectively.
