Gene expression data from a cohort of Chilean Ulcerative Colitis human intestinal samples

ABSTRACT: Different genes, especially cytokines, have been deregulated in the inflammatory environment of intestinal mucosa in ulcerative colitis patients. The effects of differential gene expression such as immunological factors have been described before, however, there is no evidence of alarmins deregulated by microRNAs impacting on the pathophysiology of UC. Our goal is to study deregulated genes in inflamed mucosa for microRNA pairing in a Chilean cohort of patients. We used microarrays to compare inflamed and non inflamed mucosa from chilean ulcerative colitis patients

miRNA expression data from a cohort of Chilean Ulcerative Colitis human intestinal samples

Project description:MicroRNAs have been associated with the pathogenesis of intestinal diseases such as colon cancer and are deregulated in the inflammatory environment of intestinal mucosa in UC patients. The effects of microRNAs on immunological factors have been described before, however, there is no evidence that they have an effect on alarmins that impact on the pathophysiology of UC. Our goal is to identify deregulated miRNAs to be paired with potential target mRNAs. We used microarrays to compare inflamed and non inflamed mucosa from chilean ulcerative colitis patients

Label-free quantitative proteomics of ulcerative colitis patients

Project description:Label-free quantitative proteomics for inflamed and matched normal colonic mucosa in ulcerative colitis (UC) patients was used for discovery of differential expressed proteins. Compared to normal colonic mucosa, we found that 47 upregulated proteins and 78 downregulated proteins in UC patients according to fold change ≥ 2, p ≤ 0.05. Then, we will study the potential mechanism according to differential expressed proteins

Transcription profiling of human ulcerative colitis colonic mucosa to define an ulcerative colitis preinflammatory state

Project description:The samples are a part of a study aiming at diagnosing ulcerative colitis from genome-wide gene expression analysis of the colonic mucosa. Colonic mucosal samples were collected as endoscopic pinch biopsies from ulcerative colitis patients and from control subjects. Samples with and without macroscopic signs of inflammation were collected from the patients. Experiment Overall Design: The series contain eight UC samples with macroscopic signs of inflammation, 13 UC smaples without macroscopic signs of inflammation, five control subjects.

Effects of Inflammation and 5-ASA on ex vivo cultured ulcerative colitis biopsies

Project description:To seek effects of inflammatory status and 5-aminosalicylic acid (5-ASA, mesalazine) exposure ex vivo on mRNA levels within rectal mucosal biopsies from patients with ulcerative colitis. A total of 12 biopsies were analysed, 3 biological replicates in each of 4 categories (inflamed with or without 5-ASA, non-inflamed with or without 5-ASA).

Microarray analysis of colonic mucosal biopsies from healthy controls and patients with active ulcerative colitis

Project description:Expression data was used to evaluate changes to the transcriptional signatures across the healthy and inflamed colon. A comparison between healthy controls and active ulcerative colitis signatures was also made. Mucosal biopsy specimens were harvested at four anatomical locations within the colon from healthy volunteers and patients with active ulcerative colitis. specimens were fixed in RNA later for 24 hours at room temperature and stored at -80C for a further 24 hours prior to RNA extraction and microarray analysis.

Human colon biopsies (healthy and Ulcerative Colitis) LC-MS/MS

Project description:The etiology of the inflammatory bowel diseases, including ulcerative colitis, remains incomplete, but recent findings points to the involvement of complex host-microbial interactions. We hypothesized that an analysis of the proteins on the host-microbial interacting surface, the intestinal mucosa, could reveal novel insights into the diseases. Mucosal colonic biopsies were extracted by standard colonscopy from sigmoideum from 10 ulcerative colitis patients from non-inflammed tissue and 10 controls. The biopsies were immediately following extraction snap-frozen for protein analysis and the protein content of the biopsies was characterized by high-throughput quantative gel-free proteomics.
