Transcription profiling of human sigmoid colon biopsies from healthy and patients with ulcerative colitis

Project description:Gene expression profiles were performed to compare the difference in sigmoid colon biopsies between from healthy control and patients with ulcerative colitis. Experiment Overall Design: Total RNA was isolated sigmoid biopdy from 5 healthy and 6 UC patients. Pooled 5 ug total RNA equally for each group was used and followed the Affymetrix standard protocol for microarray.

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.

Efficacy and safety of ustekinumab treatment in patients with ulcerative colitis

Project description:UNIFI was a randomized placebo-controlled phase 3 clinical trial evaluating the efficacy and safety of ustekinumab (ClinicalTrials.gov Identifier: NCT02407236). Gene expression profiling by microarrays was carried out at baseline on biopsies from the sigmoid colon (15-20cm from anal verge) of patients (n=550) with moderate-to-severe ulcerative colitis and of healthy subjects (n=18). Ulcerative colitis patients received placebo (n=186) or ustekinumab (n=364). The effects of two different dosages were investigated: 130mg (n=180) and 6mg/kg (n=184).

Gene expression patterns of biopsies from a colonoscopy taken in 2009 of an ulcerative colitis patient infected with Trichuris trichiura

Project description:Helminth infection may have the potential to suppress intestinal inflammation in inflammatory bowel diseases. Ulcerative colitis is more common in developed countries than in developing countries endemic for helminth infections. There are animal models, as well as clinical trials, suggesting therapeutic effects of experimental helminth infection. Here, we provide a comprehensive molecular portrait of dynamic changes in the intestinal mucosa of an individual who infected himself with Trichuris trichiura to treat his symptoms of ulcerative colitis. Genes involved in carbohydrate and lipid metabolism were upregulated in helminth-colonized tissue, while tissues with active colitis showed upregulation of proinflammatory genes such as IL-17, IL13RA2, and CHI3L1. T. trichiura colonization of the intestine may reduce symptomatic colitis by promoting goblet cell hyperplasia and mucus production through TH2 cytokines and IL-22. By better understanding the physiological effects of helminth infection, new therapies for ulcerative colitis could be identified. This is the third (out of three) series of arrays from this patient from a colonoscopy in 2009 when the patient was in remission. We analyzed 12 HEEBO arrays on which were hybridized RNA amplified from pinch biopsies collected from different regions of the colon. 4 samples were from the ascending colon, which was colonized by worms at the time. 3 samples were from the transverse colon, which appeared normal at the time. 3 samples were from the recto-sigmoid colon, which had recovered from colitis at the time. 2 samples were from the terminal ileum, which was unaffected by worms or colitis.

We analyzed 12 HEEBO arrays on which were hybridized RNA amplified from pinch biopsies collected from different regions of the colon. 4 samples were from the ascending colon, which was colonized by worms at the time. 4 samples were from the transverse colon, which was no longer colonized by worms at the time. 4 samples were from the recto-sigmoid colon, which was suffering from severe colitis at the time.
