Project description:<p>Genetic risk factors for ulcerative colitis are not well understood. We performed a family-based whole exome sequencing analysis to identify potential causal mutations. In the proband, we found a heterozygous de novo mutation in the gene HSPA1L. Our results indicate that the de novo mutation in HSPA1L is associated with ulcerative colitis.</p>
Project description:The series was designed to identify the different methylated single CpGs involved in the pathophysiology of ulcerative colitis. A cohort of n=20 monozygotic twins, discordant for ulcerative colitis was selected. Illumina and Nimblegen platforms were used.
Project description:Through laser capture microdissection and microarray analysis combined with slightly modified RNA extraction and amplification. we could analyze the subtle differential expression between colon normal cell and ulcerative colitis. Keywords: Ulcerative Colitis, amplification, microdissection
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.
Project description:Ulcerative Colitis fecal samples were transplanted into IL10 deficient gnotobiotic mice. Half of the mice received a protease inhibitor cocktail in their drinking water. After 8-weeks colonization the animals were studied for colonic inflammation, and fecal samples were collected and analyzed by LC-MS3 based quantitative metaproteomics. Data from mice transplanted with two UC patients were analyzed in this dataset.
Project description:Through laser capture microdissection and microarray analysis combined with slightly modified RNA extraction and amplification. we could analyze the subtle differential expression between colon normal cell and ulcerative colitis. Experiment Overall Design: GSM87318 is control sample and GSM87319 is Ulcerative Colitis sample.
