Project description:This SuperSeries is composed of the following subset Series: GSE25275: Gene expression patterns of biopsies from a colonoscopy taken in 2007 of an ulcerative colitis patient infected with Trichuris trichiura GSE25276: Gene expression patterns of biopsies from a colonoscopy taken in 2008 of an ulcerative colitis patient infected with Trichuris trichiura GSE25277: Gene expression patterns of biopsies from a colonoscopy taken in 2009 of an ulcerative colitis patient infected with Trichuris trichiura Refer to individual Series
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 first (out of three) series of arrays from this patient from a colonoscopy in 2007 when the patient had mild proctitis in the rectum and worms in the ascending and transverse colon.

Project description:Trichuris muris is very closely related to the human parasite T. trichiura sharing cross reactive antigens. Moreover, it is a remarkably tractable model system for dissecting immune responses and host parasite relationships and is actively being investigated in a number of laboratories worldwide. T. muris is a naturally occurring nematode parasite of mice which resides in the caecum and colon and has a direct oral faecal life cycle. High-throughput sequencing of Trichuris muris transcriptome for de novo assembly of transcripts. The main objective of this project is to recognize genes expressed in given life stages. This data is part of a pre-publication release.

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.
