Project description:Purposes: To investigate the epigenetic mechanism of IBS-D(Irritable Bowel Syndrome with Diarrhea) by tRF & tiRNA sequencing in intestinal biopsies of IBS-D patients and healthy volunteers Methods: Five IBS-D and five healthy volunteers were screened, and biopsies were taken under colonoscopy. Small RNA sequencing was performed on Illumina NexSeq instrument Results:If P < 0.05, fold change > 1.5 as the cutoff, there were 14 up-regulated tRFs & tiRNAs and 14 down-regulated tRFs & tiRNAs. Conclusions:There were 14 up-regulated tRFs & tiRNAs and 14 down-regulated tRFs & tiRNAs in intestinal tissues of IBS-D .

Project description:An investigation of gene expression changes in rectal biopsies from donors with IBS compared to controls to begin to understand this complex syndrome. To further investigate differences between IBS groups (constipation and diarrhoea predominant) (part1) and how IBS relates to bacterial infection (part2) with biopsies taken 6 months after Campylobacter jejuni infection. Part1: 18 Constipation predominant IBS subjects (IBS-C) and 27 diarrhoea predominant IBS subjects (IBS-D) compared to 21 healthy volunteers (HV). Part2: 21 Campylobacter jejuni infection (PIBD, PIBS, PINIBS) compared to 19 healthy volunteers (HV). PIBD = post Campylobacter infection with IBS (within 6 months) PIBS = post infection IBS (unknown time point and organism) PINIBS = post Campylobacter infection with no resulting IBS

Project description:Micro-inflammation and gut dysfunction are features of diarrhea-irritable bowel syndrome (d-IBS) patients, although the underlying interacting molecular mechanisms remain mostly unknown. Therefore, we aimed to identify critical networks and signaling pathways active in chronic diarrhea-associated inflammation. Experiment Overall Design: Healthy volunteers and d-IBS patients were studied. Jejunal biopsies were subjected to chip analysis (Affymetrix Human Genome U133 Plus 2.0 GeneChips).

Project description:IBS-D is a disease with multi-factor interaction between environment, central system, gut and gene, and its pathogenesis is relatively complex. In order to find the regulation of miRNA in the pathogenesis of IBS-D, intestinal tissue samples of IBS-D patients and healthy subjects were obtained (5 IBS-D patients,5 healthy subjects)， Changes in miRNA expression profiles were detected by high-throughput sequencing.

Project description:Transcriptional profiling of Homo sapiens inflammatory skin diseases (whole skin biospies): Psoriasis (Pso), vs Atopic Dermatitis (AD) vs Lichen planus (Li), vs Contact Eczema (KE), vs Healthy control (KO) In recent years, different genes and proteins have been highlighted as potential biomarkers for psoriasis, one of the most common inflammatory skin diseases worldwide. However, most of these markers are not psoriasis-specific but also found in other inflammatory disorders. We performed an unsupervised cluster analysis of gene expression profiles in 150 psoriasis patients and other inflammatory skin diseases (atopic dermatitis, lichen planus, contact eczema, and healthy controls). We identified a cluster of IL-17/TNFα-associated genes specifically expressed in psoriasis, among which IL-36γ was the most outstanding marker. In subsequent immunohistological analyses IL-36γ was confirmed to be expressed in psoriasis lesions only. IL-36γ peripheral blood serum levels were found to be closely associated with disease activity, and they decreased after anti-TNFα-treatment. Furthermore, IL-36γ immunohistochemistry was found to be a helpful marker in the histological differential diagnosis between psoriasis and eczema in diagnostically challenging cases. These features highlight IL-36γ as a valuable biomarker in psoriasis patients, both for diagnostic purposes and measurement of disease activity during the clinical course. Furthermore, IL-36γ might also provide a future drug target, due to its potential amplifier role in TNFα- and IL-17 pathways in psoriatic skin inflammation.
