Project description:Using Nanostring technology and comparative bioinformatics, we analyzed the expression of 760 fibrosis-related genes in 36 ileal surgical specimens, 12 B2(Penetrating) and 24 B3(structuring), the latter including 12 cases with associated stricture(s) (B3s) and 12 without (B3o).

Relating the transcriptome and microbiome by paired terminal ileal Crohn's disease

Project description:Management of terminal ileal Crohn's disease (CD) is difficult due to fibrotic prognosis and failure to achieve mucosal healing. A limited number of synchronous analyses have been conducted on the transcriptome and microbiome in unpaired terminal ileum tissues. Therefore, our study focused on the transcriptome and mucosal microbiome in terminal ileal tissues of CD patients with the aim of determining the role of cross-talk between the microbiome and transcriptome in the pathogenesis of terminal ileal CD. Mucosa-attached microbial communities were significantly associated with segmental inflammation status. Interaction-related transcription factors (TFs) are the panel nodes for crosstalk between the gene patterns and microbiome for terminal ileal CD. The transcriptome and microbiome in terminal ileal CD can be different related to local inflammatory status, and specific differentially expressed genes (DEGs) may be targeted for mucosal healing. TFs connect gene patterns with the microbiome by reflecting environmental stimuli and signals from microbiota.

Differential early pathogenic changes in human ileal gene expression in Crohn's disease and ulcerative colitis

Project description:The aim of this study is to identify early pathogenic changes in ileal gene expression that precede the development of macroscopic disease in inflammatory bowel diseases (IBDs). We focused on two IBD phenotypes that were unlikely to overlap: 1) ileal Crohn‚Äôs disease (CD) patients undergoing initial ileocolic resection of diseased ileum; and 2) ulcerative colitis (UC) patients undergoing total colectomy. The Control patients were those patients without IBD undergoing initial right hemicolectomy or total colectomy. In order to identify early pathogenic changes in the human ileum in inflammatory bowel diseases, we analyzed 99 two-color whole human genome expression profiles (Agilent 4410A) of a test human ileal cRNA probe vs. a common reference human ileal RNA from a Control patient (N17). A minimum of four biopsies were taken from the macroscopically disease-unaffected proximal ileal margin of freshly resected specimens from 47 ileal Crohn's disease patients undergoing initial ileocolic resection, 27 ulcerative colitis patients undergoing total colectomy and 25 Control patients undergoing either right hemicolectomy or total colectomy. The test and common reference probes were synthesized using the Agilent Low Input Linear Amplification Kit. Hybridization was carried out in DNA hybridization chambers, washed and scanned on an Axon GenePix 4000B scanner. The preprocessing, filtering and normalization of the array data was carried out using the R package LIMMA.

Transcriptomic profile of intestinal epithelial cells obtained from ileal endoscopic biopsies from newly-diagnosed, pediatric Crohn's disease patients and healthy controls.

Project description:Purpose: To uncover differentially-regulated transcripts and pathways/biological processes in newly-diagnosed, pediatric Crohn's disease in comparison to healthy controls. Methods: Intestinal epithelial cells were dissociated from ileal endoscopic biopsies, and stored at -80C in RNAlater. The polyA RNA fraction was purified, and single-end, 50 bp reads were sequenced and aligned to the Hg19 genome using the TopHat2 aligner. Differential analysis was performed using Bioconductor packages including edgeR, where significance was defined as p<0.05 and fold change>2. Results: We obtained 15788 reasonably-expressed transcripts that were included in differential analyses. Conclusions: Our study characterizes the dysregulation of intestinal epithelial cells in treatment-naïve Crohn's disease using RNA sequencing for transcriptomic profile of cells obtained through ileal endoscopic biopsies.

Project description:We report whole mRNA gene expression and Percent Spliced In (PSI) estimates for rectal (n=59) and ileal (n=60) tissue samples of 33 patients with either Crohn's disease (n=19) or ulcerative colitis (n=14)

Targeted ileal transcriptomic analysis in paediatric IBDs.

Project description:We employed contemporary targeted autoimmune RNA sequencing (HTG molecular diagnostics, Autoimmune panel) to ileal tissue derived from 96 paediatric IBD, Crohn's disease, Ulcerative colitis patients and controls. Weighted-gene-co-expression-network-analysis (WGCNA) was performed and differentially expressed genes (DEGs) were determined. We integrated clinical data to determine co-expression modules associated with time to relapse.
