Project description:Activation of inflammatory pathways in human IBD. Leukocyte recruitment pathways including those for eosiniphils are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory eotaxin (CCL11) dependent networks would be up regulated in the colon of pediatric patients with Ulcerative Colitis (UC), and that these would regulate eosinophil recruitment to the gut. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Colon biopsy samples were obtained from UC patients at diagnosis, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, and biological networks were identified using Ingenuity software. Data suggested that a leukocyte recruitment network which includeds CCL11 is up regulated in pediatric UC at diagnosis. The degree of up regulation of these genes compared to healthy controls was remarkably conserved within the UC patient group, suggesting common mechanisms of mucosal inflammation. These experiments tested differential colon gene expression relative to these pathways in healthy and UC samples. Keywords: Single time point in UC and healthy controls. Colon RNA was isolated from biopsies obtained from UC at diagnosis and healthy controls. Samples were obtained from the most proximal affected segment of colon. Microarray experiments were performed as described in the CCHMC microarray core, and data was analyzed as described above in the summary. The '107' internal control CEL files (for batches 1,2,4,5) used for ormalization of the Sample VALUEs are also contained within this data set.

Project description:Activation of inflammatory pathways in human IBD IL-6:STAT3 pathways are activated in the affected colon in IBD. However, the functional implications of this are not known. We hypothesized that pro-inflammatory IL-6:STAT3 dependent networks would be up regulated in the colon of pediatric patients with Crohn Disease (CD) and Ulcerative Colitis (UC), and that these would regulate leukocyte survival, proliferation, and recruitment to the gut. These experiments tested differential colon gene expression relative to these pathways in healthy, CD, and UC samples. Colon biopsy samples were obtained from CD and UC patients at diagnosis, CD patients during therapy, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, and biological networks were identified using Ingenuity software. Data suggested that two IL-6:STAT3 dependent networks are up regulated in pediatric IBD both at diagnosis and during therapy which regulate leukocyte recruitment and survival. The degree of up regulation of these genes compared to healthy controls was remarkably conserved across the two CD groups and the UC groups, suggesting common mechanisms of mucosal inflammation. Colon RNA was isolated from biopsies obtained from CD at diagnosis and during therapy, UC at diagnosis, and healthy controls. Samples were obtained from the most proximal affected segment of colon. Microarray experiments were performed as described in the CCHMC microarray core, and data was analyzed as described above in the summary. The '107' internal control CEL files (for batches 1-4) used for normalization of the Sample VALUEs are linked below as supplementary files.

Project description:Colon gene expression in human IBD. The three major clinical subsets of Inflammatory Bowel Disease (IBD) include colon-only Crohn's Disease (CD), ileo-colonic CD, and Ulcerative Colitis (UC). These experiments tested differential colon gene expression in these three types of IBD, relative to healthy control samples, and the local degree of mucosal inflammation as measured by the CD Histological Index of Severity (CDHIS). Colon biopsy samples were obtained from IBD patients at diagnosis and during therapy, and healthy controls. The global pattern of gene expression was determined using GeneSpring software, with a focus upon candidate genes identified in a recent genome wide association study in pediatric onset IBD. Data suggested that two of these candidate genes are up regulated in pediatric IBD, partially influenced by local mucosal inflammation. These experiments tested differential colon gene expression in healthy, CD, and UC samples for candidate genes identified in a recent pediatric onset IBD genome wide association study. Keywords: Single time point in CD and UC and healthy controls. Colon RNA was isolated from biopsies obtained from CD and UC at diagnosis and during therapy and healthy controls. Samples were obtained from the most proximal affected segment of colon. Microarray experiments were performed as described in the CCHMC microarray core, and data was analyzed as described above in the summary.

Project description:When applying deconvolution methods to bulk RNAseq data, a limitation of most prior studies is the lack of paired scRNA-seq and bulk RNA-seq data from the same samples to serve as ground truth for deconvolution. Our UC cohort, containing matched scRNA-seq and bulk RNA-seq data therefore provided a unique opportunity. (The scRNAseq datasets have been published before [PMID: 32111252 PMID: 36129800 PMID: 36099881 PMID: 33837006 ]. Please see linked manuscript for details) We assembled a scRNA-seq dataset of 100,667 cells from 30 UC tissue samples (20 unique patients). Bulk RNA sequencing was performed on a subset of patients(14) in the single-cell RNA sequencing cohort due to tissue availability.
