C.elegans treated with control or elt-2 RNAi during adulthood and exposed to E. coli or P. aeruginosa

ABSTRACT: Transcriptional profiling of adult C.elegans exposed to E.coli or to GFP-expressing P. aeruginosa (strain PA14). For P. aeruginosa exposure, worms were separated into 2 groups - fully colonized (green) or non-colonized (dark). Six conditions ( control or elt-2 RNAi ; E.coli, P. aeurginosa colonized, and P. aeurginosa non-colonized). 2-color arrrays, each sample co-hybridized with the same reference RNA sample from mixed stage C.elegans cultures Worms were either sorted using the wormsorter (WS) or were hand picked (HP) under a fluorescent stereoscope

C.elegans exposed to P. aeurigonsa: Colonized vs Non colonized animals

Project description:Transcriptional profiling of adult C.elegans exposed to E.coli or to GFP-expressing P. aeruginosa (strain PA14). For P. aeruginosa exposure, worms were separated into 2 groups - fully colonized (green) or non-colonized (dark). Three conditions (E.coli, P. aeurginosa colonized, and P. aeurginosa non-colonized). 2-color arrrays, each sample co-hybridized with the same reference RNA sample from mixed stage C.elegans cultures Each condition includes 3 biological replicates - 2 using the wormsorter (WS) to separate colonized from non-colonized and one hand picked (HP) under a fluorescent stereoscope

Transcriptional profile of C. elegans following RNAi of elt-2 [L1 stage]

Project description:We used RNA-seq to identify 162 genes that are differentially-regulated following elt-2 RNAi Whole-worm mRNA was sequenced from elt-2 RNAi- and control-fed worms. Biological triplicates were assay for each condition

Defining the Roles and Regulation of the GATA-factor ELT-2 in the C. elegans Endoderm

Project description:We identified genome-wide sites of occupancy for the intestine-specific transcription factor ELT-2 in L3-staged N2 worm by performing ELT-2 ChIP-seq on whole worms; we performed RNA-seq on L3-staged N2 whole worms To identify DNA regions of direct ELT-2 occupancy, we performed the following ChIP-seq assays 1) ELT-2 ChIP-seq on L3 staged N2 C. elegans worms; 2) H3K4me3 ChIP-seq on matched L3 staged N2 worms; 3) Mock IgG-only ChIP-seq negative control on L3 stage N2 worms. Input DNA was also sequenced for each replicate. In addition, we performed RNA-seq on two replicates of L3 N2 C. elegans worms.

Gene expression patterns of biopsies from a colonoscopy taken in 2007 of an ulcerative colitis patient infected with Trichuris trichiura

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. We analyzed 14 HEEBO arrays on which were hybridized RNA amplified from pinch biopsies collected from different regions of the colon. 3 samples were from the ascending colon, which was colonized by worms at the time. 2 samples were from the transverse colon, which was also colonized by worms at the time. 4 samples were from the sigmoid colon, which appeared normal at the time. 3 samples were from the rectum, which showed signs of proctitis and was inflamed at the time. 2 samples were from the terminal ileum, which was unaffected by worms or colitis.

By better understanding the physiological effects of helminth infection, new therapies for ulcerative colitis could be identified. This is the second (out of three) series of arrays from this patient from a colonoscopy in 2008 when the patient was suffering from severe colitis but still had worms in the ascending colon. 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.
