Comparison of conventional and germ-free gastrointestinal tract

ABSTRACT: Whole tissues corresponding to the corpus, jejunum, descending colon and rectum were dissected from each mouse, washed with ice-cold PBS, placed into 2ml of RNA-later and flash-frozen in liquid nitrogen. The corpus was defined as the part of the stomach different from the antrum (distinguished by a difference in colour). The jejunum was defined as the tissue between the first 4 cm and the last 2 cm of the small intestinal tube. The descending colon and the rectum were defined as the last 3 cm of the digestive tube, where the first 2 cm was the descending colon and the last centimetre was the rectum. Keywords: other

MicroRNAomes of cattle intestinal tissues revealed possible miRNA regulated mechanisms involved in Escherichia coli O157 fecal shedding

Project description:The current study aimed to investigate whether bovine non-coding RNA play a role in regulating E. coli O157 shedding through studying miRNAomes of the whole gastrointestinal tract including duodenum, proximal jejunum, distal jejunum, cecum, spiral colon, descending colon and rectum. The number of miRNAs detected in each intestinal region ranged from 390 ± 13 to 413 ± 49. Compared between SS and NS, the number of differentially expressed (DE) miRNAs ranged from one to eight, and through the whole gut, seven miRNAs were up-regulated and seven were down-regulated in SS. The distal jejunum and rectum were the regions where the most DE miRNAs were identified (8 and 7, respectively). Functional analysis indicated that the bta-miR-378b, bta-miR-2284j and bta-miR-2284d which were down-regulated in both distal jejunum and rectum of SS, the bta-miR-2887 which was down-regulated in rectum of SS, as well as the bta-miR-211 and bta-miR-29d-3p which were up-regulated in rectum of SS were potentially regulatory to host immune functions, including hematological system development and immune cell trafficking. Our findings suggest that the alternation of miRNA expression in the gut of SS may lead to differential regulation in immune functions involved in E. coli O157 super-shedding in cattle.

Host mechanisms potentially associated with foodborne pathogen Escherichia coli O157 shedding in feedlot beef cattle

Project description:Cattle shedding > 10e4 CFU of Escherichia coli O157 per g of feces are defined as super-shedders. RNA-sequencing was performed to identify the transcriptome of tissues, including duodenum, proximal jejunum, distal jejunum, distal jejunum, cecum, spiral colon and descending colon of super-shedder cattle in comparison with non-shedders. The total number of genes detected in gut tissues ranged from 16,846 ± 639 (cecum) to 18,137 ± 696 (distal jejunum), and immune functions were enriched for the transcriptomes of small intestinal tissues, reflecting their greater immune activity than large intestine. Totally 351 differentially expression genes were identified between super-shedders and non-shedders, including 101 up-regulated and 250 down-regulated in super-shedders. Differential gene expression analysis suggested increased T-cell responses and cholesterol absorption in distal jejunum and descending colon, and inhibited B-cell maturation in intestines of super-shedders. distal jejunum of super-shedders. Our findings suggested that host genetics and E. coli O157 activities are involved in super-shedding phenomenon.

Characterization of Guca2a expressing cells in the mouse intestine

Project description:We report here the transcriptome of sorted cells from a Guca2a promoter GFP mouse model, positve and negative cells for GFP from 4 different regions of the GI tract, duodenum (top 3cm), jejunum (intermediate small intestine), ileum (bottom 10 cm) and colon +rectum from 3 different mice. This data allows the characterization of the cells expressing Guca2a at the trancriptome level, revealling expression of different cell markers and showing diversity of Guca2a producing cells along the GI tract.

Peptidomics profiling of human intestine

Project description:The aim of the project is to generate a peptidomics map of gut hormone peptides along the gastrointestinal tract, starting with the stomach and including the duodenum, jejunum, ileum, ascending colon, sigmoid colon and rectum. The tissues would be collected after surgery and the peptide fraction extracted and anlysed by nano LC-MS to identify what peptide hormones are present. These data will then be used to compare against the human transcriptome, and also for comparison against equivent peptides from murine intestinal extracts.

Differentiating Mouse Colon and Rectum: Transcriptional Differences and Environmental Exposure

Project description:We have demonstrated that the colon and rectum are transcriptionally distinct in mice and that the colon can be differentiated from rectum based on microarray profiles. This transition occurs over the first weeks of life, indicating environmental exposure is an important mediator.
