Transcriptome analyses of in vitro exercise by EPS and adrenaline

Project description:To evaluate transcriptomic changes induced by in vitro exercise, we established two in vitro exercise models; EPS (electrical pulse stimulation and clenbuterol treatment). As for clen-buterol treatment, differentiated C2C12 myotubes were treated by 30 ng/ml clenbuterol for 1 hour and control and clenbuterol treated C2C12 myotubes were analyzed by RNA-sequencing. As for an EPS model, EPS was applied to differentiated C2C12 myotubes for 24 hours and control and EPS applied C2C12 myotubes were analyzed by RNA-sequencing.

Ascending colon-derived mucin-type O-glycans form key mucus layers encapsulating microbiota in the colon (RNA-seq)

Project description:The colon contains a dense metabolically potent microbiota. The colonic O-glycan-rich mucus has been recognized as a key barrier to prevent microbial intrusion, but how this system forms and functions remains unclear. Here, we discovered that the colon mucus is mainly forged by microbiota-dependent secretion of O-glycosylated Muc2 by goblet cells in the ascending colon, where it seamlessly encapsulates the fecal materials including the microbiota. Deletion of O-glycans in the ascending colon impaired the segregating function of the mucous coating, leading to altered structure and metabolic output of the microbiota, and transcriptional homeostasis of the entire host mucosa. These findings represent a paradigm change of the prevailing model of the colon mucus system and provides new insights into host and microbiota symbiosis.

A long noncoding RNA lincRNA-EPS acts as a transcriptional brake to restrain inflammation

Project description:LincRNA-EPS is a long noncoding RNA that is expressed in macrophages and downregulated upon exposure to diverse microbial products. Analysis of macrophages from lincRNA-EPS-deficient mice revealed a specific role for this lincRNA in restraining immune response gene (IRG) expression. Mechanistically, lincRNA-EPS associates with chromatin at regulatory regions of IRGs to repress their transcription. To gain insight into the molecular function of lincRNA-EPS on chromatin, we generated ATAC-Seq libraries from wildtype and lincRNA-EPS-deficient macrophages stimulated with LPS.

Gene expression changes induced in Rice (Oryza sativa) leaves following treatment with any one of the following: wild type Xoo, lipopolysaccharide (LPS) and exopolysaccaride (EPS) deficient Xoo mutant; LPS proficient but EPS deficient Xoo mutant

Project description:Lipopolysaccharide is a Microbe Associated Molecular Pattern (MAMP) that is known to induce defense responses in plants. In rice we have shown that Xoo LPS induce callose deposition, reactive oxygen production and induced resistance response. The exopolysaccaride (EPS) secreted by Xoo might be involved in supressing these defense responses. We have performed transcriptional profiling of rice leaf gene expression changes after treatment with Xoo strains BXO1003 (LPS-, EPS-), BXO1002 (LPS+ EPS-) and BXO43 (wild type) along with milliQ treated leaves to identify the genes that are differentially expressed. RNA was isolated from mid veins of rice leaves 15 hours after injecting them with Xoo strains BXO1003 (LPS-, EPS-), BXO1002 (EPS-), BXO43 (wild type) or milli-Q water. The rice gene expression in each of the treatment was normalized based on the gene expression in the milli-Q treatment.

Gene expression changes in the microdissected colon epithelium are similar to those of intact colon in the Il10-/- mouse model of IBD

Project description:Epithelial cells play an important role in the protection of the colon mucosa from the resident microbiota and are involved in the initiation and maintenance of intestinal inflammation. LMD is a technique that allows the extraction of specific cell types, such as colonic epithelial cells, to analyse gene expression. LMD of colon epithelial cells followed by microarray analysis could be of more value than microarray analysis of intact colon for determining which pathways are active in the colon mucosa in the early and late stages of inflammation due to increased sensitivity to changes in specific cell populations. An experiment was performed using microarray analysis of intact colon samples and microdissected colon epithelial cell samples from Il10-/- and C57BL/6J mice at 6 and 12 weeks of age to study the molecular changes that occur in early and late inflammation stages in colon epithelium of a mouse model of colitis. Results showed that intact colon and colon epithelial cell gene expression profiles were similar in terms of pathways between Il10-/- and C57BL/6J mice at 12 weeks of age and between Il10-/- mice at 12 and 6 weeks of age. More immune-related pathways were identified at 6 weeks of age in epithelial cells than intact colon. This suggests that LMD and targeting of specific cell types may be of particular use when studying the early stages of inflammation before the intestinal morphology is detectably altered, by increasing analysis sensitivity to mucosal gene expression changes. 2x2 factorial with two tissue types analysed. Two strains of mouse (Il10 knockout mouse and the background strain C57BL/6J) were sampled at 2 timepoints (6 and 12 weeks of age) and intact proximal colon and colon epithelium harvested from each mouse (6 mice per group except for group colon epithelium C57 mouse 12 weeks where only 5 samples reached quality control standards).
