Transcriptional profiling of intestinal tissue samples from germ-free and conventionally raised mice which are either wild-type or Myd88-/-

ABSTRACT: Whole-transcriptome survey of gene expression differences between germ-free (GF) and conventionally raised (CONV-R) mice. To assess the role of toll-like receptor signalling, both wild-type and Myd88 -/- mice were used. Four different tissues were harvested from 20 mice (5 WT CONV-R, 5 Myd88 -/- CONV-R, 4 WT GF, 6 Myd88 -/- GF) and expression profiles were determines using the Affymetrix Mouse Gene 1.0ST platform. 77 samples remained after quality control.

<h4>Background</h4>The gut microbiota has profound effects on host physiology but local host-microbial interactions in the gut are only poorly characterised and are likely to vary from the sparsely colonised duodenum to the densely colonised colon. Microorganisms are recognised by pattern recognition receptors such as Toll-like receptors, which signal through the adaptor molecule MyD88.<h4>Methods</h4>To identify host responses induced by gut microbiota along the length of the gut and whether th ...[more]

Transcription profiling of mouse myocardium from gnotobiotic wild-type and Ppara-/- animals

Project description:Germ free (GF) and conventionalized (CONV-D) wild-type C57Bl/6 male mice in the CARB-fed, 24h fasted, and 30d trained states; plus GF and CONV-D CARB-fed Ppara-/- mice. CARB-fed indicates a standard polysaccharide-rich mouse chow diet. CONV-D mice are those that received a microbiota transplant from conventionally raised mice 2-3 weeks before experiment was initiated Experiment Overall Design: Hearts from six to ten week-old GF and CONV-D mice, from the following eight treatment groups (GF, CONV-D) X (CARB-fed [wild-type], 24h fast [wild-type], 30d trained [wild-type], Ppara-/- [CARB-fed])

Impact of gut microbiota on m6A/m epitranscriptomic mRNA modification in different host tissues

Project description:In this study we performed MeRIP-Seq to study N6-methyl adenosine (m6A) and and N6,2′ -O-dimethyladenosine (m6Am) modification of mRNA. We investigated the effect of the microbiota on the transcriptome and epitranscriptomic modifications in murine liver and cecum. We compared m6A/m modification profiles in cecum of conventionally raised (CONV) and germ-free (GF) mice. We additionally included GF mice colonised with the flora of CONV mice for four weeks (ex-GF), for which show that they exhibit similar patterns of the most abundant genera of gut bacteria as CONV mice. We added mice treated with several antibiotics to deplete the gut flora (abx)and vancomycin treated mice in which the genera Akkermansia, Escherichia/Shigella and Lactobacillus were enriched. Furthermore, we included GF mice colonised with the commensal bacterium Akkermansia muciniphila (Am), Lactobacillus plantarum (Lp) and Escherichia coli Nissle (Ec) and analysed their m6A/m modification profiles. In addition, we analysed changes in m6A/m- modified liver RNA for CONV, GF, and Am, Lp and Ec mice.

Germfree C57BL/6J mice are resistant to high fat diet-induced insulin resistance and have altered cholesterol metabolism

Project description:Germfree (GF) mice have been used as a model to study the contribution of the intestinal microbiota to metabolic energy balance of the host. Despite a wealth of knowledge accumulated since the 1940’s, the response of GF mice to a high fat diet is largely unknown. In the present study, we compared the metabolic consequences of a high fat (HF) diet on GF and conventional (Conv) C57BL/6J mice. As expected, Conv mice developed obesity and glucose intolerance with a HF diet. In contrast, GF mice remained lean and resisted the HF diet-induced insulin resistance. The anti-obesity phenotype of GF/HF mice was accompanied by reduced caloric intake, diminished food efficiency, and excessive fecal lipid excretion contributed to the reduced food efficiency. In addition, HF diet-induced hypercholesterolemia was ameliorated, which was partially due to an increase in fecal cholesterol excretion. However, hepatic cholesterols were increased in GF/HF mice. Elevated nuclear SREBP2 proteins and the up-regulation of cholesterol biosynthesis genes support the increased liver cholesterol biosynthesis in GF/HF mice. The resistance to HF diet-induced metabolic abnormalities in GF mice was also associated with a reduced immune response, indicated by low plasma pro-inflammatory and anti-inflammatory markers. These data suggest that the gut microbiota of Conv mice contributes to HF diet-induced obesity, insulin resistance, dyslipidemia and hepatic steatosis in mice. Thus, results of the present study describe the metabolic responses of GF mice to a HF diet and further our understandings of the relationship between the gut microbiota and the host.

Expression data from splenocytes - Wild type Myd88 or mutated MYD88-L252P mice

Project description:The MYD88 L265P mutation, activator of NF-kappa B (NF-kB), is found in 80% to 90% of WM. So far, there is no existing animal model for WM to evaluate the role of MYD88 activation, and the only published mouse model harboring the mouse ortholog MYD88 L252P mutation develops aggressive B-cell lymphomas in aged mice. The MYD88 L252P coding sequence was attached to YFP cDNA with an IRES sequence. This construct was flanked with loxP sites and inserted in the Rosa26 locus. The expression of MYD88 L252P protein is induced only in B cells after crossing with CD19_Cre mice.
