Quantitative Lipids study on total murine liver tissue from mice at different age

ABSTRACT: Following birth, the neonatal intestine is exposed to maternal and environmental bacteria that successively form a dense and highly dynamic intestinal microbiota. Whereas the effect of exogenous factors has been extensively investigated, endogenous, host-mediated mechanisms have remained largely unexplored. Concomitantly with microbial colonization, the liver undergoes functional transition from a hematopoietic organ to a central organ of metabolic regulation and immune surveillance. The aim of the present study was to analyze the influence of the developing hepatic function and liver metabolism on the early intestinal microbiota. Using metabolomic and microbial profiling in combination with multivariate analysis we characterized the colonization dynamics and liver metabolism in the murine gastrointestinal tract (n=6-10 per age group). We observed major age-dependent microbial and metabolic changes and identified bile acids as potent drivers of the early intestinal microbiota maturation. Consistently, oral administration of tauro-cholic acid or β-tauro-murocholic acid to newborn mice (n= 7-14 per group) accelerated postnatal microbiota maturation. Lipids in total liver tissue from healthy C57BL/6 mice at 1, 7, 14, 21, 28 and 56 day after birth was analyzed.

Transcriptional Modulation of Genes by Gut Microbiota in Germfree and Conventional Mice

Project description:To characterize the effect of microbiota on global gene expression in the distal small intestine during postnatal gut development we employed mouse models with experimental colonization by intestinal microbiota. Using microarray analysis to assess global gene expression in ileal mucosa at the critical stage of intestinal development /maturation associated with weaning, and asking how expression is affected by microbial colonization In the study presented here, preweaned and postweaned GF, SPF mouse small intestinal total RNAs were used. Also, 3-week-old gnotobiotic mouse as well as GF mouse small intestinal RNAs were used.

Altering the intestinal microbiota during a critical developmental window has lasting metabolic consequences [8_week_ileal]

Project description:Acquisition of the intestinal microbiota begins at birth, and a stable microbial community develops from a succession of key organisms. Disruption of the microbiota during maturation by low-dose antibiotic exposure can alter host metabolism and adiposity. We now show that low-dose penicillin (LDP), delivered from birth, induces metabolic alterations and affects ileal expression of genes involved in immunity. LDP that is limited to early life transiently perturbs the microbiota, which is sufficient to induce sustained effects on body composition, indicating that microbiota interactions in infancy may be critical determinants of long-term host metabolic effects. In addition, LDP enhances the effect of high-fat diet induced obesity. The growth promotion phenotype is transferrable to germ-free hosts by LDP-selected microbiota, showing that the altered microbiota, not antibiotics per se, play a causal role. These studies characterize important variables in early-life microbe-host metabolic interaction and identify several taxa consistently linked with metabolic alterations. Male mice were exposed to low-dose penicillin (6.7 mg/L), from birth. Ileums were collected at 8 weeks of age, RNA was extracted, and transcriptional differences were measured by microarray analysis.

Male and female mice were exposed to low-dose penicillin from birth. In a second experiment, microbiota from female control and LDP mice was transferred to 3-week old female germ-free mice. Livers were collected at 8 weeks of age, RNA was extracted, and transcriptional differences were measured by RNAseq.
