Effects of starter microbiota on the gastric transcriptome profile of 2 weeks old caesarean derived pigs

ABSTRACT: An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization on the maturation of the porcine gastric mucosa are largely unknown. The transcriptome of the oxyntic mucosa of 12 caesarian-derived pigs previously associated with microbiota of different complexity was studied. Pigs received sow blood serum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. Then pigs were fed a moist diet . Gastric samples were obtained at on euthanised pigs at 2 weeks of age.

Effects of starter microbiota and early life feeding of medium chain triglycerides on the gastric transcriptome profile of 3 weeks old caesarean derived pigs

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization and early life feeding of medium chain triglycerides on the maturation of the porcine gastric mucosa are largely unknown. The transcriptome of the oxyntic mucosa of 24 caesarian-derived pigs previously associated with microbiota of different complexity and fed a diet fortified or not with medium chain fatty acids was studied. Pigs received pasteurized sow colostrum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. Then half of pigs was fed a moist diet (CON) or, for the remaining half, CTRL fortified in medium chain triglycerides with 7% coconut oil ( MCT). Gastric samples were obtained at on euthanised pigs at 3 weeks of age.

Early microbial colonisation affects transcriptome of pig jejunum perfused with E. coli F4, F4 fimbria or Lact. amylovorus

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization on the gut barrier upon the further encounter of favorable bacteria or not, are largely unknown. The jejunal transcriptome of differently perfused intestinal loops of 12 caesarian-derived pigs previously associated with microbiota of different complexity was studied. Pigs received pasteurized sow colostrum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. On days 26-37 of age, jejunal loops were perfused for 8 h with either enterotoxigenic E. coli F4 (ETEC), F4 fimbriae (F4), LAM or saline (CTRL) and jejunal samples were obtained from each piglet immediately afterwards.

The analysis of whole mRNA transcript expression was done by AffymetrixÂ©Porcine Gene 1.1 ST array strips, a Robust Multichip Analysis was performed on the CEL files, and Transcripts IDâs were associated to 13,406 Human gene names, based on Sus scrofa Ensemble

Differential gene expression in the oxyntic and pyloric mucosa of the young pig

Project description:The stomach is often considered a single compartment, but morphological differences among different areas are well known. Oxyntic mucosa (OXY) is primarily equipped for acid secretion, while it is not enough clear if gastric functional control are shared with other areas. We used microarrays to detail the differential gene expression related to the different gastric part in the young pig. After slaughtering OXY and pyloric (PYL) mucosa were obtained in 7 already weaned pigs.

Transcription profiling of piglet ileal tissues to assess the impact of environment on microbial diversity and global transcriptional responses in the developing gut

Project description:The study investigated the impact of environment on the composition of the gut microbiota and mucosal immune development and function at gut surfaces in early and adult life. Piglets of similar genotype were reared in indoor and outdoor environments and in an experimental isolator facility. Mucosa-adherent microbial diversity in the pig ileum was characterized by sequence analysis of 16S rRNA gene libraries. Host-specific gene responses in gut ileal tissues to differences in microbial composition were investigated using Affymetrix microarray technology and Real-time PCR. Experiment Overall Design: Animals were reared on the sow at an outdoor or indoor facility. Additional piglets from the indoor facility were transferred to individual isolator units at 24 hours of age, and given a daily dose of antibiotic cocktail for the duration of the study. Piglets were weaned at day 28. From day 29 onwards, piglets were fed creep feed ad libitum. Ileal tissue samples were excised from N=6 piglets per group at day 5, 28 and 56.

Real-time quantitative PCR analysis of jejunal and ileal mucosa from postnatal growth retardation and healthy pigs

Project description:The purpose of this study was to investigate the relative mRNA expression related to hormone, antioxidant capacity and immune responses in jejunal and ileal mucosa of healthy and postnatal growth retardation pigs. At 42 d of age, after overnight fasting, six postnatal growth retardation pigs and six healthy pigs were pair-matched by litter were selected for sampling. Samples of the jejunal and ileal mucosa were scraped and immediately snap-frozen in liquid nitrogen and stored at −80°C for RNA extraction. We used Roche LightCycler ® 480 Instrument PCR assay panel to quantitate gene expression of hormone, antioxidant capacity and immune responses relevant genes from jejunal and ileal mucosa.

Essential role of gastric gland mucin in preventing gastric cancer in mice

Project description:To elucidate the molecular mechanism by which A4gnt-null mice develop gastric adenocarcinoma, gastric mucosa was isolated from the stomachs of wild-type and A4gnt-null mice, and microarray analysis was performed. Total RNA was isolated from the gastric mucosa stripped from the muscular layer of the glandular stomach of A4gnt-null and wild-type mice at 5, 10, and 50 weeks of age (one mouse per each group was analyzed).

Transcription profiling by array of pig liver from neonatal pigs fed milk and soy formula

Project description:The majority of babies in the US are formula-fed instead of breast fed. There are major differences in the composition of formulas and breast milk and yet little is known about metabolic differences in babies as the result of feeding these very different diets and how that might affect development or disease risk in later life. One concern is that soy-based formulas might have adverse health effects in babies as a result of the presence of low levels of estrogenic phytochemicals genistein and daidzein which are normally present in soy beans. In the current study, we used a piglet model to look at this question. Piglets were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food. Blood glucose and lipids were measured. Formula-fed pigs were found to have lower cholesterol than breast fed piglets and in addition had larger stores of iron in their liver.Microarray analysis was carried out to see if changes in liver gene expression could explain these effects of formula feeding. It was found that overall gene expression profiles were influenced by formula feeding compared to breast fed neonates. Gender-independent and unique effects of formula influenced cholesterol and iron metabolism. Further, soy formula feeding in comparison to milk-based formula failed to reveal any estrogenic actions on hepatic gene expression in either male or female pigs. Piglets (female, male) were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food.
