Project description:We demonstrated that a maternal antibiotic treatment can change intestinal development of the offspring piglets permanently by showing that maternal gestational antibiotic treatment affects intestinal development in offspring piglets for a period of at least seven weeks after the antibiotic treatment in the sows was finished. It was shown that immediately after birth the piglets from amoxicillin treated sows, showed upregulation of genes involved in processes related to ‘tight junctions’ and ‘immunoglobulins’. In addition, these piglets had significantly lower number of goblet cells. Together, this may lead to a gut wall that is more rapidly closed in piglets from amoxicillin treated sows, affecting the uptake of immunoglobulins and the intestinal development. Later in life, around weaning, gene expression and morphological data indicate that the crypts of piglets from amoxicillin treated sows deepen around weaning as an effect of the amoxicillin treatment which in combination with the upregulation of genes involved in cell cycle processes, ribosomal activity and protein degradation might imply that the intestinal development, the subsequent differentiation of cells or the timing of these processes was delayed by the maternal antibiotic treatment.

Project description:To identify the molecular markers of early pregnancy in pigs, we compared global gene expression profiles of the maternal peripheral blood in pregnant sows with the non-pregnant sows. Peripheral blood sample was collected at 14 days after insemination from the submandibular vein of pregnant and non-pregnant sows respectively, and total RNA was isolated, purified and sent for microarray analysis. This study identified 127 up-regulated and 56 down-regulated genes (FC >= 1.5 and P < 0.05) in peripheral blood from pregnant sows versus non-pregnant sows. Of the differently expressed genes, nine (including LPAR3, RXFP4, GALP, CBR1, CBR2, GPX6, USP18, LHB and NR5A1) were found to exert function related to early pregnancy processes. Seven differentially expressed genes (CHGB, USP18, VWF, LPAR3, NR5A1, PPARD, BIN1) were selected to perform qRT-PCR in the same RNA samples.The expression profiles of these genes detected by qRT-PCR were consistent with those by microarray, which confirmed the reliability of our microarray data.

Project description:Faecalibacterium prausnitzii, a major commensal bacterium in the human gut, is well known for its anti-inflammatory effects, which improve host intestinal health. Although several studies have reported that inulin, a well-known prebiotic, increases the abundance of F. prausnitzii in the intestine, the mechanism underlying this effect remains unclear. In this study, we applied liquid chromatography tandem mass spectrometry (LC-MS/MS)-based multi-omics approaches to identify biological and enzymatic mechanisms of F. prausnitzii involved in the selective digestion of inulin. An LC-MS/MS-based intracellular proteomic and metabolic profiling was performed to determine the quantitative changes in specific proteins and metabolites of F. prausnitzii when grown on inulin. Interestingly, proteomic analysis revealed that the putative proteins involved in inulin-type fructan utilization by F. prausnitzii, particularly b-fructosidase and amylosucrase were upregulated in the presence of inulin. To investigate the function of these proteins, we overexpressed bfrA and ams, genes encoding beta-fructosidase and amylosucrase, respectively, in Escherichia coli, and observed their ability to degrade fructan. In addition, the enzyme activity assay demonstrated that intracellular fructan hydrolases degrade the inulin-type fructans taken up by fructan ATP-binding cassette transporters. Furthermore, we showed that the fructose uptake activity of F. prausnitzii was enhanced by the fructose phosphotransferase system transporter when inulin was used as a carbon source.

Project description:Roseburia inulinivorans is a recently identified motile representative of the Firmicutes that contributes to butyrate formation from a variety of dietary polysaccharide substrates in the human large intestine. Microarray analysis was used here to investigate substrate-driven gene expression changes in R. inulinivorans A2-194. A cluster of fructo-oligosaccharide (FOS)/inulin utilisation genes induced during growth on inulin included one encoding a b-fructofuranosidase protein that was prominent in the proteome of inulin-grown cells. This cluster also included a 6-phosphofructokinase and an ABC transport system, while a distinct inulin-induced 1-phosphofructokinase was linked to a fructose-specific phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS II transport enzyme). Real-time PCR analysis demonstrated that the b-fructofuranosidase and adjacent ABC transport protein showed greatest induction during growth on inulin, whereas the 1-phosphofructokinase enzyme and linked PTS II transport system were most strongly up-regulated during growth on fructose, indicating that these two clusters play distinct roles in the utilization of inulin. The R. inulinivorans B-fructofuranosidase was over-expressed in E. coli and shown to hydrolyse fructans ranging from inulin down to sucrose, with greatest activity on fructo-oligosacharides. Genes induced on starch included the major extra-cellular a-amylase and two distinct a-glucanotransferases together with a gene encoding a flagellin protein. The latter response may be concerned with improving bacterial access to insoluble starch particles. RNA was purified from mid-exponential phase (OD650 = 0.4) cultures of R. inulinivorans grown on basal YCFA supplemented with a single substrate of either starch or inulin using the RNeasy RNA purification kit (Qiagen), and the mRNA component enriched using the MICROBExpress system (Ambion). The purified RNA (1 ug) was labelled by reverse transcription (Amersham), employing random nonamer extension incorporating either dCTP-Cy3 or dCTP-Cy5 dyes. In order to ensure reproducibility, and to obtain statistically significant results, the dye labelling was swapped for a second hybridisation. RNA purified from a separate biological replicate was labelled and hybridised twice in the same way.
