Project description:Gnotobiotic NMRI mice were colonized at birth with B. thetaiotaomicron. Mice were sacrificed at P17 or P30, cecal contents were harvested and used for transcriptional profiling. Keywords: developmental timepoints, in vivo
Project description:Investigation of the overall in vitro response of Bacteroides thetaiotaomicron to human milk oligosaccharides. Comparison with response to MM-lactose and MM-galactose (Analysis performed using as a baseline datasets GSM301635 and GSM301637 corresponding to Bacteroides thetaiotaomicron response in MM-Glucose)
Project description:Investigation of the overall in vitro response of Bacteroides thetaiotaomicron to human milk oligosaccharides. Comparison with response to MM-lactose and MM-galactose (Analysis performed using as a baseline datasets GSM301635 and GSM301637 corresponding to Bacteroides thetaiotaomicron response in MM-Glucose) In vitro transcriptional profiles of Bacteroides thetaiotaomicron obtained from biological duplicate cultures taken: (i) at middle log phase in minimal media galactose (MM-Gal) and minimal media lactose (MM-L) and (ii) at two timepoints during log phase in minimal media human milk oligosaccharides (MM-HMO).
Project description:Gene expression profiles from mouse intestinal scrapings fed with either a glucose (n=13), galactose (n=13), or lactose-containing diet (n=13) were prepared. The mice were fed the isocaloric intervention diets during the postweaning period (postnatal days PN21-PN42) and sacrificed at PN42 in the fed state. Differential gene expression analysis reveals a clear effect of galactose consumption on metabolic pathways, especially fatty acid metabolism.
