Project description:Gut microbiota dysbiosis characterizes systemic metabolic alteration, yet its causality is debated. To address this issue, we transplanted antibiotic-free conventional wild-type mice with either dysbiotic (“obese”) or eubiotic (“lean”) gut microbiota and fed them either a NC or a 72%HFD. We report that, on NC, obese gut microbiota transplantation reduces hepatic gluconeogenesis with decreased hepatic PEPCK activity, compared to non-transplanted mice. Of note, this phenotype is blunted in conventional NOD2KO mice. By contrast, lean microbiota transplantation did not affect hepatic gluconeogenesis. In addition, obese microbiota transplantation changed both gut microbiota and microbiome of recipient mice. Interestingly, hepatic gluconeogenesis, PEPCK and G6Pase activity were reduced even once mice transplanted with the obese gut microbiota were fed a 72%HFD, together with reduced fed glycaemia and adiposity compared to non-transplanted mice. Notably, changes in gut microbiota and microbiome induced by the transplantation were still detectable on 72%HFD. Finally, we report that obese gut microbiota transplantation may impact on hepatic metabolism and even prevent HFD-increased hepatic gluconeogenesis. Our findings may provide a new vision of gut microbiota dysbiosis, useful for a better understanding of the aetiology of metabolic diseases. all livers are from NC-fed mice only.

Project description:Total RNA versus genomic DNA hybridization on custom arrays designed for all Yarrowia lipolytica genes Total RNA was collected in mid-log phase from Yarrowia lipolytica cells grown in rich medium (abbreviated CM, in house recipe). RNA was then converted to cDNA, Cy3-labeled and hybridized competitively against Cy5 labeled genomic DNA from Yarrowia lipolytica.

Project description:Investigation of whole genome gene expression level changes in a Yarrowia lipolytica Y4184 snf1 mutant, compared to the Y4184U+. The Y4184 is an engineered strain to produce eicosapentaenoic acid (EPA) via expression of a M-NM-^T9 elongase/M-NM-^T8 desaturase pathway, and is derived from Yarrowia lipolytica ATCC#20362. A six chip study using total RNA recovered from three separate cultures of Yarrowia lipolytica Y4184Ura+ strains and three separate cultures of Y4184 snf1 mutant strains in which YlSNF1 gene is deleted entirely. Each chip measures the expression level of 6708 genes from Yarrowia lipolytica ATCC#20362 with fourteen 24-mer probe pairs (PM/MM) per gene, with three-fold technical redundancy.

Project description:In the context of replacing fish meal and fish oil in feeds for aquaculture, rainbow trout alevins received from first-feeding onwards, one of the three experimental diets: V (100% plant-based), C (mix of FM-FO & plant ingredients) or M (100% FM-FO based). The long term effects of such dietary replacement on the intestinal (mid gut) and hepatic transcriptome were studied in juveniles after a 7-month feeding trial at 7°C.
