Project description:We profiled gene expression in hypothalamus tissue from F2 progeny from a cross between the outbred M16 (selectively bred for rapid weight gain) and ICR (control) mouse strains. We developed a framework for reconstructing tissue-to-tissue coexpression networks between genes in hypothalamus, liver or hypothalamus tissues that are independent of networks constructed from single tissue analyses. The subnetworks we identify as specific to tissue-to-tissue interactions associate with multiple obesity-relevant biological functions like circadian rhythm, energy balance, stress response, or immune response. Keywords: Tissue profiling in a mouse F2 cross. We analyzed 308 hypothalamus samples.

Project description:Highly pathogenic avian influenza virus (HPAIV) is a permanent threat due to its capacity to cross species barriers and generate severe infections and high mortality in humans. Recent findings have highlighted the potential role of PB1-F2, a small accessory influenza protein, in the pathogenesis process mediated by HPAIV in mammals. In this study, using a recombinant H5N1 HPAIV (wt) and its PB1-F2-deleted mutant (ΔF2), we studied the effects of PB1-F2 in a chicken model. Unexpectedly, when using low inoculation dose we observed that the wt-infected chickens had a higher survival rate than the ΔF2-infected chickens, a feature that contrasts with what is usually observed in mammals. High inoculation dose had similar mortality rate for both viruses, and comparison of the bio-distribution of the two viruses indicated that the expression of PB1-F2 allows a better spreading of the virus within chicken embryos. Transcriptomic profiles of lungs and blood cells were characterized at two days post-infection in chickens inoculated with the wild type (wt) or the ΔF2 mutant viruses. In lungs, the expression of PB1-F2 during the infection induced pathways related to calcium signaling and repressed a large panel of immunological functions. In blood cells, PB1-F2 was associated to a gene signature specific for mitochondrial dysfunction and down-modulated leucocytes activation. Finally we compared the effect of PB1-F2 in lungs of chickens and mice. We identified that gene signature associated to tissue damages is a PB1-F2 feature shared by the two species; by contrast, the early inhibition of immune response mediated by PB1-F2 observed in chickens is not seen in mice. In summary, our data suggest that PB1-F2 expression deeply affect the immune host response in chickens in a way that may attenuate pathogenicity, a feature differing from what was previously observed in mammal species.

Project description:Gene transcription in epididymal fat pads was investigated in an F2 cross of 129S6 x Balb/c mice using Illumina gene expression arrays. Expression data was determined in 5 months old male mice fed a carbohydrate diet. Genotyping data for the F2 offspring used in this study can be found in the file E-MTAB-395.additional.zip under the Browse all available files link (file mouse-f2-chd-genotype.txt added 8th April 2014).

Project description:The aim of this study was to identify genes involved in the variation of the muscle glycogen content at death (estimated through the glycolytic potential, GP), a determining factor in the meat quality of chicken. The gene expression profiles of the Pectoralis major muscle were established using microarrays. We compared animals showing extreme GP values, issued from a F2 cross between Fat and Lean lines. A total of 254 genes were differentially expressed between F2 birds with low or high GP. Several of these genes were validated by qRT-PCR. For the genes with human orthologs, annotation analyses were performed and mainly revealed pathways involved in carbohydrate, fatty-acid and protein metabolism. The relationship between gene expression and meat quality has to now be validated by further e-QTL studies on the F2 population.
