Profiling of adipose tissue from the F2 M16xICR mouse cross.

ABSTRACT: We profiled gene expression in adipose 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, adipose or adipose 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.

Profiling of hypothalamus tissue from the F2 M16xICR mouse cross.

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.

mRNA expression in white adipose tissue of adult F2 female offspring from F0-fathers fed a chow or high-fat diet

Project description:The purpose of this study was to investigate whether paternal high-fat diet (HFD) transgenerationally remodels the epigenome of spermatozoa to alter metabolism in the F1 and F2 generation offspring White adipose tissue mRNA expression profiling of F2-female offspring from F0-founders fed either a chow or a chronic HFD challenged. Adult females were challenged or not a high-fat diet for 12 weeks. White adipose tissue was dissected at an endpoint experiment. Rats were subjected to 4 hours fasting prior to anesthesia with pentobarbital and tissue collection.

Study of PB1-F2 functions in avian host.

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.

Mouse F2 Cross, Carbohydrate Diet, Fat Tissue

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).

Expression profiling of Adipose tissue from C57BL/6J X C3H/HeJ)F2 and (C3H/HeJ X C57BL/6J )F2

Project description:The purpose of this experiment was to determine the expression traits in animals from F2 intercross of inbred strains C57BL/6J, C3H/HeJ. (N=309, 164 males and 145 females). Adipose from 295 F2 female and male mice were generated by intercrossing F1 mice. Mice were fed chow diet containing 4% fat (Ralston-Purina Co., St. Louis, MO) until 8 weeks of age and then were placed on a high-fat "Western" diet containing 42% fat and 0.15% cholesterol (Teklad 88137, Harlan Teklad, Madison WI) for 12 weeks. At 20 weeks mice were sacrificed, after a 12-hour fast adipose tissues were dissected and flash frozen in LN2 and stored at -80Â°C.
