Project description:To characterize the genetic basis of hybrid male sterility in detail, we used a systems genetics approach, integrating mapping of gene expression traits with sterility phenotypes and QTL. We measured genome-wide testis expression in 305 male F2s from a cross between wild-derived inbred strains of M. musculus musculus and M. m. domesticus. We identified several thousand cis- and trans-acting QTL contributing to expression variation (eQTL). Many trans eQTL cluster into eleven M-bM-^@M-^Xhotspots,M-bM-^@M-^Y seven of which co-localize with QTL for sterility phenotypes identified in the cross. The number and clustering of trans eQTL - but not cis eQTL - were substantially lower when mapping was restricted to a M-bM-^@M-^XfertileM-bM-^@M-^Y subset of mice, providing evidence that trans eQTL hotspots are related to sterility. Functional annotation of transcripts with eQTL provides insights into the biological processes disrupted by sterility loci and guides prioritization of candidate genes. Using a conditional mapping approach, we identified eQTL dependent on interactions between loci, revealing a complex system of epistasis. Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility. Gene expression was measured in whole testis in males aged 70(M-BM-15) days. Samples include 294 WSB/EiJ x PWD/PhJ F2s, 11 PWD/PhJ x WSB/EiJ F2s, 8 WSB/EiJ, 8 PWD/PhJ, 6 PWD/PhJ x WSB/EiJ F1s and 4 WSB/EiJ x PWD/PhJ F1s.

Project description:To determine if genetic background can modulate severity of an infection, we studied the host responses to influenza infections in the eight genetically highly diverse Collaborative Cross (CC) founder mice. The CC founder (C57BL/6J, 129S1/SvlmJ, CAST/EiJ, PWK/PhJ) were intranasally infected with influenza A/HK/01/68 (H3N2) with 20μl virus solution (1x101 ffu) or mock infected (with PBS). After infection lung was collected at different time points (mock_d3), d3, d5).

Project description:We used a reciprocal cross of Mus musculus and M. domesticus in which F1 males are sterile in one direction and fertile in the other direction, in order to associate expression differences with sterility. Four different crosses were performed. A cross between two strains within each mouse species (M. musculus, PWK/PhJ and CZECHII/EiJ; M. domesticus, LEWES/EiJ and WSB/EiJ). And two reciprocal crosses between a domesticus (LEWES/EiJ) and a musculus (PWK/PhJ) strain. The cross between a musculus female and a domesticus male produces sterile male offspring - whereas all other crosses produced fertile male offspring. Testis tissue from three male mice (60 days old) from all four crosses were analysed on the Affymetrix MG 430.2. Array.

Project description:Nonalcoholic fatty liver disease (NAFLD) is a major health problem and a leading cause of chronic liver disease in the United States and developed countries. In humans, genetic factors greatly influence individual susceptibility to NAFLD. The goals of this study were to compare the magnitude of interindividual differences in the severity of liver injury induced by methyl-donor deficiency among individual inbred strains of mice and to investigate the underlying mechanisms associated with the variability. Feeding mice a choline- and folate-deficient diet for 12 wk caused liver injury similar to NAFLD. The magnitude of liver injury varied among the strains, with the order of sensitivity being A/J ≈ C57BL/6J ≈ C3H/HeJ < 129S1/SvImJ ≈ CAST/EiJ < PWK/PhJ < WSB/EiJ. The interstrain variability in severity of NAFLD liver damage was associated with dysregulation of genes involved in lipid metabolism, primarily with a down-regulation of the peroxisome proliferator receptor α (PPARα)-regulated lipid catabolic pathway genes. Markers of oxidative stress and oxidative stress-induced DNA damage were also elevated in the livers but were not correlated with severity of liver damage. These findings suggest that the PPARα-regulated metabolism network is one of the key mechanisms determining interstrain susceptibility and severity of NAFLD in mice.

Feeding mice a choline- and folate-deficient diet for 12 wk caused liver injury similar to NAFLD. The magnitude of liver injury varied among the strains, with the order of sensitivity being A/J M-bM-^IM-^H C57BL/6J M-bM-^IM-^H C3H/HeJ < 129S1/SvImJ M-bM-^IM-^H CAST/EiJ < PWK/PhJ < WSB/EiJ. The interstrain variability in severity of NAFLD liver damage was associated with dysregulation of genes involved in lipid metabolism, primarily with a down-regulation of the peroxisome proliferator receptor M-NM-1 (PPARM-NM-1)-regulated lipid catabolic pathway genes. Markers of oxidative stress and oxidative stress-induced DNA damage were also elevated in the livers but were not correlated with severity of liver damage. These findings suggest that the PPARM-NM-1-regulated metabolism network is one of the key mechanisms determining interstrain susceptibility and severity of NAFLD in mice. Male A/J, C3H/HeJ and WSB/EiJ inbred mice were maintained on either control or choline- and folate-deficient (CFD) diets for 12 weeks. Gene expression profiles in the livers from control mice and mice fed a CFD-diet were investigated.

Project description:Purpose: To investigate the diet- or strain-dependence of liver transcriptome in eight Diversity Outbred (DO) founder strains [A/J, C57BL/6J (B6), 129S1/SvImJ (129), NOD/ShiLtJ (NOD), NZO/HILtJ (NZO), and three wild-derived strains CAST/EiJ (CAST), PWK/PhJ (PWK), and WSB/EiJ (WSB)] Methods: Total RNA from eight DO founder strains was extracted from snap frozen liver using Maxwell® 16 LEV simplyRNA Tissue Kit (Promega) according to the manufacturer’s protocol. The quality and amount of liver RNA was evaluated using a qubit RNA assay (Invitrogen R11490) and run on an Biorad Bioanalyzer Chip to verify RNA integrity. RNASeq library was prepared by using Illumina TruSeq RNA library construction protocol. RNA samples from 24 mice-fed AIN-93 M diet and 24 mice-fed HFCA diet were submitted to the David H. Murdock Research Institute (DHMRI) for sequencing. The RNA-seq libraries were constructed from 1 µg total RNA after poly-A library preparation. The pooled libraries were sequenced on two lanes of the Illumina HiSeq2500 Instrument. Results: Our liver transcriptomic analysis of eight mouse strains shows that diet and genetic background have a strong effect on the liver transcriptome, which may be related to differences in cardo-metabolic traits. We calculated a gene module consisting of highly correlated transcripts that enriched the biological pathway and provided a searchable database of liver transcript profiles. To further investigate the association of hepatic gene modules with cardio-metabolic traits, Fmo3, a key enzyme in the production of trimethylamine N-oxide (TMAO), and Nox4, which showed strong association with plasma TMAO and liver triglyceride, were identified as the highest expressed in the laboratory-like inbred strains (B6, 129 and NZO) and the lowest expressed transcripts in the CAST strain. We found differences in the production of TMAO and liver triglyceride, which contributes to metabolic syndrome, depending on genetic backgrounds. Conclusions: Our study provide a valuable data resource to the research community and show that liver transcriptomic analysis identified diet- or strain-specific pathways to pathogenesis of metabolic syndrome.

Project description:Collaborative Cross (CC) mouse embryonic fibroblasts (MEF) cells obtained from the eight Founder animals [PWK/PhJ, NZO/HILtJ, NOD/ShiLtJ, WSB/EiJ, A/J, CAST, C57BL/6J, and 129/SvlmJ] were immortalized and the cell lines used to assess differences in transcriptional responses following treatment with mouse recombinant IFNg and IL28. We collected transcriptome profiles for 8 CC MEF cell lines stimulated with either IFNg or IL28 for a total of 16 different biological conditions. Treated and mock samples were collected at 18 hr post-treatment and RNAs extracted and subjected to microarray.
