Project description:CGH comparing 3 inbred mouse strains to a C57BL/6 reference. The 3 inbred strains used have known trypanotolerance phenotypes, and these data were originally acquired as part of a study investigating the genetic mechanisms underlying trypanotolerance. These data have also been used in conjunction with the Perlegen 8 million SNP dataset to examine the effect of sequence mismatches on the log2 signal ratios acquired by these long oligonucleotide arrays. Keywords: comparative genomic hybridisation

Project description:Gene-profiling of Tregs across inbred strains. There is a wide inter-individual range in the frequency of FoxP3+ Treg cells, but little is known about the underlying genetic or epigenetic mechanisms. We explored this issue accross inbred strains of mice. During this study, we established the gene expression profiles of Treg cells from the various inbred strains of mice.

Project description:Genetic variation in the population has an influence on the manifestation of monogenic as well as multifactorial disorders, with the underlying genetic contribution dependent on several interacting variants. Common laboratory mouse strains used for modelling human disease lack the genetic variability of the human population. Therefore, outcomes of rodent studies show limited correlation with human disease. The functionality of brain vasculature is an important modifier of brain diseases. Importantly, the restrictive interface between blood and brain – the blood-brain barrier (BBB) serves as a major obstacle for CNS drug delivery. Using genetically diverse mouse strains, we aimed to investigate the phenotypic and transcriptomic variation of the intact BBB in different inbred mouse strains.We investigated the heterogeneity of brain vasculature in recently wild-derived mouse strains (CAST/EiJ, WSB/EiJ, PWK/PhJ) and long-inbred mouse strains (129S1/SvImJ, A/J, C57BL/6J, DBA/2J, NOD/ShiLtJ) using different phenotypic arms. We used immunohistochemistry and confocal laser microscopy followed by quantitative image analysis to determine vascular density and pericyte coverage in two brain regions – cortex and hippocampus. Using a low molecular weight fluorescence tracer, sodium fluorescein and spectrophotometry analysis, we assessed BBB permeability in young and aged mice of selected strains. For further phenotypic characterization of endothelial cells in inbred mouse strains, we performed bulk RNA sequencing of sorted endothelial cells isolated from cortex and hippocampus. We did not detect differences in cortical and hippocampal vessel density and pericyte coverage among all the investigated strains. The staining patterns of endothelial arteriovenous zonation markers were similar in different strains. BBB permeability to a small fluorescent tracer, sodium fluorescein, was also similar in different strains. Transcriptomic analysis of endothelial cells revealed that sex of the animal was a major determinant of gene expression differences. In addition, the expression level of several genes implicated in endothelial function and BBB biology differed between wild-derived and long-inbred mouse strains. Our analysis shows that although there were no major differences in parenchymal vascular morphology and BBB permeability between investigated mouse strains or sexes, transcriptomic differences of brain endothelial cells point to variation in gene expression of the intact BBB. These baseline variances might be confounding factors in pathological conditions that may lead to a differential functional outcome dependent on the sex or genetic polymorphism.

Project description:Study to map diabetes-related traits in the Diversity Outbred (DO) mouse cohort. The DO is an outbred mouse population derived from 8 inbred mouse strains, including 3 wild-derived strains. The DO captures a broad range of genetic variation comparable to that found in human populations (SVENSON et al. 2012), and presents a similarly broad range of individual susceptibility to T2D. We metabolically challenged 500 DO mice with a high-fat/high-sucrose diet, measured a host of diabetes-related physiological phenotypes (e.g., plasma glucose and insulin), and isolated their pancreatic islets for functional and molecular characterization. We performed RNA-seq to determine the genetic architecture of gene expression in islets

Project description:Submicroscopic (< 2 Mb) segmental DNA copy number changes are a recently recognized source of genetic variability between individuals. The biological consequences of copy number variants (CNVs) are largely undefined. CNVs have been detected in diverse species, including mice and humans. Published studies in mice have been limited by resolution and strain selection. We chose to study twenty-one well-characterized inbred mouse strains that are the focus of an international effort to measure, catalog, and disseminate phenotype data. We performed comparative genomic hybridization using long oligomer arrays (oligo-aCGH) to characterize CNVs in these strains. This technique increased the resolution of CNV detection by more than an order of magnitude over previous methodologies. The CNVs range in size from 21-2,002 kb. Clustering strains by CNV profile recapitulates aspects of the known ancestry of these strains. Most of the CNVs (77.5%) contain annotated genes. We demonstrate that this technique can identify copy number differences associated with known polymorphic traits. The phenotype of previously uncharacterized strains can be predicted based on their copy number at these loci. Annotation of CNVs in the mouse genome combined with sequence-based analysis provides an important resource that will help define the genetic basis of complex traits.

There is a wide inter-individual range in the frequency of FoxP3+ Treg cells, but little is known about the underlying genetic or epigenetic mechanisms. We explored this issue accross inbred strains of mice. During this study, we established the gene expression profiles of Treg cells from the various inbred strains of mice. For each inbred strain of mice, CD4+ TCRb+ CD25hi Treg cells (50k) from 9w old male (Jackson laboratory) were double sorted into Trizol. For BM Treg, cells were triple-sorted. Top 50% among CD25high cells were selected to ensure high Foxp3+ purity (over 99%). 2 biological replicates per condition. RNA was amplified, labeled and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays (Expression Analysis).
