Expression data from thioglycollate-elicited peritoneal macrophages from 129S6/SvEvTac and C57BL/6 mice

ABSTRACT: Strain differences influence susceptibility to atherosclerosis. Apolipoprotein E-null mice on a C57BL/6 genetic background (B6-apoE) are highly susceptible to atherosclerosis in the aortic root area compared with those on a 129S6/SvEvTac background (129-apoE). To explore strain-specific differences affecting the susceptibility to atherosclerosis, we performed microarray analysis of macrophages from wild type mice of each strains.

Strain-specific differences in brain gene expression in a hydrocephalic mouse model with motile cilia dysfunction

Project description:Analysis of strain-specific differences in gene expression in brains from a hydrocephalic mouse model of primary ciliary dyskinesia. The results identify genes that are differentially expressed between C57BL6/J and 129S6/SvEvTac brains. These genes encode proteins that function in a variety of cellular processes and include some that are relevant to hydrocephalus and cilia function, providing insight into the mechanisms underlying susceptibility to hydrocephalus.

Characterization of cholesterol loading effect on the gene expression of bone marrow derived macrophages of AKR and DBA/2 ApoE-deficient mice

Project description:Strain effects on the response to cholesterol loading in bone marrow derived macrophages (BMM) are not well studied. The atherosclerosis susceptible strain, DBA/2 on the ApoE deficient background and the atherosclerosis resistant AKR strains show differences in cholesterol handling when loaded with AcLDL. To understand the molecular basis for these differences, BMM from both strains were loaded with acetylated low desnisty lipoprotein (AcLDL) and gene expression quantified. BMMs from AKR greatly upregulated transcripts involved in the lysosomal trafficking pathway. This experiment strongly suggest that upregualtion of the lysosomal pathway in response to AcLDL maybe protective against atherosclerosis. In addition we find that transcripts containing the sterol response element (SRE) motif had strong strain-loading interactions suggesting a strain response to SRE response.

RNA-seq analysis of Scn1+/- Dravet mice on susceptible and resistant strains at postnatal days 14 and 24

Project description:Dravet syndrome is a severe, early-onset epileptic encephalopathy frequently resulting from de novo mutations of SCN1A. Mice with heterozygous deletion of Scn1a (Scn1a+/-) model many features of Dravet syndrome, including spontaneous seizures and premature lethality. Scn1a+/- mice exhibit variable phenotype penetrance and expressivity dependent upon the strain background. On the 129S6/SvEvTac (129) strain, Scn1a+/- mice do not display an overt phenotype. However Scn1a+/- mice on the [129S6xB6]F1 strain (F1.Scn1a+/-) exhibit juvenile-onset spontaneous seizures and premature lethality. QTL mapping identified several modifier loci responsible for strain-dependent differences in survival of Scn1a+/- mice, but these loci do not account for all the observed phenotypic variance. Global RNA-seq analysis was performed to identify additional genes and pathways that may contribute to variable phenotypes. Hippocampal gene expression was analyzed in wild-type (WT) and Scn1a+/- mice on both F1 and 129 strains, at two time points during disease development. There were few gene expression differences between 129.WT and 129. Scn1a+/- mice and approximately 100 genes with small expression differences (6-36%) between F1.WT and F1.Scn1a+/- mice. Strain-specific gene expression differences were more pronounced, with dozens of genes with >1.5-fold expression differences between 129 and F1 strains. Age-specific and seizure-related gene expression differences were most prominent, with hundreds of genes with >2-fold differences in expression were identified between groups with and without seizures, suggesting potential differences in developmental trajectory and/or homeostatic plasticity during disease onset. Global expression differences in the context of Scn1a deletion may account for strain-dependent variation in seizure susceptibility and survival observed in Scn1a+/- mice.

Mouse brain region gene expression (430 2.0 Array)

Project description:Gene expression patterns were determined from five brain regions (bed nucleus of the stria terminalis, hippocampus, hypothalamus, periaqueductal gray, and pituitary gland) in six mouse strains (129S6/SvEvTac, A/J, C57BL/6J, C3H/HeJ, DBA/2J, and FVB/NJ). At least two replicate samples per brain region/strain were analyzed using Affymetrix Mouse Genome 430 2.0 arrays. Keywords: mouse strain and brain region comparison

Transcription profiling of mouse offspring of crosses between hypercholesterolemic and normocholesterolemic parents LUMC-HKG-ApoE-Atherosclerosis

Project description:Enhanced prenatal fatty streak formation in human fetuses has been associated with maternal hypercholesterolemia. However, the possible roles of maternal genetic background and in utero environment on development of atherosclerosis in adult life have not been unraveled. We generated genetically identical heterozygous apoE-deficient mice offspring with a different maternal background to study the intrauterine effect of maternal genotype and associated hypercholesterolemia on the developing vascular system. As read out for increased atherosclerosis development in adult life, a constrictive collar was placed around the carotid artery to induce lesion formation. A significant increase in endothelial cell activation and damage was detected in the carotid arteries of heterozygous apoE-deficient fetuses with apoE-deficient mothers compared with offspring from wild type mothers, but no fatty streak formation was observed. Postnatally, all carotid arteries revealed normal morphology. In adult offspring with maternal apoE-deficiency, the constrictive collar resulted in severe lesion (9/10) development compared with no to only minor lesions (2/10) in offspring of wild type mothers. Microarray analysis showed no effect of maternal apoE-deficiency on gene expression in adult offspring. We conclude that maternal apoE-deficiency not only affects fetal arteries, but also increases the susceptibility for development of collar-induced atherosclerosis in adult life. Experiment Overall Design: Crossing of hypercholesterolemic female with normocholesterolemic male and vice versa, determination of susceptabilioty to atherosclerosis in offspring
