The direction of cross affects obesity after puberty in male but not female offspring

ABSTRACT: We investigated parent-of-origin and allele-specific expression effects on obesity and hepatic gene expression in reciprocal crosses between the Berlin Fat Mouse Inbred line (BFMI) and C57Bl/6NCrl (B6N). We sequenced mRNA extracted from liver tissue of 10 M. Musculus individuals. 4 liver samples were collected from 10 week old inbred strains (1 male and 1 female Berlin Fat Mouse Inbred line (BFMI), 1 male and 1 female C57Bl/6NCrl (B6N)) and 6 liver samples collected from 10 week old F1 males using a reciprocal cross design (3 paternal BFMI (patBFMI) vs 3 maternal BFMI (matBFMI)).

The direction of cross affects obesity after puberty in male but not female offspring

Project description:We investigated parent-of-origin and allele-specific expression effects on obesity and hepatic gene expression in reciprocal crosses between the Berlin Fat Mouse Inbred line (BFMI) and C57Bl/6NCrl (B6N). We sequenced mRNA extracted from liver tissue of 10 M. Musculus individuals. 4 liver samples were collected from 10 week old inbred strains (1 male and 1 female Berlin Fat Mouse Inbred line (BFMI), 1 male and 1 female C57Bl/6NCrl (B6N)) and 6 liver samples collected from 10 week old F1 males using a reciprocal cross design (3 paternal BFMI (patBFMI) vs 3 maternal BFMI (matBFMI)). Reciprocal crosses were generated from the Berlin Fat Mouse Inbred line BFMI860-12/Hber (BFMI) and C57BL/6NCrl (B6N). Seven BFMI males were mated with seven B6N females and six B6N males with six BFMI860 females to generate 48 F1 animals (deemed patBFMI and matBFMI, respectively). Each reciprocal F1 offspring groups consisted of 12 males and 12 females. From these animals three F1 males from three BFMI females and three F1 males from three B6N females were used for RNA-seq measurements. One high fat diet raised male and female from each inbred parental strain (BFMI and B6N) were used as parental strain control animals and measured via RNA-seq as well.

Microarray gene expression data in liver, gonadal adipose tissue, pancreatic islets, and skeletal muscle in two lines of the Berlin Fat Mouse (BFMI861-S1 and BFMI861-S2)

Project description:The Berlin Fat Mouse Inbred line (BFMI) is a model for obesity and the metabolic syndrome. This study aimed to identify genetic variants associated with liver weight, liver triglycerides, and body weight using the obese BFMI sub-line BFMI861-S1. BFMI861-S1 mice are insulin resistant and store ectopic fat in the liver.

Gene expression profiles of young and aged endothelial cells isolated from the murine liver

Project description:To investigate the effect of aging on liver endothelial cells, we performed RNA sequencing of liver endothelial cells isolated from young (10-week-old) and aged (127-136 week-old) C57BL/6J mice.

Effects of linoleic acid metabolite on liver gene expression in a diet-induced NAFLD/NASH model.

Project description:To investigate the alterlation of liver gene expression by linoleic acid (LA) metabolite HYA (10-hydroxy-cis-12-octadecenoic acid) in a diet-induced NAFLD/NASH model, we evaluated liver of male C57BL/6J mice fed a nomal diet (ND), a high fat diet (HFD, Control(CT)), HFD supplemented with 1% HYA (HYA), or HFD supplemented with 1% LA (LA) for 26 weeks from 5-week-old. We then performed gene expression profiling analysis using data obtained from RNA-seq of these 4 groups.

Transcriptome profiles of female and male mouse liver

Project description:Sexual dimorphism of gene expression is commonly observed in mammalian tissues, including liver. To assess sexual dimorphisms in gene expression, we profiled the transcriptome of liver tissue from 20-week old male and female mice of the C57BL/6N (B6) and C3H/HeN (C3) inbred mouse strains using RNA-seq. These two inbred mouse strains exhibit phenotypic differences in liver biology, as they are at opposite ends of the spectrum of spontaneous hepatocellular carcinoma incidence; C3 mice are highly susceptible to develop spontaneous liver tumors as a function of age, while B6 mice are extremely resistant. Overall, these datasets provide insight into the underlying gene expression patterns that should be considered when assessing sex differences in mouse liver.

Compensatory cis-trans regulation of mouse liver gene expression

Project description:Two inbred mouse strains, C57BL/6J and CAST/EiJ, were crossed to generate both initial and reciprocal F1 crosses. For each genetically distinct class of mice (F0 C57BL/6J, F0 CAST/EiJ, F1i - C57BL/6J x CAST/EiJ, F1r - CAST/EiJ x C57BL/6J, where the male parent is listed first), samples were collected from a single lobe of the liver from 6 male mice between the ages of 4 and 6 months. The 24 samples were then processed to generate strand-specific RNA-seq libraries, which were sequenced on the Illumina GAII platform using 72bp paired-end reads.

C57BL/6 substrain differences in inflammatory and neuropathic nociception and genetic mapping of a major quantitative trait locus underlying acute thermal nociception

Project description:Sensitivity to different pain modalities has a genetic basis that remains largely unknown. The use of closely related inbred mouse strains can facilitate gene mapping of nociceptive behaviors in preclinical pain models. We previously reported enhanced sensitivity to acute thermal nociception in C57BL/6J (B6J) versus C57BL/6N (B6N) substrains. Here, we expanded on pain phenotypes and observed an increase in inflammatory nociceptive behaviors induced by hindpaw formalin injections in B6J versus B6N mice (Charles River Laboratories). No strain differences were observed in mechanical or thermal hypersensitivity or in paw diameter following the Complete Freund s Adjuvant (CFA) model of inflammatory pain, indicating specificity in the inflammatory nociceptive stimulus. In the chronic nerve constriction injury (CCI), a model of neuropathic pain, no strain differences were observed in baseline mechanical threshold or in mechanical hypersensitivity up to one month post-CCI. We replicated the enhanced thermal nociception in B6J mice in the 52.5 C hot plate test relative to B6N mice from The Jackson Laboratory. Using a B6J x B6N-F2 cross (N=164), we mapped a major QTL underlying hot plate sensitivity to chromosome 7 that peaked at 26 Mb (LOD = 3.81, 8.74 Mb-36.50 Mb) that was more pronounced in males. Genes containing expression QTLs (eQTLs) associated with the peak nociceptive marker that have been implicated in pain and inflammation include Ryr1, Cyp2a5, Pou2f2, Clip3, Sirt2, Actn4, and Ltbp4 (FDR < 0.05). Future studies involving positional cloning and gene editing will determine the quantitative trait gene(s) and potential pleiotropy of this locus across other pain modalities. RNA-seq data and genotype information from striatum punches of F2 C57BL/6J (B6J) cross C57BL/NJ (B6NJ) oxycodone-treated mice. Genotypes are given relative to B6J allele, eg 0 = homozygous B6J.

Gene expression in diet-induced obesity resistent (DIO non-responder) and diet-induced obesity susceptible (DIO responder) C57BL/6J mouse strain

Project description:Inbred C57BL/6J mice differ in their susceptibility to diet-induced obesity. Comparison of the liver transcriptomes leads to genes that are involved in the development as well as the maintenance of fatty liver during the onset of obesity upon high fat diet feeding. Genes being upregulated in DIO responder can be seen as drivers of fatty liver development, while genes upregulated in DIO non-responder are most likely involved in the protection against fatty liver diseases.

Constraint and divergence of global gene expression in the mammalian embryo

Project description:We profiled genome-wide gene expression of 170 individual mid-gestation (embryonic day 11.5) whole mouse embryos derived from a 2-generation interspecies mouse cross and asked to what extent genetic variation drives four important parameters of regulatory architecture: allele-specific expression (ASE), imprinting, trans-regulatory effects, and maternal effect. The inbred strain C57BL/6J and wild-derived inbred strain CAST/EiJ were used in reciprocal crosses to generate F1 embryos. F1 progeny were backcrossed to C57BL/6J in reciprocal crosses to generate 154 N2 embryos. We employed a backcross design, in which N2 offspring have genotypically distinct parents, to enable comparison of gene expression for offspring from each side of the reciprocal cross. Our findings demonstrate that genetic variation contributes to widespread gene expression differences during mammalian embryogenesis. Transcriptome analysis of E11.5 mouse embryos: 16 F1 embryos from reciprocally crossed C57BL/6J and CastEi/J parents; and 154 N2 embryos from reciprocal backcross of F1s to the C57BL/6J parent.
