Genetic basis of thermal nociceptive sensitivity and brain weight in a BALB/c reduced complexity cross: BALB/cJ vs BALB/cByJ Spinal Cord RNAseq

ABSTRACT: We found BALB/cByJ mice showed enhanced sensitivity on the 53.5°C hot plate and mechanical stimulation in the von Frey test compared to BALB/cJ mice and replicated decreased gross brain weight in BALB/cByJ versus BALB/cJ. We then identified a quantitative trait locus (QTL) on chromosome 13 for hot plate sensitivity (LOD = 10.7; p < 0.001; peak = 56 Mb) and a QTL for brain weight on chromosome 5 (LOD = 8.7; p < 0.001). Expression QTL mapping of brain tissues identified H2afy (56.07 Mb) as the top transcript with the strongest association at the hot plate locus (FDR = 0.0002) and spliceome analysis identified differential exon usage within H2afy associated with the same locus. These data are spinal cord RNAseq to confirm differential expression of H2afy and other candidate genes.

RNA Expression QTL mapping in an F2 cross of BALB/cJ and BALB/cByJ mice to identify candidate genes for behavioral/metabolic QTLs

Project description:We found BALB/cByJ and BALB/cJ mice differ in their responses to oxycodone state dependent conditioned place preference, whole brain [oxycodone] and its metabolites [noroxycodone] and [oxymorphone] following oxycodone administration, the 53.5°C hot plate, mechanical stimulation in the von Frey test, and gross brain weight. We then identified a quantitative trait locus (QTL) on chromosome 15 for whole brain (LOD = 7.07; p < 0.001), 13 for hot plate sensitivity (LOD = 10.7; p < 0.001; peak = 56 Mb) and a QTL for brain weight on chromosome 5 (LOD = 8.7; p < 0.001). These tissues were used for expression QTL mapping to highlight the candidate genes Zhx2 (57 Mb) as the top transcript with the strongest association at the ch15 oxymorphone locus and identified H2afy (56 Mb) as the top transcript with the strongest association at the ch13 hot plate locus.

RNA Expression in the left lateral lobe of the liver in BALB/cJ and BALB/cByJ substrains of mice to identify candidate mechanisms for Oxycodone QTLs

Project description:We found BALB/cByJ and BALB/cJ mice differ in their responses to oxycodone state dependent conditioned place preference, whole brain [oxycodone] and its metabolites [noroxycodone] and [oxymorphone] following oxycodone administration, the 53.5°C hot plate, mechanical stimulation in the von Frey test, and gross brain weight. We then identified a quantitative trait locus (QTL) on chromosome 15 for whole brain [Oxymorphone] (LOD = 7.07; p < 0.001), 13 for hot plate sensitivity (LOD = 10.7; p < 0.001; peak = 56 Mb) and a QTL for brain weight on chromosome 5 (LOD = 8.7; p < 0.001). These tissues were used to investigate the transcriptome of the liver in parental strain mice in order to generate hypothosis concerning the quantitative trait mechanism for our observed effects.

A natural loss-of-function deletion of the cytohesin 1 (Cyth1) gene in BALB/cByJ mice does not impact cardiomyocyte polyploidy

Project description:Mammalian cardiomyocytes (CMs) mostly become polyploid shortly after birth. Because this feature may relate to several aspects of heart biology, including regeneration after injury, the mechanisms that cause polyploidy are of interest. BALB/cJ and BALB/cByJ mice are highly related sister strains that diverge substantially in CM ploidy. We identified a large deletion in the Cyth1 gene that arose uniquely in BALB/cByJ mice that creates a null allele. The deletion also results in ectopic transcription of the downstream gene Dnah17, although this transcript is unlikely to encode a protein. By evaluating the natural null allele from BALB/cByJ and an engineered knockout allele in the C57BL/6 background, we determined that absence of Cyth1 does not by itself influence CM ploidy. The ready availability of BALB/cByJ mice may be helpful to other investigations of Cyth1 in other biological processes.

H3K9-butyryl (H3K9Bu) and H3K9-acetyi (H3K9ac) genome patterns before and after transverse aortic constriction in Balb/cJ and Balc/cByJ mice

Project description:Balb/cJ mice on a low-fat diet show a decline in promoter H3K9-butyryl (H3K9Bu) in the heart, after subjecting them to transverse aortic constriction (TAC). In contrast, Balb/cByJ, which has a deletion in the ACADS gene, exhibit an increase in promoter H3K9Bu. Conversely, H3K9ac increases in the former and declines in the latter.

QTL for renal and cardiac function during Angiotensin II and high-sodium treatment of a backcross between C57BL/6J-to-Balb/CJ-F1 and Balb/CJ

Project description:Balb/CJ mice develop heart failure and quickly decompensate during combination treatment with Angiotensin II and high-sodium diet, while C57BL/6J mice do not. Balb/CJ show a predominantly diastolic heart failure, signs of increased pulmonary pressure, relative sodium and fluid retention, peripheral edema and decompensate with anuria in a cardiorenal syndrome. A F1 cross between the strains have a similar phenotype as C57BL/6J, i.e. is protected. The present study used a second generation backcross of the F1-generation to Balb/CJ and pheotyped a wide variety of renal and circulatory and cardiac traits, identifying 9 new QTL.

Transcription profiling of BALB/c mice genetically susceptible to proteoglycan-induced arthritis and spondylitis

Project description:BALB/c mice are susceptible to proteoglycan (PG) aggrecan-induced arthritis (PGIA), a murine model of rheumatoid arthritis (Glant,T.T. and Mikecz,K., Proteoglycan aggrecan-induced arthritis. A murine autoimmune model of rheumatoid arthritis. Methods Mol.Med. 2004. 102: 313-338.). However, there are marked differences among BALB/c colonies (maintained by different vendors at different locations) in PGIA onset and severity, which could be the result of subtle variations in their genetic background. In the present microarray study, we have identified differences among BALB/c colonies, and an altered immunization-related gene expression pattern in PGIA model. Experiment Overall Design: In this study we compared the gene expression profile of 12 spleens from PG-immunized (RNA was isolated 12 days after immunization) and naive mice from BALB/cJ and BALB/cByJ colonies (3-3 from each group), then made comparisons between colonies and based on immunization.
