RNA-seq of Sall2 wild-type, heterozygous and knockout MEFs

ABSTRACT: Genetically engineered mice (GEM) are essential tools for understanding gene function and disease modeling. Due to historical reasons, gene targeting was at first done in embryonic stem cells (ESC) derived from the 129 family of inbred strains, leading to mixed background or congenic mice when crossed with C57BL/6 mice. Depending on the number of backcrosses and breeding strategies genomic segments from 129-derived ESC can be introgressed into the C57BL/6 genome at different levels, establishing a unique genetic makeup that needs characterization in order to obtain valid conclusions of experiments using GEM models. We sequenced wild-type (WT), heterozygous (Het) and knockout (KO) mouse embryonic fibroblasts (MEFs) from a knockout model of Sall2 (Sato A. et al, Zinc finger protein sall2 is not essential for embryonic and kidney development. Mol Cell Biol 2003, 23:62-69) maintained in a mixed background between C57BL/6J and 129P2OlaHsd mice. We also treated these cells with doxorubicin, as a global perturbation of the gene expression. With this schema, we aimed to detect genetic introgression of 129 mice onto C57BL/6J, KO-ligated variants (the so-called congenic footprint) and potential modifier genes.

RNAseq analysis of two independent stains of C57BL/6J-Plat-/- mice and wild-type C57BL/6J.

Project description:The ability to generate defined null mutations in mice revolutionized the analysis of gene function in mammals. However, gene-deficient mice generated by using 129-derived embryonic stem (ES) cells may carry large segments of 129 DNA, even when extensively backcrossed to reference strains, such as C57BL/6J, and this may confound interpretation of experiments performed in these mice. Tissue plasminogen activator (tPA), encoded by the PLAT gene, is a fibrinolytic serine protease that is widely expressed in the brain. A large number of neurological abnormalities have been reported in tPA-deficient mice. The studies here compare genes differentially expressed in the brains of Plat-/- mice from two independent Plat-/- mouse derivations to wild-type C57BL/6J mice. One strain denoted “Old” was constructed in ES cells from a 129 mouse and backcrossed extensively to C57BL/6J, and one denoted “New” Plat-/- mouse was constructed using zinc finger nucleases directly in the C57BL/6J-Plat-/- mouse strain. We identify a significant set of genes that are differentially expressed in the brains of Old Plat-/- mice that preferentially cluster in the vicinity of Plat on chromosome 8, apparently linked to more than 20 Mbp of DNA flanking Plat being of 129 origin. No such clustering is seen in the New Plat-/- mice.

Congenic dissection of a major QTL for methamphetamine sensitivity implicates epistasis

Project description:We identified a congenic mouse with an introgressed region from the A/J donor inbred strain on an inbred C57BL/6J background that showed a reduced locomotor stimulant response to methamphetamine. We conducted microarray analysis of the striatum from drug-naive female and male mice that were 6-9 weeks old. The congenic region is on chromosome 11 and spans approximately 84-96 Mb. There were two groups of mice used in the analysis: B6 control mice versus congenic mice. Congenic mice were collapsed across heterozygous and homozygous genotypes. All mice are on a C57BL/6J background. Congenic mice differ only on chromosome 11 where they contain the introgressed A/J alleles from 84-96 Mb.

Impact of Prnp genetic ablation in the hippocampus transcriptome of congenic B6.129-PrnpZH1/ZH1 or coisogenic C57BL/6-PrnpZH3/ZH3 mice

Project description:To study the effect of Prnp genetic ablation on different aspects of RNA metabolism, we performed RNA sequencing of the hippocampus of wild-type C57BL/6J, congenic B6.129-PrnpZH1/ZH1 and coisogenic C57BL/6J-PrnpZH3/ZH3 mice. We analyzed differential gene expression, exon usage and RNA editing. RNA sequencing on hippocampus of wild-type C57BL/6 mice, congenic B6.129-PrnpZH1/ZH1 and coisogenic C57BL/6-PrnpZH3/ZH3 mice (3 month-old males, n=4 per genotype).

Project description:The potential role of defective cholesterol metabolism in HCC development and exposition the Cyp51 gene as a promising marker with tumor suppressor potential in sex-dimorphic chronic liver pathogenesis in mice. Hepatocyte-specific Cyp51 knock-out (KO) and wild type (WT) mice on a mixed background (129/Pas (10%) × C57BL/6J (90%)) of both sexes (F and M) were investigated at the age of 24 months. From each of KO mice, two samples (a tumor and a surrounding tissue) were considered.

RNA sequencing of C57BL/6J mice, heterozygous for knockout of Hnrnph1 gene, as well as C57BL/6J mice controls

Project description:Previous studies of congenic lines of C57BL/6J-DBA/2J mice compared to C57BL/6 mice revealed a 0.23 QTL for sensitivity to methamphetamine on chromosome 11, which contains two protein coding genes, Rufy1 and Hnrnph1. Subsequent transcription activator-like effector nucleases (TALENs)-mediated introduction of frameshift deletions in the first coding exon of one copy of Hnrnph1 of C57BL/6J mice, revealed comparable association to phenotype. Analysis of the transcriptome and splicesome between these Hnrnph1 heterozygous knockouts and C57BL/6J mice revealed genome-wide differentially expression and exon usage of more than 1000 genes in either.

Mapping of a QTL for airway hyperresponsiveness on mouse chromosome 12

Project description:The BcA86 strain is a unique recombinant congenic strain created from parental strains A/J and C57BL/6J. Naive mice from the BcA86 strain have a lung responsiveness phenotype resembling mice from airway hyperresponsive strain A/J. However, majority of the BcA86 genome is from the hyporesponsive strain C57BL/6J. Our goal was to identify the genomic regions that are associated with this BcA86 phenotype. Using F2 mice generated from BcA86 backcrossed to C57BL/6J, we identified a QTL for airway hyperresponsiveness on mouse chromosome 12. We validated the importance of mouse chromosome 12 in airway responsiveness using a chromosome 12 substitution strain (CSS12) which contains A/J chromosome 12 on a C57BL/6J background. The CSS12 strain also had a lung responsiveness phenotype similar to A/J. We selected genes within our QTL as candidates for airway hyperresponsiveness if they contained a deleterious coding variant (based on PROVEAN analysis) or if they were differently expressed between hyperresponsive (A/J, BcA86, CSS12) and hyporesponsive (C57BL/6J) strains.

Whole-genome gene expression profiling of Pik3cg-depleted mice

Project description:We performed whole-genome gene expression profiling in Pik3cg-/- mice and subsequent gene ontology clustering of differentially expressed genes compared to wild type mice, in order to investigate the role of Pik3cg in platelet membrane biogenesis and blood coagulation. Pik3cg-deficient mice were obtained from sources previously described (T. Sasaki et al, 2000, Science 287, 1040-1046), backcrossed onto the C57BL/6J Jax genetic background for eight generations (B6J;129-Pik3cg-tm1Pngr) and then maintained as a closed colony by intercrossing from within the colony (C57BL/6J Jax contribution: 99.6%).
