Project description:Artificial transcription factors (ATFs) and genomic nucleases based on a DNA binding platform consist- ing of multiple zinc finger domains are currently be- ing developed for clinical applications. However, no genome-wide investigations into their binding speci- ficity have been performed. We have created six- finger ATFs to target two different 18 nt regions of the human SOX2 promoter; each ATF is constructed such that it contains or lacks a super KRAB do- main (SKD) that interacts with a complex contain- ing repressive histone methyltransferases. ChIP-seq analysis of the effector-free ATFs in MCF7 breast cancer cells identified thousands of binding sites, mostly in promoter regions; the addition of an SKD domain increased the number of binding sites M-bM-^HM-<5- fold, with a majority of the new sites located out- side of promoters. De novo motif analyses suggest that the lack of binding specificity is due to sub- sets of the finger domains being used for genomic interactions. Although the ATFs display widespread binding, few genes showed expression differences; genes repressed by the ATF-SKD have stronger bind- ing sites and are more enriched for a 12 nt motif. Interestingly, epigenetic analyses indicate that the transcriptional repression caused by the ATF-SKD is not due to changes in active histone modifications. ATF plasmids were designed and stably integrated into MCF7 cells as described in (Stolzenburg et al. 2012). Stable lines were grown at 30M-bM-^@M-^S80% confluency in DulbeccoM-bM-^@M-^Ys Modified EagleM-bM-^@M-^Ys Medium (Corning, Corning, NY) supplemented with 10% heat-inactivated fetal bovine serum (Invitrogen, Life Technologies, Grand Island, NY) and 1% penicillin/streptomycin; cells were selected using 5 M-BM-5g/ml puromycin (VWR, Radnor, PA) and 200 M-BM-5g/ml G418 (VWR, Radnor, PA). ATF expression was induced by treatment with media containing 1M-BM-5g/ml doxycycline (VWR, Radnor, PA) at 0 h, doxycycline media was refreshed at 48 h, and cells were harvested at 72 h. ATF expression was confirmed by hemagglutinin (HA) tag western blot prior to HA ChIP-seq, histone ChIP-seq and RNA-seq analysis. For HA-tag ChIP-seq, stable MCF7 cell lines were induced using 100 ng/ml doxycycline (Sigma) at 0 h, doxycycline media was refreshed at 48 h, and cells were harvested at 72 h by crosslinking in a final concentration of 1% formaldehyde. Crosslinking was stopped after 5 min by adding glycine to a final concentration of 125 mM. Crosslinked cells were washed in cold phosphate buffered saline, lysed using 1 mL low-salt IP buffer (150 mM NaCl, 50 mM Tris-HCl (pH7.5), 5 mM EDTA, NP-40 (0.5%), Triton X-100 (1%) containing protease inhibitors) and aliquoted at 1 M-CM-^W 10M-bM-^HM-'7 cells/mL. Cells are then sonicated to a fragment size range of 500M-bM-^@M-^S800 bp. Samples were then diluted in 1 mL low-salt buffer and incubated with 3 M-BM-5L of anti-HA antibody (Covance, Princeton, NJ). Three-hundred microliter Sepharose A beads (GE Healthcare Life Science) were used for pull-down. Samples were sequenced at the UNC-CH Genome Analysis Facil- ity (Chapel Hill, NC) on an HiSeq (Illumina, San Diego, CA) to read counts of 4.1M-bM-^@M-^S67.3 M total reads. For histone ChIP-seq, antibodies to H3K4me3 (Cell Signaling Tech- nologies CST9751), H3K9Ac (Cell Signaling Technologies CST9649) and H3K9me3 (Diagenode pAb-056-050) were used; samples were prepared as previously described (OM-bM-^@M-^YGeen et al. 2011).

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:Translational research is commonly performed in the C57B6/J mouse strain, chosen for its genetic homogeneity and phenotypic uniformity. Here, we evaluate the suitability of the white-footed deer mouse (Peromyscus leucopus) as a model organism for aging research, offering a comparative analysis against C57B6/J and diversity outbred (DO) Mus musculus strains. Our study includes comparisons of body composition, skeletal muscle function, and cardiovascular parameters, shedding light on potential applications and limitations of P. leucopus in aging studies. Notably, P. leucopus exhibits distinct body composition characteristics, emphasizing reduced muscle force exertion and a unique metabolism, particularly in fat mass. Cardiovascular assessments showed changes in arterial stiffness, challenging conventional assumptions and highlighting the need for a nuanced interpretation of aging-related phenotypes. Our study also highlights inherent challenges associated with maintaining and phenotyping P. leucopus cohorts. Behavioral considerations, including anxiety-induced responses during handling and phenotyping assessment, pose obstacles in acquiring meaningful data. Moreover, the unique anatomy of P. leucopus necessitates careful adaptation of protocols designed for Mus musculus. While showcasing potential benefits, further extensive analyses across broader age ranges and larger cohorts are necessary to establish the reliability of P. leucopus as a robust and translatable model for aging studies.

Project description:BackgroundCopy number variation is an important dimension of genetic diversity and has implications in development and disease. As an important model organism, the mouse is a prime candidate for copy number variant (CNV) characterization, but this has yet to be completed for a large sample size. Here we report CNV analysis of publicly available, high-density microarray data files for 351 mouse tail samples, including 290 mice that had not been characterized for CNVs previously.ResultsWe found 9634 putative autosomal CNVs across the samples affecting 6.87% of the mouse reference genome. We find significant differences in the degree of CNV uniqueness (single sample occurrence) and the nature of CNV-gene overlap between wild-caught mice and classical laboratory strains. CNV-gene overlap was associated with lipid metabolism, pheromone response and olfaction compared to immunity, carbohydrate metabolism and amino-acid metabolism for wild-caught mice and classical laboratory strains, respectively. Using two subspecies of wild-caught Mus musculus, we identified putative CNVs unique to those subspecies and show this diversity is better captured by wild-derived laboratory strains than by the classical laboratory strains. A total of 9 genic copy number variable regions (CNVRs) were selected for experimental confirmation by droplet digital PCR (ddPCR).ConclusionThe analysis we present is a comprehensive, genome-wide analysis of CNVs in Mus musculus, which increases the number of known variants in the species and will accelerate the identification of novel variants in future studies.
