Project description:Facioscapulohumeral dystrophy (FSHD; OMIM #158900, #158901) is caused by mis-expression of the DUX4 transcription factor in skeletal muscle1. Animal models of FSHD are hampered by incomplete knowledge of the conservation of the DUX4 transcriptional program in other species. Despite divergence of their binding motifs, both mouse Dux and human DUX4 activate genes associated with cleavage-stage embryos, including MERV-L and ERVL-MaLR retrotransposons, in mouse and human muscle cells respectively. When expressed in mouse cells, human DUX4 maintained modest activation of cleavage-stage genes driven by conventional promoters, but did not activate MERV-L-promoted genes. These findings indicate that the ancestral DUX4-factor regulated genes characteristic of cleavage-stage embryos driven by conventional promoters, whereas divergence of the DUX4/Dux homeodomains correlates with retrotransposon specificity. These results provide insight into how species balance conservation of a core transcriptional program with innovation at retrotransposon promoters and provide a basis for animal models that recreate the FSHD transcriptome.

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:Histones were isolated from brown adipose tissue and liver from mice housed at 28, 22, or 8 C. Quantitative top- or middle-down approaches were used to quantitate histone H4 and H3.2 proteoforms. See published article for complimentary RNA-seq and RRBS datasets.
