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:Facioscapulohumeral dystrophy (FSHD; MIM158900, MIM158901) is caused by misexpression of the DUX4 transcription factor in skeletal muscle. Animal models of FSHD are hindered by incomplete knowledge regarding the conservation of the DUX4 transcriptional program in other species. Despite the divergence of their binding motifs, both mouse DUX and human DUX4 in mouse and human muscle cells, respectively, activate genes associated with cleavage-stage embryos, including MERVL and ERVL-MaLR retrotransposons. We found that human DUX4 expressed in mouse cells maintained modest activation of cleavage-stage genes driven by conventional promoters but did not activate MERVL-promoted genes. Thus, the ancestral DUX4-regulated genes are characteristic of cleavage-stage embryos and are driven by conventional promoters, whereas divergence of the DUX4 and 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 establish a basis for animal models recreating the FSHD transcriptome.
