Repetitive sequences account for more than 50% of the human genome. Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal-dominant disease associated with reduction in the copy number of the D4Z4 repeat mapping to 4q35. By an unknown mechanism, D4Z4 deletion causes an epigenetic switch leading to de-repression of 4q35 genes. Here we show that the… (More)
Facioscapulohumeral muscular dystrophy (FSHD) is a common muscle disease whose molecular pathogenesis remains largely unknown. Over-expression of FSHD region gene 1 (FRG1) in mice, frogs, and worms perturbs muscle development and causes FSHD-like phenotypes. FRG1 has been implicated in splicing, and we asked how splicing might be involved in FSHD by… (More)
Overexpression of facioscapulohumeral muscular dystrophy region gene 1 (FRG1) in mice, frogs and worms leads to muscular and vascular abnormalities. Nevertheless, the mechanism that follows FRG1 overexpression and finally leads to muscular defects is currently unknown. Here, we show that the earliest phenotype displayed by mice overexpressing FRG1 is a… (More)
Several reports showed that hematopoietic stem cells (HSCs) participate in muscle regeneration, raising hope for their therapeutic potential for degenerative muscle diseases. However, proof that HSCs are able to reprogram their fate and enter a myogenic pathway, remains elusive. We demonstrate that murine bone marrow (BM)-derived hematopoietic cells,… (More)
DNA microarrays are powerful tools for the analysis of gene expression on a genomic scale. The importance of individual regulatory events for the process under study can however not be deduced unequivocally without additional experiments. We devised a strategy to identify central regulators of cancer drug responses by combining the results of microarray… (More)
Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant myopathy with a strong epigenetic component. It is associated with deletion of a macrosatellite repeat leading to over-expression of the nearby genes. Among them, we focused on FSHD region gene 1 (FRG1) since its over-expression in mice, Xenopus laevis and Caenorhabditis elegans, leads… (More)
