    Summary

    Fusion sarcoma (FUS) is an RNA-binding protein genetically and pathologically associated with the rare forms of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD)


    main

    Amyotrophic lateral sclerosis (ALS) is a fatal neurological disease characterized primarily by degeneration of the spinal cord cortex, spinal bulb, and spinal motor neurons (MNs), resulting in paralysis and death


    Mutations in FUS are associated with the most aggressive, early-onset forms of ALS5,6 and the rarer FTD7,8


    To establish a faithful ALS-FUS model to explore disease mechanisms, identify therapeutic targets, and test therapeutic candidates, we generated a series of FUS knock-in mouse lines in which als mutagenesis directly targets internal Derived mouse FUS locus


    Finally, we found that an experimental ASO targeting the FUS transcript (ION363) efficiently silenced wild-type and mutant FUS in the brain and spinal cord of P517L and Δ14 heterozygous mice
