Abstract: Disclosed herein are oligomeric compounds such as antisense oligonucleotides, siRNA and shRNAs and compositions for knocking down human RACK1, and methods for treating a TDP43-opathy or a FUS-opathy neurodegenerative disease optionally selected from amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), frontotemporal lobar dementia (FTLD), Huntington's disease (HD), neuronal intermediate filament inclusion disease (NIFID), basophilic inclusion body disease (BIBD) or limbic-predominant age-related TDP-43 encephalopathy (LATE) in a subject in need thereof or for reducing TDP-43 and/or FUS aggregation in a cell, the methods comprising administering to the subject in need thereof or introducing into the cell one or more antisense molecule(s) targeting RACK1, optionally one or more oligomeric compound disclosed herein.
