ALS-linked FUS mutations (P525L, R521C, R514S) alter phase separation properties, leading to stress granules with increased internal viscosity and delayed dynamics. Liquid-liquid phase separation dynamics critically determine whether stress granules can be recognized and engulfed by autophagosomes - more solidified granules may exceed size or compliance thresholds for autophagosomal capture despite adequate ubiquitination signals. This mechanism addresses how material properties influence cleara
# ASO-Mediated Exon Skipping to Restore FUS-TAZ Chaperone Axis
## Background and Rationale
Fused in Sarcoma (FUS) is a multifunctional DNA/RNA-binding protein belonging to the FET family that plays critical roles in transcription regulation, RNA processing, and genomic maintenance. Pathogenic variants in FUS account for approximately 5% of familial amyotrophic lateral sclerosis (ALS) cases and are increasingly recognized in frontotemporal dementia (FTD), particularly in cases with juvenile ons
