**Molecular Mechanism and Rationale**
The pathological accumulation of stress granules in neurodegenerative diseases represents a fundamental breakdown in cellular quality control mechanisms, with recent evidence pointing to a sophisticated "ubiquitin code rewiring" phenomenon that renders these aggregates effectively invisible to autophagy machinery. Under normal physiological conditions, stress granules form as adaptive, membraneless organelles through liquid-liquid phase separation driven pr
## **Molecular Mechanism and Rationale**
The hexanucleotide repeat expansion (GGGGCC) in the C9orf72 gene represents the most prevalent genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), accounting for approximately 40% of familial ALS cases and 25% of familial FTD cases. This expansion undergoes repeat-associated non-ATG (RAN) translation, generating five distinct dipeptide repeat proteins (DPRs): poly-glycine-proline (poly-GP), poly-glycine-arginine (poly-
