Knockdown of glutathione S-transferase leads to mislocalization and accumulation of cabeza, a homolog of FUS, in the brain.

Glutathione S-transferase omega (GSTO) is an antioxidant enzyme involved in reducing oxidative stress. Recent studies suggest that polymorphic variants of GSTOs affect the onset age and progression of neurodegenerative diseases. Although GSTO activity may affect the development and age dependency of several diseases, the mechanism by which GSTO inactivation in neurons regulates the susceptibility to neurodegenerative diseases is unclear.

FUS-induced neurotoxicity is prevented by inhibiting GSK-3β in a Drosophila model of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS)-linked mutations in fused in sarcoma (FUS) lead to the formation of cytoplasmic aggregates in neurons. They are believed to play a critical role in the pathogenesis of FUS-associated ALS. Therefore, the clearance and degradation of cytoplasmic FUS aggregates in neurons may be considered a therapeutic strategy for ALS.
