Impairment of nuclear factor-kappaB activation increased glutamate excitotoxicity in a motoneuron-neuroblastoma hybrid cell line expressing mutant (G93A) Cu/Zn-superoxide dismutase.

Abstract excerpt

Mutations in the superoxide dismutase 1 (SOD1) gene are linked to glutamate excitotoxicity in familial amyotrophic lateral sclerosis (fALS), but the underlying mechanism remains unclear. We investigated whether nuclear factor-kappaB (NF-kappaB) activation is involved in glutamate excitotoxicity by using motor neuron-neuroblastoma hybrid cells that expressed a mutant (G93A) SOD1 (mtSOD1) or wild-type SOD1...
