Microinjection of catalase cDNA prevents hydrogen peroxide-induced motoneuron death.

Abstract

Oxidative stress is believed to play a central role in the pathogenesis of amyotrophic lateral sclerosis (ALS). We investigated the protective effects of overexpression of catalase in primary cultures of rat spinal motoneurons against the oxidative stress of hydrogen peroxide. Using microinjection, catalase-encoding cDNA was transferred into the motoneurons… (More)
