Efficacy of N-acetylcysteine in phenotypic suppression of mouse models of Niemann-Pick disease, type C1.

ABSTRACT: Niemann-Pick disease, type C1 (NPC1), which arises from a mutation in the NPC1 gene, is characterized by abnormal cellular storage and transport of cholesterol and other lipids that leads to hepatic disease and progressive neurological impairment. Oxidative stress has been hypothesized to contribute to the NPC1 disease pathological cascade. To determine whether treatments reducing oxidative stress could alleviate NPC1 disease phenotypes, the in vivo effects of the antioxidant N-acetylcysteine (NAC) on two mouse models for NPC1 disease were studied. NAC was able to partially suppress phenotypes in both antisense-induced (NPC1ASO) and germline (Npc1-/-) knockout genetic mouse models, confirming the presence of an oxidative stress-related mechanism in progression of NPC1 phenotypes and sugges
