New hope for therapy in neurodegenerative diseases

Abstract

The use of genetic screens to define cellular pathways that regulate neurodegenerative disease proteins has emerged as a powerful strategy to identify potential therapeutic targets for these disorders. Using cross-species genetic screens, Park et al. recently identified RAS-MAPK-MSK1 as a cellular pathway that modulates levels of the polyglutamine-containing protein ATXN1 and its subsequent toxicity in SCA1. © 2013 IBCB, SIBS, CAS.
