RNA interference as potential therapy for neurodegenerative disease: applications to inclusion-body myositis?

Abstract

The discovery of RNA interference (RNAi) has led to powerful new approaches to silence targeted genes in a sequence-specific manner. The potential therapeutic application of RNAi to neurologic disease is highlighted by the recent success of several laboratories in suppressing the expression of neurodegenerative disease genes in transgenic mouse models. Here I discuss potential applications of RNAi to inclusion-body myositis (IBM) after first reviewing its application more generally to neurologic disease. The clearest application of RNAi to IBM is as a research tool to identify critical target genes that contribute to pathogenesis. Provided that proximal pathogenic targets are identified, RNAi could surface as a potential therapeutic strategy to modulate their expression.
