Familial amyloidotic polyneuropathy (FAP) is a hereditary systemic amyloidosis caused by dominantly acting missense mutations in the gene encoding transthyretin (TTR). The most common mutant TTR is of the Va130Met type, which results from a point mutation. Because the major constituent of amyloid fibrils is mutant TTR, agents that selectively suppress mutant TTR expression could be powerful therapeutic tools. This study has been performed to evaluate the use of small interfering RNAs (siRNAs) for the selective silencing of mutant Va130Met TTR in cell culture systems. We have identified an siRNA that specifically inhibits mutant, but not wild-type, TTR expression even in cells expressing both alleles. Thus, this siRNA-based approach may have potential for the gene therapy of FAR (c) 2005 Elsevier Inc. All rights reserved.
