  • Correction of alpha-1-antitrypsin genetic defects using spliceosome mediated RNA trans splicing
    Publication number: 20060234247
    Abstract: The present invention provides methods and compositions for generating novel nucleic acid molecules through targeted spliceosomal mediated RNA trans-splicing. The compositions of the invention include pre-trans-splicing molecules (PTMs) designed to interact with a SERPINA1 target precursor messenger RNA molecule (target pre-mRNA) and mediate a trans-splicing reaction resulting in the generation of a novel chimeric RNA molecule (chimeric RNA). In particular, the PTMs of the present invention include those genetically engineered to interact with SERPINA1 target pre-mRNA so as to result in correction of SERPINA1 genetic defects responsible for AAT deficiency. The PTMs of the invention may also comprise sequences that are processed out of the PTM to yield duplex siRNA molecules directed specifically to mutant SERPIN A1 mRNAs. Such duplexed siRNAs are designed to reduce the accumulation of toxic AAT protein in liver cells.
