Abstract: The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of an Aha gene (Aha1 gene), comprising an antisense strand having a nucleotide sequence which is less that 30 nucleotides in length, generally 19-25 nucleotides in length, and which is substantially complementary to at least a part of an Aha gene. The invention also relates to a pharmaceutical composition comprising the dsRNA together with a pharmaceutically acceptable carrier, methods for treating diseases caused by Aha1 expression and the expression of an Aha gene using the pharmaceutical composition; and methods for inhibiting the expression of an Aha gene in a cell.

Abstract: The present invention concerns methods of treatment using transforming growth factor beta (TGF-beta) modulators. More specifically, the invention concerns methods of treating disorders associated with undesirable TGF-beta signaling, by administering short interfering RNA which down-regulate the expression of TGF-beta, and agents useful therein.
