Abstract

Oligonucleotides are provided herein that inhibit XDH expression. Also provided are compositions including the same and uses thereof, particularly uses relating to treating diseases, disorders and/or conditions associated with aberrant XDH expression.

Claims (5)

1 . An siRNA comprising a first RNA oligonucleotide and a second RNA oligonucleotide, wherein the first RNA oligonucleotide consists of the sequence set forth in SEQ ID: 23, and the second RNA oligonucleotide consists of the sequence set forth in SEQ ID: 24.

2 . A pharmaceutical composition comprising the siRNA according to claim 1 and a pharmaceutically acceptable carrier, delivery agent or excipient.

3 . A method of treating gout in a subject in need thereof, the method comprising administering to the subject the siRNA of claim 1 .

4 . A method for reducing xanthine dehydrogenase (XDH) expression in a subject in need thereof, the method comprising administering to the subject the siRNA of claim 1 .

5 . A method for reducing XDH expression in a cell, the method comprising contacting the cell with the siRNA of claim 1 .
