ANDROGEN RECEPTOR NUCLEIC ACIDS AND USES THEREOF
Disclosed herein are molecules and pharmaceutical compositions that mediate RNA interference against androgen receptor. Also described herein include methods for treating a disease or disorder that comprises a molecule or a pharmaceutical composition that mediate RNA interference against androgen receptor.
1 . A small interfering RNA (siRNA) consisting of:
a) the sense strand: 5′-guGfuCfaCfuAfuGfgAfgCfuCfuCfdTsdT-3′ (SEQ ID NO:277), and
b) the antisense strand: 5′-GfAfgAfgCfuCfcAfuAfgUfgAfcAfcdTsdT-3′ (SEQ ID NO:278);
wherein a, u, g, or c, is a 2′-O-methyl modified nucleotide; Af, Uf, Gf, or Cf, is a 2′-fluoro modified nucleotide; dT is the deoxythymidine residue; and s is a phosphorothioate backbone modification, and wherein the siRNA induces greater than 68% reduction in androgen receptor mRNA levels.
2 . A pharmaceutical composition comprising:
a) the siRNA of claim 1 ; and
b) a pharmaceutically acceptable excipient.
3 . The pharmaceutical composition of claim 2 , wherein the pharmaceutical composition is formulated as a nanoparticle formulation.
4 . The pharmaceutical composition of claim 2 , wherein the pharmaceutical composition is formulated for parenteral, oral, intranasal, buccal, rectal, or transdermal administration.
5 . A method of treating cancer in a patient in need thereof, comprising administering to said patient a composition comprising the siRNA of claim 1 .
6 . The method of claim 5 , wherein the cancer comprises an androgen receptor-associated cancer.
