iRNA agents targeted to the Rho-A gene
View Patent ↗The invention relates to compositions and methods for modulating the expression of the RhoA gene, and more particularly to the downregulation of RhoA by chemically modified oligonucleotides.
1. An iRNA agent comprising a sense strand and an antisense strand, wherein each strand is 21 nucleotides in length, and wherein the sequence of the sense strand is identical to the sense strand sequence of agent number 6662 (SEQ ID NO:557), and wherein the sequence of the antisense strand is identical to the antisense strand sequence of agent number 6662 (SEQ ID NO:558), and wherein every pyrimidine in the sense strand except for deoxythimidine is 2′-O-methyl modified, and wherein every 5′-nucleotide in 5′-ua-3′ motifs in the antisense strand is 2′-O-methyl modified, and wherein the 21 nucleotides include two deoxythymidine nucleotides at the 3′ end of each strand.
2. The iRNA agent of claim 1 , wherein said deoxythymidine nucleotides at the 3′ end of each strand comprise a phosphorothioate linkage.
3. The iRNA agent of claim 2 , further comprising a cholesterol moiety conjugated to the deoxythymidine nucleotide at the 3′-end of the sense strand of the iRNA agent.
4. A composition, comprising:
a.) an iRNA agent of claim 1 , 2 or 3 ; and
b.) a pharmaceutically acceptable carrier.
5. An isolated cell comprising an iRNA agent of claim 1 , 2 or 3 .
