Methods and compositions of improved modified siRNA |
摘要 |
Chemically modified small interfering RNAs (siRNAs) that include both phosphorodithioate modifications (PS2-RNA) and 2′-O-methyl modifications (MePS2) provide improved RNA silencing. Specific chemically modified siRNA that show enhanced silencing of RNAs involved in resistance to chemotherapeutic agents are provided. |

1. A chemically modified siRNA directed to interference with a RISC Ago2 slicer associated with chemoresistance in ovarian cancer cell lines and tumors, wherein the chemical modifications to the siRNA comprise a combination of 2′-OMe and PS2 modifications on either or both sense and antisense strands of the siRNA that improve serum stability and gene silencing efficacy. |
