Abstract
Provided herein are double-stranded nucleic acid inhibitor molecules having a sense strand with a stem loop structure and an antisense strand, where the loop portion of the stem loop structure is a triloop. Also provided are methods and compositions for reducing target gene expression and methods and compositions for treating a disease of interest.
Claims29
A double-stranded nucleic acid inhibitor molecule, comprising:
- a sense strand comprising 20-65 nucleotides and having a first region (R1) and a second region (R2);
- an antisense strand comprising 15-40 nucleotides, wherein the sense strand and antisense strand are separate strands;
- and
- a first duplex (D1) formed by the first region of the sense strand and the antisense strand, wherein the first duplex has a length of 15-40 base pairs;
- wherein the second region of the sense strand comprises a first subregion (S1), a second subregion (S2) and a triloop (triL) that joins the first and second regions, wherein the first and second regions form a second duplex (D2).
