This invention relates to compounds, compositions, and methods useful for
modulating matrix metalloproteinase (e.g., MMP13) gene expression using
short interfering nucleic acid (siNA) molecules. This invention also
relates to compounds, compositions, and methods useful for modulating the
expression and activity of other genes involved in pathways of MMP13 gene
expression and/or activity by RNA interference (RNAi) using small nucleic
acid molecules. In particular, the instant invention features small
nucleic acid molecules, such as short interfering nucleic acid (siNA),
short interfering RNA (siRNA), double-stranded RNA (dsRNA), micro-RNA
(miRNA), and short hairpin RNA (shRNA) molecules and methods used to
modulate the expression of MMP13 genes.
