Abstract
The invention relates to the use of short interfering nucleic acid molecules (siNAs, such as siRNAs) that modulate the expression of VEGF-C and/or RhoA involved in neovascular angiogenesis. In the present invention, inhibition of VEGF-C and/or RhoA gene expression lead to decreased expression of VEGF-A, which is required for initiation and the sustaining of angiogenesis. Further, the invention also relates to the inhibition of RhoA expression levels along with VEGF-C, so as to derive the benefits of down-regulating two different targets required for angiogenesis. The present invention describes compounds, compositions and methods useful for inhibition of neoangiogenesis. In certain embodiments, the invention relates to methods for inhibiting neovascularization, as well as compounds, such as VEGF-C and RhoA siRNAs, useful in the treatment of ocular disorders such as age related maculardegeneration (AMD), diabetic retinopathy, glaucoma and other neovascular disorders.
