Pathogenic angiogenesis in various diseases including cancer, autoimmune diseases, and age-related macular degeneration is thought to be regressed with anti-angiogenic drugs. TRUE gene silencing is a new technology to eliminate a specific mRNA using synthetic sgRNA and cellular tRNase ZL. To discover anti-angiogenic sgRNAs, we applied TRUE silencing to the VEGF gene. We examined eight sgRNAs for efficacy in targeting exogenous human VEGF mRNA. Many of them worked efficiently in 293 and HeLa cells. Two of them downregulated the endogenous VEGF gene expression in HeLa cells very efficiently, and the efficacy of these two sgRNAs surpassed that of siRNA extremely.
