Figure 4From: 1,2-Dioleoyl-3-Trimethylammonium-Propane (DOTAP)-Formulated, Immune-Stimulatory Vascular Endothelial Growth Factor A Small Interfering RNA (siRNA) Increases Antitumoral Efficacy in Murine Orthotopic Hepatocellular Carcinoma with Liver Fibrosis(A, a, and B) Representative images from mice treated either with fluoresceinlabeled naked siRNA without DOTAP formulation (A and a) or with DOTAP fluoresceinlabeled siRNA (B). Original magnification 100× (A/B), 200× (a). (C) Effect of DOTAP-formulated naked VEGF-A siRNA on hepatic VEGF expression. Gene silencing was significantly increased by the use of DOTAP VEGF-A siRNA compared with naked VEGF-A siRNA (P = 0.0014).Back to article page
