Figure 2From: 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) Overview of the experimental setting. Fibrosis was induced by the combination of TAA i.p. injections three times per wk and with an additional continuous supplement of EtOH (10% vol/vol) in the drinking water. At wk 24, Hepa129 HCC tumor cells were implanted into fibrotic mice livers and treated with VEGF-A siRNA with different formulations. (B and b) Representative paraffin sections of fibrotic liver samples with intrahepatic HCC satellites 11 d after implantation. Fibrosis was staged according to the score system proposed by Ishak et al. (16). Original magnification 40× (B), 100× (b).Back to article page
