1. VEGF-A inhibition impedes proliferation in Amppos tumors.
VEGF-A inhibition impedes proliferation in Amppos tumors. Mdr2−/− mice were treated with adenovectors expressing either GFP alone or GFP and sFLT for 10 days. A, representative photomicrographs of IHC for BrdUrd. Tumor-infiltrating cells remain proliferative. Scale bar, 100 μm. B, BrdUrd immunostaining was quantified using automated image analysis (n ≥ 6; *, P < 0.05). C, mRNA qPCR analysis of the indicated genes in Ampneg and Amppos tumors treated with the indicated adenovectors. Each dot represents a different tumor. The cross line signifies geometric mean (***, P < ). D, left, histologic section stained with H&E depicting necrosis, representing three out of the six sFLT-treated Amppos tumors. Scale bar, 500 μm. Right, a macroscopic picture of a tumor with hemorrhagic necrosis. Scale bar, 0.5 cm.
