Quantify the effects of TTF1 on the expressions of vascular endothelial growth factor and basic fibroblast growth factor. Different doses of compound were used as treatments in the HepG-2-transplanted nude mice as follows: sTTF1 (5 μmol/kg), TTF1 (10 μmol/kg), lTTF1 (20 μmol/kg), apigenin (40 μmol/kg), and Con (control group treated with normal saline). aP < 0.05, bP < 0.01 vs control group. VEGF: Vascular endothelial growth factor; bFGF: Basic fibroblast growth factor.
