Expression of angiogenic factors in pancreatic carcinoma cell and their significance

To investigate the relationship between expression of angiogenic factors and invasion and proliferation in pancreatic carcinoma cell. Expressions and secretions of angiogenic factors in pancreatic carcinoma cell lines were determined by RT-PCR and ELISA. Proliferation and invasion of pancreatic carcinoma cell lines were determined by CCK-8 and Boyden Chamber invasion tests. Pancreatic carcinoma cell lines showed significantly different ability of invasion and proliferation. Intracellular VEGF expressions of SW1990, Capan-1, Aspc-1, MiaPaCa-2, Panc-1 and PCT-3 were (152.9 +/- 0.6), (224.1 +/- 60.3), (239.2 +/- 2.1), (19.3 +/- 0.7), (165.6 +/- 34.3), and (18.1 +/- 1.4) pg/(10(6)cell.24 h). Extracellular VEGF expressions of SW1990, Capan-1, Aspc-1, MiaPaCa-2, Panc-1 and PCT-3 were (1331.1 +/- 67.8), (3902.6 +/- 79.7), (2657.3 +/- 51.9), (1498.3 +/- 4.8), (4696.8 +/- 45.5), and (1200.5 +/- 42.2) pg/(10(6)cell.24 h). Intracellular bFGF expressions of SW1990, Capan-1, Aspc-1, MiaPaCa-2, Panc-1 and PCT-3 were (66.1
