【 摘 要 】

Basic fibroblast growth factor is increasingly implicated in cellular growth, differentiation, angiogenesis and oncogenesis. In culture, basic fibroblast growth factor greatly improved the growth rate of bovine brain cortex capillary endothelial cells. Down-regulation of protein kinase C by prolonged treatment with phorbol esters prevented the mitogenic effect of basic fibroblast growth factor on capillary endothelial cells. Furthermore, staurosporine, a potent protein kinase inhibitor, showed strong antiproliferative activity against basic fibroblast growth factor-induced endothelial cell growth. Similarly, the chemotaxis effect of basic fibroblast growth factor on capillary endothelial cells was abolished by down-regulation of protein kinase C or by staurosporine treatment. Therefore, it is suggested that protein kinase C could account for part of the angiogenic effect of basic fibroblast growth factor.
