摘要：
AIM: To study effect of manoalide on apoptosis induced by deprivation of acidic fibroblast growth factor (aFGF) and serum in vascular endothelial cells ( VEC). METHODS: Morphologic changes were observed by light microscopy. Viability was determined by counting the cells that attached to dishes after treatments. DNA fragmentation was analyzed by agarose gel electrophoresis and fluorescence microscopy. RESULTS: The cells deprived of aFGF and serum were exposed to manoalide 1 - 4 mu mol.L-1 for 48 h, detachment and DNA fragmentation of these cells were suppressed. At 7 mu mol.L-1, manoalide promoted detachment and DNA fragmentation of VEC. CONCLUSION: manoalide 2 mu mol L-1 inhibited, but 7 mu mol.L-1 promoted, apoptosis of VEC.
