摘 要:Objective To investigate the effects of sulindac metabolites on proliferation and apoptosis in the human umbilical vein endothelial cell line ECV304 in vitro Methods The proliferation profile of ECV304 was determined by methyl thiazolyl tetrazolium (MTT) method Cell cycle distribution, apoptosis and the ultrastructure of ECV304 were detected by flow cytometry (FCM) and electron microscopy, respectively Results MTT assay showed that the sulfide inhibited the proliferation of ECV304 and its effect was dose dependent; the IC 50 was 200 μmol/L FCM showed that the sulfide changed cell cycle distribution The cell cycle distribution was as follows: G 1 phase (control group 77 74%±1 58%; sulfone group 75 63%±2 12%; sulfide group 46 12%±1 60%); S phase (control group 13 64%±1 22%; sulfone group 16 40±2 30%; sulfide group 27 26%±2 08%); G 2 M phase (control group 8 61%±0 67%; sulfone group 7 98%±0 49%; sulfide group 26 62%±3 54%) The apoptosis rates in the control group, sulfone group and sulfide group were 6 08%±3 39%, 4 81%±2 14% and 51 90%±5 67%, respectively Sulfide reduced the proportion of G 1 phase, increased the proportion of S phase, G 2 M phase and the apoptosis rate significantly ( P 0 01, vs control) In the sulfide treated cells, there were nuclear fragmentation and chromosomal condensation, shrinkage of the cell and loss of contact with neighboring cells Apoptotic bodies were observed Sulfone showed no effect on cell proliferation, cell cycle distribution or cell morphology Conclusions Sulfide can significantly reduce the proliferation of ECV304, change the cell cycle distribution and arrest cells in G 2 M phase where apoptosis may be induced Sulfone has no such effects on this cell line
