Effect of ginsenoside on the cellular proliferation, apoptosis and cell cycles in LC A549 and HUVEC 304 cell lines / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To determine the effect of ginsenoside on the cellular proliferation, apoptosis and cell cycles in LC A549 and HUVEC 304 cell lines.@*METHODS@#A549 and HUVEC 304 cell lines were cultured with different concentrations of ginsenoside. Cellular proliferation was detected with MTT, apoptosis and cell cycles were checked with Flow Cytometer, and change of microstructure was observed by transmission electron microscope.@*RESULTS@#The apoptosis rate was 29.8% in A549 cell lines after being interfered with ginsenoside at 3 x 10(-6) mol/L, significantly higher than that in the control group ( P < 0.05). No change was observed in the cell cycles after being interfered with ginsenoside. The inhibitive rate of ginsenoside was 12.53% for HUVEC 304 cell line at 1 x 10(-4) mol/L (P < 0.05 ). The cells induced by conditioned medium could be inhibited by ginsenoside, and apoptotic body could be found in cells induced by conditioned medium at 10(-6) mol/L.@*CONCLUSION@#The proliferation of vascular endothelial cell could be inhibited by ginsenoside, and apoptosis could also be found in both tumor cells and cells induced by conditioned medium after being interfered with ginsenoside.
