Cell cycle was measured with cell cycle flow cytometry and a living cell assay. Apoptosis and terminal deoxynucleoitidyl transferase-mediated dUTP nick end labeling assays were performed to detect the apoptosis of MCF-7 cells induced by ophiopogonin D. Finally, Western blotting was used to explore the mechanism. RESULTS： Exposure of cells to ophiopogonin D resulted in marked decreases in viable cells and colony formation with a dose-dependent manner. Treatment of these cells with ophiopogonin D also resulted in cell cycle arrest at the G2/M phase, and increased apoptosis. Mechanistically, ophiopogonin D-induced G2/M cell cycle arrest was associated with down-regulation of cyclin BI. Furthermore, activation of caspase-8 and caspase-9 was involved in ophiopogonin D-induced apoptosis. CONCLUSION： The data suggested that ophiopogonin D inhibits MCF-7 cell growth via the induction of cell cycle arrest at the G2/M phase.展开更多

However, researchers have paid little attention to the effect of ultrafiltration membrane on traditional medicines chemical constituents. In this work, Ophiopogon japonicus(L.f) Ker-Gawl. was used as an example to illuminate the influence of ultrafiltration with different material and molecular weight cut-off(MWCO) membrane on natural chemical constituents as measured by ultra-fast liquid chromatography coupled with ion trap time-of-flight mass spectrometry(UFLC-IT-TOF/MS). Our results indicated that ultrafiltration membrane significantly impacted homoisoflavonoids, especially homoisoflavonoids that were almost completely retained on the polyethersulfone(PES) membrane. We also found that the larger number of aglycone hydroxy and sugar moiety in steroid saponins, the higher the transmittance. Furthermore, the passage rate(%) of ophiogenin type saponins was higher than that of others. The possible adsorptive mechanisms were hydrogen bonding, hydrophobic interactions, and benzene ring interaction by π-π stacking. In conclusion, it is crucial to choose appropriate ultrafiltration membrane based on the characteristics of produce products for application of ultrafiltration technique.展开更多
