To explore the inhibition of juglone in Qinglongyi on A-549 cells in vitro, MTT assay was used. Laser confocal scanning microscope with AV-PI staining was used to observe apoptotic morphology. Changes of cell cycle are studied by flow cytometry analysis. The result of MTT assay showed that juglone had a marked growth inhibition in A-549 cells and the IC50 is respectively 3.4 times 10-5mol/L, 1.8 times...
To study the effect of saponins of asparagus on apoptosis and the variations of Caspase-8, 9, 3 activity in the process of asparagus induced apoptosis in HepG-2. Cell was administrated with different concentrations of asparagus at different time, the apoptosis rate was determined by FCM with AV-PI staining, the morphology was observed by electron microscopy, caspase-8,9,3 activities was measured by...
The aim of this paper is to investigate the pro-apoptosis effect of isothiocyanates (ITCS) on human gastric adenoma cells SGC-7901 and its mechanism. SGC-7901 was treated with different concentrations of ITCS. MTT assay was used to evaluate the influence of ITCS on cell proliferation. Flow cytometry was used to test reactive oxygen species (ROS) levels, intracellular mitochondrial transmembrane potential...
To observe the effect of solanine on the membrane potential of mitochondria in HepG2 cells and [Ca2+]i in the cells, and to uncover the mechanism by which solanine induces apoptosis. HepG2 cells are double stained with TMRE and Fluo-3/AM, and both the change in membrane potential of mitochondria and that of [Ca2+]i in the cells are observed using LCSM. The results of double staining with TMRE and...
This study analyzed the effect of Asparagus polysaccharides on the migration time of erythrocytes in tumor- bearing organisms. A mouse tumor model was developed in which mice were intraperitoneally injected with high, medium, and low dosages of Asparagus polysaccharides for 7 d. The erythrocytes were collected and prepared into suspensions, and the migration time of cells were measured using high...
