Artesunate treatment for 24 h causes asignificant increase in the levels of reactive oxygen species (ROS) in a dose-dependent manner in both c
7、ell lines.Moreover, Western blotting shows that the levels of-H2AX are significantly elevated when cancer cells are treatedwith Artesunate in the higher dose range for 24 h. Artesunate also shows a time-dependent effect on the level ofRAD51 in A2780 and HO8910 cells. In two types of non-malignant ce
8、lls, normal human fibroblasts and immortalizedepithelial cells, FTE-187, the level of RAD51 is not altered by Artesunate. In A2780 cells, the level of RAD51 mRNA isindeed decreased by the addition of Artesunate, in a dose-dependent manner. Correspondingly, the promoter activityof RAD51 is significan
9、tly inhibited by Artesunate. In contrast, the RAD51 mRNA level in H8910 cells is not affected byArtesunate3.体内研究 Tumor growth is significantly reduced in the group receiving combined treatment of Artesunate and cisplatin(P0.01). In comparison, Artesunate alone has no significant effect on the growth

They are for reference only.Cell Assay 3 A2780 and HO8910 cells are cultured in RPMI 1640, Normal human fibroblasts (NHF) in DMEM, and FTE-187 in M199,supplemented with 10% fetal bovine serum, 100 units/mL penicillin
13、, and 100 mg/mL streptomycin. All the cells areincubated in a humidified atmosphere of 95% air and 5% CO2. Artesunate is applied to the cultured cells at theconcentration of 0, 5, 10, 25, or 50 g/mL for various periods. The reactive oxygen species (ROS) production followingArtesunate treatment is de

Cells are resuspended using preserving fluid and analyzed with a FACSCanto II.The peak excitation wavelength for oxidized CM-H2DCFDA is 490 nm and emission is 530 nm3.MCE has no
