Objective: To observe the effects of triptolide on cell proliferation,cell cycle and cell apoptosis in human multiple myeloma RPMI-8226 cells in vitro, and explore the mechanisms.
Methods: The effect of triptolide on the growth of RPMI-8226 cells was studied by 3-(4,5-dimethyl-2-thiazolyl)-2,5 diphenyl-2H-tetrazolium (MTT) assay. Apoptosis was detected through Annexin V-FITC/PI double-labeled cytometry and Hoechst33258 staining assay. A propidium iodide method was used to study cell cycle distribution b...
