['To observe the proliferation inhibition, cell cycle, and apoptosis of human glioma cell line SHG-44 treated with different concentration of Schidandrin B and explore the effect of Schidandrin B on glioma SHG-44 cells.', 'Glioma SHG-44 cells were treated with Schidandrin B (0, 50, 100 or 200 μg/mL) for 24, 48, 72 and 96 h, and cells were treated with vehicle as control. Viability of cells were detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis; cell cycle was examined with flow cytometry assay; apoptosis was detected with annexin V assay. Bax and caspase-3 proteins expression were checked by Western blot.', 'MTT analysis showed that viability of glioma SHG-44 cells significantly decreased after exposure to Schidandrin B for the indicated time. Flow cytometry revealed that the number of cells in the sub G'] Does schidandrin B kill tumor cells by initiating apoptosis in glioma SHG-44 cells?
