Baicalein induced apoptosis in MCF-7 cells.
Notes: MCF-7 cells were treated with 0, 50, 100 µM of baicalein alone and 100 μM of baicalein in the presence of Neo (100 μM) pretreatment for 24 h before the cells were double stained with Annexin V/PI and followed by flow cytometric analysis. All data were expressed as the means ± SD of values from triplicate experiments. **P<0.01 and ***P<0.001 versus untreated group; ###P<0.001 for the significance between the groups with or without Neo pretreatment.
