细胞实验
细胞系 MKN45, BT474, SNU216 and NCI-N87 cell lines
方法 Cell viability assay Cells were seeded at a density of 2000 cells per well in a 96-well plate and incubated overnight in complete medium. Cells were treated with either trastuzumab, BEZ235, Everolimus, AZD6244 alone, or trastuzumab combined with BEZ235 or Everolimus or AZD6244. After 72 h of incubation, cell viability was determined using the MTS tetrazolium substrate (CellTiter 96 Aqueous One Solution Cell Proliferation Assay, Promega, Madison, WI, USA) following the manufacturer’s instructions. The absorbance was measured at 490 nm using a spectrophotometer. All experiments were repeated three times with at least triplicate readings for each concentration.

动物 A (mg/kg) = 动物 B (mg/kg) ×  动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。

实验结果 Resembling the WB results from the BZA treatment, the inhibitors AG490, NVP-BEZ23 and AZD6244 imitated BZA function, down-regulating the pivotal protein of the JAK/STAT3, PI3K/AKT/mTOR and Ras/Raf/MEK/ERK signal pathways

实验结果 BIM and BAK were obviously released to trigger apoptosis once MCL-1 was suppressed by adding BEZ235 in the presence of ABT-263. Of note, although PUMA was upregulated by BEZ235, less PUMA was bound to MCL-1 than control group due to inhibition of MCL-1.
