细胞实验 |
细胞系 | DO4, MM415, MM485, SK-MEL-2, MaMel30I and MaMel27II |
方法 | cells were plated in 96-well plates with a density of 4000-8000 cells per well and incubated for 24 h at 37 °C with 5% C02. Then cells were incubated with increasing drug concentrations and their combinations. Cell viability was measured with the CellTiter-Glo (CTG) Luminescent Cell Viability Assay (Promega; Madison, Wisconsin, USA) according to the manufacturer’s protocol. Luminescence was measured on the SynergyHT plate reader (BioTek, Vermont, USA) using Gen5 software (Version 1.11.5). For apoptotic assays, cells were plated in 12-well plates and treated with DMSO, trametinib, metformin or combinations. After 72hrs apoptosis was assessed using the Dead Cell Apoptosis Kit with Annexin V Alexa Fluor 488 & Propidium Iodide according to the manufacturer’s protocol (Invitrogen; V13241) with the AccuriC6 Flow Cytometer using the CFlow software (Version 1.0.227.4). |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km 系数 | 3 | 6 | 12 | 8 | 5 | 20 |
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。
