细胞系 | MZ-CRC-1 and TT cells |
方法 | Cell viability and motility assays For viability, MZ-CRC-1 and TT cells were seeded in quadruplicate in 96-well plates (10,000 cells per well) in culture media with 2.5% and 4% FBS, respectively. After 24 hours, cells were treated with the indicated compounds. At the indicated time point, cells were incubated for 3 hours with 10 μL of CellTiter96 AQueous One solution in 100 μL of culture media (Promega) and absorbance was measured at 490 nm. For migration assays, Transwell inserts with membranes of 8 μmol/L pore size (Corning-Costar) were used. Membranes were coated with 10 μg/mL collagen and kept at 4°C overnight. Cells were serum starved for 8 hours, detached by trypsin, and counted by hemocytometer. A total of 1 × 105 cells were plated in the upper chambers in serum-free medium, containing the vehicle or the indicated compounds (rapamycin: 100 nmol/L; everolimus/Rad001: 100 nmol/L, and Torin 2: 100 nmol/L). The lower chambers were filled with MZ-CRC-1 and TT culture media containing 2.5% and 4% FBS, respectively, supplemented with 20 ng/mL EGF (Sigma). After 24 hours, cells were fixed in methanol and stained with hematoxylin. Cells on the top surface of the membranes were wiped off with cotton swabs. Membranes were removed from the inserts, placed on microscope slides, and images acquired by Scanscope. Migrated cells were counted and the number of migrated cells per mm2 was calculated. |

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,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
