Method RNA interference
Cell Lines A549 cells
Incubation Time 24 h
Results These findings indicated that Cdc42 played a vital role in the uptake of oxMWCNTs in A549 cells, while Rac1 and RhoA might not be involved in this process.

Method Transwells
Cell Lines MDCK cells
Incubation Time
Results As shown in Figure 9, in the presence of ZCL 278, the transmembrane amount of PTX-NCs was reduced significantly, indicating that Cdc 42 participated in the regulation of the transport of PTX-NCs.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
