Effect of propofol on dopamine uptake by dopamine transporter in Chinese hamster ovary cells / 中华麻醉学杂志

Objective To determine if propofol can affect uptake of dopamine ( DA) by dopamine transporter (DAT) . Methods Chinese hamster ovary (CHO) cells in which DAT was highly expressed were incubated with H-dopamine in the presence or absence of propofol. Uptake of H-DA was measured. The kinetic parameters Vmax and Km were calculated. Results Propofol significantly inhibited uptake of DA by DAT in CHO cells as compared with the control ( P
