| Research Abstract |
Resveratrol has attracted wide attention because of its antioxidant, anti-apoptotic and anti-inflammatory effects. We have previously reported that resveratrol inhibits acetylcholine-induced catecholamine secretion and synthesis through suppressing ion influx in cultured bovine adrenal medullary cells. In this study, we examined the effect of resveratrol on noradrenaline (NA) transporter, which is also known to be the cellular targets of antidepressants. Resveratrol stimulated NA uptake by SK-N-SH cells at low concentration, it was inhibited NA uptake at high concentration against this. Kinetics analysis of the effect of resveratrol on NA transport in SK-N-SH cells indicated that they decreased the Vmax of NA transport with little or no change in Km. Scatchard analysis of nisoxetine binding to plasma membranes showed that resveratrol did not affect the Bmax and the Kd.
The present findings suggest that resveratrol plays a biphasic role in the regulation of neuronal NA transport.
