Few studies investigated the biological effects of American grape cultivars. We investigated the metabolic response after acute
consumptionofgrapejuiceorwinefromBordograpes(Vitis labrusca)inaplacebo-controlledcrossoverstudywithfifteenhealthy
volunteers. Blood samples were collected 1 hour after the intake of 100mL of water, juice, or wine to measure TBARS, ABTS,
FRAP, glucose, and uric acid levels. To evaluate differences in cellular response, intracellular reactive species production
(DCFH-DA)andmetabolicmitochondrialviability(MTT)wereassessedafterexposureofhumanneuron-likecells(SH-SY5Y)

-induced intracellular
production of reactive species (RS) and increased the viability of SH-SY5Y cells. In contrast, wine (dealcoholized) exhibited
a per se effect by inducing the production of RS and reducing cell viability. ese results indicate a positive impact of acute
consumption of Bordo juice and wine on human oxidative status, whereas only juice had protective effects against oxidative
stress-induced cytotoxicity.
1. Introduction
Oxidative stress is caused by the insufficient capacity of
biological systems to neutralize the excessive production of
reactivespecies[1],whichleadstooxidativedamageincells.
Neuronalcellsareparticularlysusceptibletoreactiveoxygen
species (ROS) and reactive nitrogen species (RNS) due to
their high metabolic activity, low antioxidant capacity, and
their nonreplicative nature. Furthermore, the abundance of
mitochondria in brain cells increases the generation of re-
active species [2].
Fruits and vegetables have many bioactive compounds
suchaspolyphenols,whichhaveantioxidantpropertieswith
a role in the protection of cellular macromolecules against
oxidativedamageinducedbyROSandRNS[3–5].ereis
increasing evidence that polyphenols may protect cell
constituents against oxidative damage and, therefore, limit
the risk of various degenerative diseases associated with
