Chemical Characterization, Free Radical Scavenging, and Cellular Antioxidant and Anti-Inflammatory Properties of a Stilbenoid-Rich Root Extract of Vitis vinifera
(a) HO-1 mRNA levels in Huh7 liver cells following 6 h of incubation with the root extract of Vitis vinifera compared to untreated control cells. Resveratrol (Resv., 25 µM) was used as positive control. Data are means + SEM of at least three experiments. indicates significant differences compared to untreated control; , Student’s -test, and indicates significant differences compared to untreated control cells; . (b) Western blotting of HO-1 in Huh7 whole cell extracts following 24 h of incubation with the root extract of Vitis vinifera. Resveratrol (Resv., 25 µM) was used as positive control and GAPDH was used as loading control. One representative Western blot out of three is shown.
