Effects of 24-h pretreatment with AS or FS on Nrf2 nuclear localization in HUVECs exposed for 24 h to 32 % O2 (mild hyperoxic conditions) or to 21 % O2 (normoxic conditions). The figure shows a representative image from three independent experiments. Nrf2 bands intensity values were normalized to the corresponding Lamin B values. Results by densitometry are reported as fold change against FS in normoxia and expressed as mean ± SD of at least three independent experiments. *P < 0.05 versus FS-treated cells exposed to normoxic conditions. °P < 0.05 versus FS-treated cells exposed to hyperoxic conditions. § P < 0.05 versus AS-treated cells exposed to normoxic conditions. AS, human serum obtained after Medox® capsules consumption; FS, human serum obtained immediately before Medox® capsules consumption
