Fig. 4. Correlation between NO and ROS levels (A), ROS levels (B), and protein expression of Nrf2 (C) and HO-1 (D). Data are presented as the mean±standard error obtained from three independent experiments. Values not sharing common letters (a-d) are significantly different among the groups at P<0.05. ROS, reactive oxygen species; NO, nitric oxide; LPS, lipopolysaccharide; GYW, green yuja peel hot water extract; GYE, green yuja peel ethanol extract; Nrf2, nuclear factor erythroid 2-related factor 2; HO-1, heme oxygenase-1.
