Effects of RSV and PT on the Nrf2 pathway in the jejunum of IUGR piglets. a The protein levels of nuclear Nrf2 and cellular Keap1 in the jejunum; b The protein levels of NQO1, HO1, SOD1 and SOD2 in the jejunum; c The mRNA abundance of NQO1, HO1, SOD1 and SOD2 in the jejunum. Data were presented as means with standard errors (n = 6). ^aOne-way ANOVA and Tukey’s post hoc test was conducted to determine the significant difference among the groups. ^bKruskal–Wallis non-parametric test followed by pairwise differences in rank sums was conducted to determine the significant difference among the groups. *Significantly different (P < 0.05) between groups. NBW, normal birth weight; IUGR, intrauterine growth retardation; RSV, resveratrol; PT, pterostilbene; Nrf2, nuclear factor erythroid 2-related factor 2; Keap1, Kelchlike ECH-associated protein-1; NQO1, NAD(P)H quinone dehydrogenase 1; HO1, heme oxygenase 1; SOD1, superoxide dismutase 1; SOD2, superoxide dismutase 2
