Effects of dietary resveratrol supplementation during gestation and lactation of sows on Sirt1, Nrf2-Keap1, NFκB-p65 and p-NFκB-p65 protein expression in placenta. Con, control treatment; Res, resveratrol treatment; a Sirt1 protein expression; b Keap1 and Nrf2 protein expression; c NFκB-p65 and p-NFκB-p65 (Ser536) protein expression; Con, control treatment; Res, resveratrol treatment; Nrf2, Nuclear factor E2-related factor 2; Keap1, Kelch-like ECH associated protein 1; NFκB, nuclear factor kappa B; p-NFκB, phosphorylated NFκB. All values are expressed as means ± SEM (n = 6). GAPDH was used as the internal control. *P < 0.05, **P < 0.01
