Figure Lengend Snippet: Effects of SA supplementation on the JNK/p38/PPAR-γ-NF-κB pathway and the expressions of the oxidation-related genes of the lung tissues. The protein expressions of JNK, p38, NF-κB, and PPAR-γ were tested by western blot analysis ( A , B ). Effects of SA supplementation on the protein levels of oxidation-related genes (HO-1 and NQO1) ( C , D ). CON: control; LPS: lipopolysaccharide; LPS + 50 SA: LPS + 50 mg/kg/day SA; LPS + 100 SA: LPS + 100 mg/kg/day SA; SA: sialic acid. The data are expressed as mean ± SD. CON group vs. LPS group or LPS group vs. LPS + 50 SA group and LPS + 100 SA group. * p < 0.05. ** p < 0.01. # p > 0.05.

Figure Lengend Snippet: Effects of SA supplementation on the p38/JNK and Nrf2 pathways in LPS-induced HUVEC cells. HUVEC cells were pretreated with different dosages of SA (25, 50, and 100 μg/mL) for 2 h and then treated with LPS for 10–12 h. The total protein was obtained from the cells, and the protein expressions of p38, p-p38, JNK, and p-JNK were determined by western blot analysis ( A , B ). The effects of SA supplementation on the Nrf2 pathway ( C , D ). LPS: lipopolysaccharide; SA: sialic acid. Data are presented as the mean ± SD of three independent experiments. CON group vs. LPS group or LPS group vs. 25, 50, and 100 μg/mL SA group. * p < 0.05, ** p < 0.01. # p > 0.05.

Figure Lengend Snippet: Schematic representation of the protective effect and possible molecular mechanisms of SA on ALI. SA exerted a protective effect against LPS-induced ALI via ameliorating inflammation and oxidative damage, which worked mainly through regulation of the JNK/p38-NF-κB/AP-1 and Nrf2 signaling pathways. ALI: acute lung injury; HUVEC: human umbilical vein endothelial cells; LPS: lipopolysaccharide; SA: sialic acid.
