a The pathway of citrate metabolism and transport. b Expression of Idh3α, Sdhα, Slc25a1, and Acly mRNA in the lungs 12 h after LPS or normal saline treatment. The fold changes were calculated relative to the saline group (n = 6–8). cf Representative immunoblots of lung tissue lysates 12 h after LPS treatment showing decreased protein levels of IDH3α and CIC (n = 6 mice per group) and increased citratemt but not citratecy in the lungs of ALI mice (n = 8–9 mice per group). gj IDH3α and CIC mRNA and protein levels were downregulated, whereas increased citratemt was observed in LPS-treated MLE12 cells (n = 3). The data are shown as the mean ± SD. *P < 0.05, **P < 0.01, and ***P < 0.001.
