Statins are a class of HMG-CoA reductase inhibitors, which exert cholesterol-lowering and anti-inflammatory effects.Methods: Rosuvastatin (1 mg/kg) was injected intravenously in rats 12 h before lipopolysaccharide (LPS, 10 mg/kg) administration. Eight hours later after LPS challenge, alveolar fluid clearance (AFC) was detected in rats (n = 6– 8). Rosuvastatin (0.3 μmol/mL) and LPS were cultured with primary rat alveolar type II epithelial cells for 8 h.Results: Rosuvastatin obviously improved AFC and attenuated lung-tissue damage in ALI model. Moreover, it enhanced AFC by increasing sodium channel and Na,K-ATPase protein expression. It also up-regulated P-Akt via reducing Nedd4-2 in vivo and in vitro. Furthermore, LY294002 blocked the increase in AFC in response to rosuvastatin. Rosuvastatin-induced AFC was found to be partly rely on sodium channel and Na,K-ATPase expression via the PI3K/AKT/Nedd4-2 pathway.Conclusion: In summary, the findings of our study revealed the potential role of rosuvastatin in the management of ALI/ARDS.Keywords: acute respiratory distress syndrome, rosuvastatin, alveolar fluid clearance, sodium channel, Na,K-ATPases |
