Acute lung injury (ALI) and resultant acute respiratory distress syndrome (ARDS) are detrimental inflammatory disease associated with high rates of morbidity and mortality due to a lack of effective treatment options. Previous study has demonstrated that an inhibition of geranylgeranyl pyrophosphate synthase large subunit 1 (GGPPS1) show a protective effect against ALI. In this study, by using connective map (CMAP), we identified catechin as a potential drug to exhibit similar effects to inhibit GGPPS1. Furthermore, we detected the protective effect of catechin on lipopolysaccharide (LPS)-induced ALI and delineated the underlying mechanism. We found that catechin effectively ameliorated LPS-induced lung inflammation and alleviated the release of cytokines into alveolar space. Notably, miR-182/GGPPS1 signaling pathway was reactivated upon catechin administration, which was essential for the catechin-induced protective effect against ALI. catechin regulates miR-182/GGPPS1 signaling pathway and efficaciously ameliorates LPS-induced acute lung injury in mice model, which provided a promising therapeutic strategy in ALI and ARDS.
