MicroRNA-31-5p Exacerbates Lipopolysaccharide-Induced Acute Lung Injury via Inactivating Cab39/AMPK Pathway.

Acute lung injury (ALI) and the subsequent acute respiratory distress syndrome remain devastating diseases with high mortality rates and poor prognoses among patients in intensive care units. The present study is aimed at investigating the role and underlying mechanisms of microRNA-31-5p () on lipopolysaccharide- (LPS-) induced ALI. Mice were pretreated with agomir, antagomir, and their negative controls at indicated doses for 3 consecutive days, and then they received a single intratracheal injection of LPS (5 mg/kg) for 12 h to induce ALI.

miRNA-1246 suppresses acute lung injury-induced inflammation and apoptosis via the NF-κB and Wnt/β-catenin signal pathways.

Acute lung injury (ALI) is the common and complicated inflammatory lung disease. MicroRNAs (miRNA) have emerged as novel gene regulatory molecules which play a crucial role in multiple complicated diseases, including ALI. In this study, we aims to identify potential regulatory functions of miRNA-1246 in lipopolysaccharide (LPS)-induced ALI.
