miR-96 and miR-330 overexpressed and targeted AQP5 in lipopolysaccharide-induced rat lung damage of disseminated intravascular coagulation

Disseminated intravascular coagulation (DIC) is a severe clinical condition that can lead to or aggravate the development of multiple organ dysfunction syndrome. Of all types of organ damage, lung damage is the most frequent and most severe. In DIC patients, lung damage is primarily characterized by pulmonary edema. Aquaporin (AQP) 5 is the chief AQP in the lungs and it plays a key role in many processes, including water transport in normal and abnormal lungs. Here we demonstrate that expression of AQP5 and two microRNAs, miR-96 and miR-330, in rat lung of lipopolysaccharide (LPS)-induced DIC. We also show that both miR-96 and miR-330 can regulate the expression of AQP5 by binding with its 3'-untranslated region (UTR) by luciferase activity assay. These results suggest that microRNAs are involved in lung damage in LPS-induced rat DIC and can be a potential target for molecular therapy.
