LncRNA TUG1 regulates autophagy-mediated endothelial-mesenchymal transition of liver sinusoidal endothelial cells by sponging miR-142-3p.

ABSTRACT: Accumulating evidence indicates that competing endogenous RNA networks play a critical role in cirrhosis progression. However, their biological role and regulatory mechanisms in liver sinusoidal endothelial cells (LSECs) have not been explored. Here, we exposed LSECs to starvation and lipopolysaccharide (LPS) treatment and assessed changes in TUG1 and miR-142-3p expression, autophagy, and endothelial-mesenchymal transition (EndMT). We confirmed the effects of targeted binding between miR-142-3p and TUG1 or ATG5 by luciferase activity and radio-immunoprecipitation assay. Using an in vivo rat model of cirrhosis, we evaluated autophagy and EndMT in LSECs by immunofluorescence co-localization and immunohistochemical staining. The diagnostic efficiency of miR-142-3p and LPS were determin
