Adipocytokine expression associated with miRNA regulation and diagnosis of NASH in obese patients with NAFLD

摘要

Background & AimsNon-alcoholic fatty liver disease (NAFLD) is strongly associated with visceral adiposity. The secretion of adipocytokines from white adipose tissue (WAT) promoting necroinflammation, and/or fibrosis may play important roles in the pathogenesis of non-alcoholic steatohepatits (NASH). In a previous study, reduced expression of a number of miRNA species in WAT concomitant with histological diagnosis of NASH was successfully demonstrated. In this study, we measure the expression of several predicted miRNA regulatory targets relevant to NAFLD and NASH including mTOR, FAS, IL20, SEMA4C, ADAMTS6 and IL13RA. We then examine hepatic receptor expression by immunohistochemical staining and qPCR.
