Liver-specific TH activity in NAFLD and NASH

Prof. Dr. med. Knut Mai,  Prof. Dr. med. Frank Tacke

We aim to define the effects of local TH availability in the development and progression of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). Deiodinases are key enzymes involved in the local activation and inactivation of TH. We will analyse the effect of genetic deletion and siRNA-based knockdown of deiodinases in appropriate rodent models, and study the modulation of genes implicated in local TH availability in human liver samples with different degrees of liver pathology.
