網頁This study aimed to investigate the effects and underlying mechanisms of uric acid on development of NAFLD and insulin resistance. Methods: We initially analyzed the impact of uric acid on the development of hepatic steatosis and insulin resistance in mice and in two cell models, HepG2 and L02. 網頁Mechanistically, amino acid binding allosterically activates Ubr1 by alleviating Ubr1's auto-inhibition. In the absence of amino acids, or when the amino acid-binding capacity of Ubr1 is diminished, Ubr1-mediated Plin2 degradation is inactivated, leading to steatosis. Conclusions: We identified Ubr1 as an amino acid sensor regulating Plin2 ...
