Hepatic neddylation deficiency triggers fatal liver injury via inducing NF-κB-inducing kinase in mice

Abstract

Dysregulation of the post-translational modification neddylation has been implicated in liver diseases such as fibrosis and hepatocellular carcinoma. Here the authors report that hepatic neddylation deficiency via genetic deletion of NEDD8 Activating Enzyme E1 Subunit 1 (NAE1) causes acute liver failure due to mitochondrial dysfunction and aberrant activation of NF-κB-inducing kinase in mice.
