Update information. Drug Induced-liver injury (DILI) is a significant cause of acute liver failure (ALF) and liver transplantation in the Western world. APAP overdose is a main contributor of DILI, leading to hepatocyte cell death through necrosis. Herein, we identified that neddylation, an essential post-translational modification involved in the mitochondria function, was upregulated in liver biopsies from APAP-induced liver injury (AILI) patients and in mice treated with an APAP overdose. MLN4924, an inhibitor of the NEDD8 activating enzyme (NAE-1), ameliorated necrosis and boost liver regeneration in AILI. To understand how neddylation interferes in AILI, whole-body biotinylated NEDD8 (bioNEDD8) and Ubiquitin (bioUB) transgenic mice were investigated under APAP overdose with and without MLN4924. The CDP-DAG synthase TAM41, responsible to produce cardiolipin essential for mitochondrial activity, was found modulated under AILI and restoring its levels by inhibiting neddylation. Understanding this ubiquitin-like crosstalk in AILI is essential for developing promising targeted inhibitors for DILI treatment.
