E3 ubiquitin ligase NEDD4-1 suppresses acetaminophen-induced liver injury in mouse by targeting the degradation of VDAC1

Acetaminophen (APAP) overdose provokes various degrees of liver injury, whose pathogenesis involves multiple pathological events, such as mitochondrial damage and necrosis. E3 ubiquitin ligase neural precursor cell expressed developmentally downregulated 4-1 (NEDD4-1) plays vital roles in regulating a wide spectrum of physiological processes, and has been implicated in the pathogenesis of numerous liver disease. However, studies about the regulation of NEDD4-1 on APAP-induced liver injury (AILI) is still deficient. Thus, the aim of this study is to determine whether and how NEDD4-1 plays a role in AILI. Thus, we performed transcriptomic studies comparing liver samples of APAP-treated Flox or APAP-treated hepatocyte-specific Nedd4-1 (HepKO) deficiency mice, RNA-seq was conducted on total RNA isolated from livers of Flox or HepKO mice treated with 300 mg/kg APAP for 24 h; n = 3 per group.
