Receptor-Interacting Serine/Threonine Kinase 3 (RIP3) –Mixed Lineage Kinase Like Protein (MLKL)–Mediated Necroptosis Contributes to Ischemia-Reperfusion Injury of Steatotic Livers
Increased hepatic ischemia-reperfusion (IR) injury in steatotic livers is a major reason for rejecting the use of fatty livers for liver transplantation. Necroptosis is implicated in the pathogenesis of fatty liver diseases. Necroptosis is regulated by three key proteins: receptor-interacting serine/threonine kinase 1 (RIP1; official name RIPK1), RIP3, and mixed lineage kinase like protein (MLKL). Here, we found that western diet (WD) induced marked steatosis in mouse livers, which was associated with the inhibition of hepatic proteasome activities and increased levels of key necroptosis proteins.
