Recent studies have identified 70 oxygenized phosphatidylcholine (PC)-containing epoxy and hydroperoxide groups that are generated in the early phase of acetaminophen (APAP)-induced acute liver injury. In a new study, researchers from the University of Tokyo focused on arachidonate PC and assessed the role of liver-specific LPCAT3 (lysophospholipid acyltransferase 3) on APAP-induced acute liver injury in mice.
