The Role of 12/15-Lipoxygenase and Its Various Metabolites Generated from Multiple Polyunsaturated Fatty Acids as Substrates in Inflammatory Responses

Abstract

12/15-lipoxygenase (12/15-LOX) is a member of the lipoxygenase family, which can catalyze a variety of polyunsaturated fatty acids (PUFA) to produce different metabolites, such as 12-hydroxyeicosatetraenoic acid (12-HETE), 15-HETE, lipoxin (LX), hepoxilin, resolvin, protectin, and maresins. 12/15-LOX and its metabolites take part in inflammatory responses and mediate related signalling pathways, playing an essential role in various inflammatory diseases. So the definition, catalytic substrates, metabolites of 12/15-lipoxygenase, and their roles in inflammatory responses are reviewed in this article.
