Redox system and ROS-related disorders in peroxisomes

Abstract

Peroxisomes are essential organelles that help mitigate the oxidative damage caused by reactive oxygen species (ROS) through their antioxidant systems. They perform functions such as α-oxidation, β-oxidation, and the synthesis of cholesterol and ether phospholipids. During the breakdown of specific metabolites, peroxisomes generate ROS as byproducts, which can either be neutralized or contribute to oxidative stress. The relationship between peroxisomal metabolism and ROS-related disorders, including neurodegenerative diseases and cancers, has been studied for decades; however, the exact mechanisms remain unclear. Our review will provide recent insights into the peroxisomal redox system and its association with oxidative stress-related diseases. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
