Pexophagy and Oxidative Stress: Focus on Peroxisomal Proteins and Reactive Oxygen Species (ROS) Signaling Pathways [PDF]
AntioxidantsPeroxisomes generate reactive oxygen species (ROS) and also play a role in protecting cells from the damaging effects of such radicals. Dysfunctional peroxisomes are recognized by receptors and degraded by a selective type of macroautophagy called ...

Inhibition of BRD4 Promotes Pexophagy by Increasing ROS and ATM Activation
Cells, 2022 Although autophagy regulates the quality and quantity of cellular compartments, the regulatory mechanisms underlying peroxisomal autophagy (pexophagy) remain largely unknown.

Peroxisome Proliferator Activator α Agonist Clofibrate Induces Pexophagy in Coconut Oil-Based High-Fat Diet-Fed Rats [PDF]
BiologyPeroxisomes are crucial for fatty acid β-oxidation in steatosis, but the role of pexophagy—the selective autophagy of peroxisomes—remains unclear. This study investigated the effects of the peroxisome proliferator-activated receptor-α (PPARα) agonist ...

Energy Charge as an Indicator of Pexophagy in Pichia pastoris
Frontiers in Microbiology, 2017 Pichia pastoris is a good model for pexophagy research owing to its diverse pexophagy modes (macropexophagy and micropexophagy) exhibited during carbon-source shift from methanol to other carbon sources. The critical condition that triggers activation of

Retromer Regulates Macro‐ and Micro‐Autophagy via Distinct Vacuolar Proteases in the Rice Blast Fungus [PDF]
Advanced ScienceThe vacuole degrades and recycles endocytic and autophagic cargos, while the retromer complex sorts cargos from the endosomes to the trans‐Golgi network or the plasma membrane, thus preventing unnecessary vacuolar degradation.
