![]() 2013, 2015a, b Gao and Goodman 2015 Costello et al. To fulfil their multiple functions, peroxisomes need to communicate and cooperate with other organelles, including mitochondria, the endoplasmic reticulum (ER) or lipid droplets (Schrader et al. Peroxisomes perform important functions in hydrogen peroxide and lipid metabolism rendering them essential for human health and development (Wanders and Waterham 2006). ![]() Peroxisomes are ubiquitous and dynamic single membrane-bound organelles in eukaryotic cells, that-similar to mitochondria-show an oxidative type of metabolism. The importance of our findings for the peroxisome-mitochondria redox relationship and the interpretation of in cellulo and in vivo studies with rotenone, which is widely used to study Parkinson’s disease, are discussed. Rotenone also induced alterations in mitochondrial morphology, which-in contrast to its effect on peroxisomes-were dependent on the generation of ROS but independent of its microtubule-active properties. However, this effect is related to its microtubule-destabilising activity rather than to the generation of oxidative stress. We show that rotenone treatment of COS-7 cells alters peroxisome morphology and distribution. Here, we investigated the effect of the mitochondrial complex I inhibitor rotenone on peroxisomal and mitochondrial membrane dynamics. Whereas the generation of peroxisome-derived oxidative stress can affect mitochondrial morphology and function, little is known about the impact of mitochondria-derived oxidative stress on peroxisomes. Their interplay and role in ROS signalling are supposed to impact on age-related and degenerative disorders.
