Organelle dynamics and dysfunction: A closer link between peroxisomes and mitochondria

J Inherit Metab Dis. 2009 Apr;32(2):163-80. doi: 10.1007/s10545-008-1018-3. Epub 2008 Dec 12.


Mitochondria and peroxisomes are ubiquitous subcellular organelles, which fulfil an indispensable role in the cellular metabolism of higher eukaryotes. Moreover, they are highly dynamic and display large plasticity. There is growing evidence now that both organelles exhibit a closer interrelationship than previously appreciated. This connection includes metabolic cooperations and cross-talk, a novel putative mitochondria-to-peroxisome vesicular trafficking pathway, as well as an overlap in key components of their fission machinery. Thus, peroxisomal alterations in metabolism, biogenesis, dynamics and proliferation can potentially influence mitochondrial functions, and vice versa. In this review, we present the latest progress in the emerging field of peroxisomal and mitochondrial interrelationship with a particular emphasis on organelle dynamics and its implication in diseases.
