Stress-dependent opposing roles for mitophagy in aging of the ascomycete Podospora anserina
Mitochondrial dysfunction is causatively linked to organismal aging and the development of degenerative diseases. Here we describe stress-dependent opposing roles of mitophagy, the selective autophagic degradation of mitochondria, in aging and life-span control. We report that the ablation of the mitochondrial superoxide dismutase which is involved in reactive oxygen species (ROS) balancing, do...
متن کاملEffect of paraquat-induced oxidative stress on gene expression and aging of the filamentous ascomycete Podospora anserina
Aging of biological systems is influenced by various factors, conditions and processes. Among others, processes allowing organisms to deal with various types of stress are of key importance. In particular, oxidative stress as the result of the generation of reactive oxygen species (ROS) at the mitochondrial respiratory chain and the accumulation of ROS-induced molecular damage has been strongly...
متن کاملMitochondrial quality control in aging and lifespan control of the fungal aging model Podospora anserina.
Aging of biological systems is a fundamental process controlled by a complex network of molecular pathways. In the filamentous fungus Podospora anserina, a model in which organismal aging can conveniently be analysed, mitochondria play a central role. A wide range of relevant pathways were identified that contribute to the maintenance of a population of functional mitochondria. These pathways a...
متن کاملThe Phenoloxidases * of the Ascomycete Podospora
N communication I11 (ESSEH 1966) of this series of papers, eleven loci belongI ing to six different linkage groups are described. These loci not only influence morphological characteristics, but also the formation of melanin pigments in Podospora. A preliminary biochemical analysis of these mutants has shown that at least two of these loci, the unlinked genes zonata and flexuosa, control the sy...
متن کاملModulation of the glyoxalase system in the aging model Podospora anserina: effects on growth and lifespan
The eukaryotic glyoxalase system consists of two enzymatic components, glyoxalase I (lactoylglutathione lyase) and glyoxalase II (hydroxyacylglutathione hydrolase). These enzymes are dedicated to the removal of toxic α-oxoaldehydes like methylglyoxal (MG). MG is formed as a by-product of glycolysis and MG toxicity results from its damaging capability leading to modifications of proteins, lipids...
