Low Abundance of the Matrix Arm of Complex I in Mitochondria Predicts Longevity in Mice
ARTICLE Received 24 Jan 2014 | Accepted 9 Apr 2014 | Published 12 May 2014 DOI: 10.1038/ncomms4837 OPEN Low abundance of the matrix arm of complex I in mitochondria predicts longevity in mice Satomi Miwa1, Howsun Jow2, Karen Baty3, Amy Johnson1, Rafal Czapiewski1, Gabriele Saretzki1, Achim Treumann3 & Thomas von Zglinicki1 Mitochondrial function is an important determinant of the ageing process; however, the mitochondrial properties that enable longevity are not well understood. Here we show that optimal assembly of mitochondrial complex I predicts longevity in mice. Using an unbiased high-coverage high-confidence approach, we demonstrate that electron transport chain proteins, especially the matrix arm subunits of complex I, are decreased in young long-living mice, which is associated with improved complex I assembly, higher complex I-linked state 3 oxygen consumption rates and decreased superoxide production, whereas the opposite is seen in old mice. Disruption of complex I assembly reduces oxidative metabolism with concomitant increase in mitochondrial superoxide production. This is rescued by knockdown of the mitochondrial chaperone, prohibitin. Disrupted complex I assembly causes premature senescence in primary cells. We propose that lower abundance of free catalytic complex I components supports complex I assembly, efficacy of substrate utilization and minimal ROS production, enabling enhanced longevity. 1 Institute for Ageing and Health, Newcastle University, Newcastle upon Tyne NE4 5PL, UK. 2 Centre for Integrated Systems Biology of Ageing and Nutrition, Newcastle University, Newcastle upon Tyne NE4 5PL, UK. 3 Newcastle University Protein and Proteome Analysis, Devonshire Building, Devonshire Terrace, Newcastle upon Tyne NE1 7RU, UK.

The pharmacological effects of VPA involve a variety of neurotransmitter and cell signaling systems, but the molecular mechanisms underlying its clinical efficacy is to date largely unknown. In this study, we used the isobaric tags for relative and absolute quantitation shotgun proteomic analysis to screen differentially expressed proteins in VPA-treated SH-SY5Y cells. We identified changes in the expression levels of multiple proteins involved in Alzheimer’s disease, Parkinson’s disease, chromatin remodeling, controlling gene expression via the vitamin D receptor, ribosome biogenesis, ubiquitin-mediated proteolysis, and the mitochondrial oxidative phosphorylation and electron transport chain. -

Mitochondrial Peptide BRAWNIN Is Essential for Vertebrate Respiratory Complex III Assembly

Stroud 2 & ✉ Lena Ho 1,7 1234567890():,; The emergence of small open reading frame (sORF)-encoded peptides (SEPs) is rapidly expanding the known proteome at the lower end of the size distribution. Here, we show that the mitochondrial proteome, particularly the respiratory chain, is enriched for small proteins. Using a prediction and validation pipeline for SEPs, we report the discovery of 16 endogenous nuclear encoded, mitochondrial-localized SEPs (mito-SEPs). Through functional prediction, proteomics, metabolomics and metabolic flux modeling, we demonstrate that BRAWNIN, a 71 a.a. peptide encoded by C12orf73, is essential for respiratory chain complex III (CIII) assembly. In human cells, BRAWNIN is induced by the energy-sensing AMPK pathway, and its depletion impairs mitochondrial ATP production. In zebrafish, Brawnin deletion causes complete CIII loss, resulting in severe growth retardation, lactic acidosis and early death. Our findings demonstrate that BRAWNIN is essential for vertebrate oxidative phosphorylation. We propose that mito-SEPs are an untapped resource for essential regulators of oxidative metabolism. -

Thesis C11orf83, a mitochondrial cardiolipin-binding protein involved in bc1 complex assembly and supercomplex stabilization DESMURS-ROUSSEAU, Marjorie Abstract Cette thèse a permis d'identifier C11orf83, désormais appelé UQCC3, comme étant une protéine mitochondriale ancrée dans la membrane interne. Nous avons constaté l'implication de C11orf83 dans l'assemblage du complexe III de la chaîne respiratoire via la stabilisation du complexe intermédiaire MT-CYB/UQCRB/UQCRQ. Nous avons également prouvé que C11orf83 était associée avec le dimère de complexe III et était détectée dans le supercomplexe III2/IV. Son absence induit une baisse significative de ce supercomplexe et du respirasome (I/III2/IV). La capacité de C11orf83 de lier les cardiolipines, connues pour être impliquées dans la formation et la stabilisation de ces supercomplexes, pourrait expliquer ces résultats. Ainsi, ce travail de thèse en lien avec une récente étude clinique mettant en évidence une déficience du complexe III chez un patient atteint d'une mutation du gène C11orf83 (Wanschers et al., 2014) permet d'améliorer les connaissances sur l'assemblage du complexe III et la compréhension d'une maladie mitochondriale.

Cytochrome c1, the heme-containing component of complex III, mediates the transfer of electrons from the Rieske iron-sulfur protein to cytochrome c c . Cytochrome 1 is present at reduced levels in the skeletal muscle and skin fibroblasts of affected individuals. Moreover, studies on yeast mutants and affected individuals’ fibroblasts have shown that exogenous expression of wild-type CYC1 rescues complex III activity, demonstrating the deleterious effect of each mutation on cytochrome c1 stability and complex III activity. -
Mitochondrial Replacement and Mitonuclear Interactions in the Broadstripe Topminnow (Fundulus Euryzonus)

This is commonly observed in freshwater fish species, such as the Fundulus notatus complex, which is composed of F. notatus, F. olivaceus, and F. euryzonus. The broadstripe topminnow, F. euryzonus, is only found in the Amite and Tangipahoa Rivers in the Lake Pontchartrain drainage, where it overlaps in distribution with F. olivaceus. Previous studies determined that F. euryzonus in the Tangipahoa River system possesses mitochondrial DNA (mtDNA) from F. olivaceus as a result of hybridization between the two species. The goal of this thesis was to re-examine an existing data set of single nucleotide polymorphisms (SNPs) to determine if this mitochondrial discordance has manifested itself in changes in the nuclear genome between populations of F. euryzonus in the Amite and Tangipahoa Rivers. This was conducted using a sliding window analysis to look for genome regions with very high (>0.95) or low (<0.01) weighted fixation index (FST) values and further analyzing regions that included three or more windows in a series. -
Mitochondrial Structure and Bioenergetics in Normal and Disease Conditions
International Journal of Molecular Sciences Review Mitochondrial Structure and Bioenergetics in Normal and Disease Conditions Margherita Protasoni 1 and Massimo Zeviani 1,2,* 1 Mitochondrial Biology Unit, The MRC and University of Cambridge, Cambridge CB2 0XY, UK; [email protected] 2 Department of Neurosciences, University of Padova, 35128 Padova, Italy * Correspondence: [email protected] Abstract: Mitochondria are ubiquitous intracellular organelles found in almost all eukaryotes and involved in various aspects of cellular life, with a primary role in energy production. The interest in this organelle has grown stronger with the discovery of their link to various pathologies, including cancer, aging and neurodegenerative diseases. Indeed, dysfunctional mitochondria cannot provide the required energy to tissues with a high-energy demand, such as heart, brain and muscles, leading to a large spectrum of clinical phenotypes. Mitochondrial defects are at the origin of a group of clinically heterogeneous pathologies, called mitochondrial diseases, with an incidence of 1 in 5000 live births. Primary mitochondrial diseases are associated with genetic mutations both in nuclear and mitochondrial DNA (mtDNA), affecting genes involved in every aspect of the organelle function. As a consequence, it is difficult to find a common cause for mitochondrial diseases and, subsequently, to offer a precise clinical definition of the pathology. Moreover, the complexity of this condition makes it challenging to identify possible therapies or drug targets.
