Regulation of mitochondrial biogenesis.
Although it is well established that physical activity increases mitochondrial content in muscle, the molecular mechanisms underlying this process have only recently been elucidated. Mitochondrial dysfunction is an important component of different diseases associated with aging, such as Type 2 diabetes and Alzheimer's disease. PGC-1alpha (peroxisome-proliferator-activated receptor gamma co-acti...
متن کاملA Review of Mitochondrial Biogenesis and Cellular Response
Abstract Background and Objectives Mitochondrial biogenesis is a complex process involving the coordinated expression of mitochondrial and nuclear genes, the import of the products of the latter into the organelle and turnover of this process. Mitochondrial malfunction or defects in any of the many pathways involved in mitochondrial biogenesis can lead to degenerative diseases and possibly pla...
متن کاملRegulation of PGC-1α, a nodal regulator of mitochondrial biogenesis.
Mechanisms responsible for energy management in the cell and in the whole organism require a complex network of transcription factors and cofactors. Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) has emerged as a master regulator of mitochondrial biogenesis and function, thus becoming a crucial metabolic node. We present an overview of the mechanisms by which PGC-1α is reg...
متن کاملRegulation of Mitoflash Biogenesis and Signaling by Mitochondrial Dynamics
Mitochondria are highly dynamic organelles undergoing constant network reorganization and exhibiting stochastic signaling events in the form of mitochondrial flashes (mitoflashes). Here we investigate whether and how mitochondrial network dynamics regulate mitoflash biogenesis and signaling. We found that mitoflash frequency was largely invariant when network fragmentized or redistributed in th...
متن کاملBiogenesis of mitochondrial proteins.
Numerous components have been identified that participate at various stages in the biogenesis of mitochondria. For many of these components, their specific functions have recently been defined through detailed investigations of the molecular mechanisms underlying protein targeting, translocation across the mitochondrial outer and inner membranes, membrane insertion, suborganellar sorting, and p...
