The Mitochondrial Genome of Arctica islandica; Phylogeny and Variation
Arctica islandica is known as the longest-lived non-colonial metazoan species on earth and is therefore increasingly being investigated as a new model in aging research. As the mitochondrial genome is associated with the process of aging in many species and bivalves are known to possess a peculiar mechanism of mitochondrial genome inheritance including doubly uniparental inheritance (DUI), we a...
متن کاملMitochondrial genome function and maternal inheritance.
The persistence of mtDNA to encode a small subset of mitochondrial proteins reflects the selective advantage of co-location of key respiratory chain subunit genes with their gene products. The disadvantage of this co-location is exposure of mtDNA to mutagenic ROS (reactive oxygen species), which are by-products of aerobic respiration. The resulting 'vicious circle' of mitochondrial mutation has...
متن کاملMitochondrial genome inheritance and replacement in the human germline.
Mitochondria, the ubiquitous power packs in nearly every eukaryotic cell, contain their own DNA, known as mtDNA, which is inherited exclusively from the mother. The number of mitochondrial genomes varies depending on the cell's energy needs. The mature oocyte contains the highest number of mitochondria of any cell type, although there is little if any mtDNA replication after fertilization until...
متن کاملImperceptible senescence: ageing in the ocean quahog Arctica islandica.
The ocean quahog Arctica islandica is the longest-lived of all bivalve and molluscan species on earth. Animals close to 400 years are common and reported maximum live span around Iceland is close to 400 years. High and stable antioxidant capacities are a possible strategy to slow senescence and extend lifespan and this study has investigated several antioxidant parameters and a mitochondrial ma...
متن کاملIs “Basal-like” Carcinoma of the Breast a Distinct Clinicopathologic Entity? A Critical Review with Cautionary Notes
This review deals with studies that have used cDNA microarrays and immunohistochemistry to identify a subtype of breast carcinoma recently known as “basal-like” carcinoma. The key breast carcinoma studies are critically discussed to highlight methodological problems in cohort selection, definitions, interpretation of results, an...
