Assessment of mitochondrial DNA copy number in peripheral blood leukocyte of opiate abusers and healthy individuals
Background: Based on the studies, variation in the mitochondrial DNA (mtDNA) copy number in peripheral blood leukocytes is associated with increased susceptibility to diseases including cancer. Opiate abusers are at high risk for diseases. In this study, we measured the mtDNA copy number in peripheral blood leukocytes in a group of opiate abusers compared with those in healthy individuals. Met...
متن کاملGlobal Genetic Determinants of Mitochondrial DNA Copy Number
Many human diseases including development of cancer is associated with depletion of mitochondrial DNA (mtDNA) content. These diseases are collectively described as mitochondrial DNA depletion syndrome (MDS). High similarity between yeast and human mitochondria allows genomic study of the budding yeast to be used to identify human disease genes. In this study, we systematically screened the pre-...
متن کاملThe role of mitochondrial DNA copy number in mammalian fertility.
Mammalian mitochondrial DNA (mtDNA) is a small, maternally inherited genome that codes for 13 essential proteins in the respiratory chain. Mature oocytes contain more than 150 000 copies of mtDNA, at least an order of magnitude greater than the number in most somatic cells, but sperm contain only approximately 100 copies. Mitochondrial oxidative phosphorylation has been suggested to be an impor...
متن کاملKeratoconus is associated with increased copy number of mitochondrial DNA
PURPOSE To investigate the possible association of oxidative stress with keratoconus (KC), we estimated the changes in relative mitochondrial DNA (mtDNA) content. METHODS The study included 119 patients with KC and 208 controls matched for gender, ethnicity, and systemic disease status. We selected controls who were older than the patients since the mtDNA copy number tends to increase with ag...
متن کاملMitochondrial DNA copy number variation across human cancers
Mutations, deletions, and changes in copy number of mitochondrial DNA (mtDNA), are observed throughout cancers. Here, we survey mtDNA copy number variation across 22 tumor types profiled by The Cancer Genome Atlas project. We observe a tendency for some cancers, especially of the bladder, breast, and kidney, to be depleted of mtDNA, relative to matched normal tissue. Analysis of genetic context...
