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 کاملWild-Type Mitochondrial DNA Copy Number in Urinary Cells as a Useful Marker for Diagnosing Severity of the Mitochondrial Diseases
The genotype-phenotype relationship in diseases with mtDNA point mutations is still elusive. The maintenance of wild-type mtDNA copy number is essential to the normal mitochondrial oxidative function. This study examined the relationship between mtDNA copy number in blood and urine and disease severity of the patients harboring A3243G mutation. We recruited 115 A3243G patients, in which 28 were...
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...
