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 کاملmitochondrial copy number and d-loop variants in pompe patients
objective: pompe disease is a rare neuromuscular genetic disorder and is classified into two forms of early and late-onset. over the past two decades, mitochondrial abnormalities have been recognized as an important contributor to an array of neuromuscular diseases. we therefore aimed to compare mitochondrial copy number and mitochondrial displacement-loop sequence variation in infantile and ad...
متن کاملA portrait of copy-number polymorphism in Drosophila melanogaster.
Thomas Hunt Morgan and colleagues identified variation in gene copy number in Drosophila in the 1920s and 1930s and linked such variation to phenotypic differences [Bridges CB (1936) Science 83:210]. Yet the extent of variation in the number of chromosomes, chromosomal regions, or gene copies, and the importance of this variation within species, remain poorly understood. Here, we focus on copy-...
متن کاملMitochondrial DNA Copy Number in Peripheral Blood and Melanoma Risk
Mitochondrial DNA (mtDNA) copy number in peripheral blood has been suggested as risk modifier in various types of cancer. However, its influence on melanoma risk is unclear. We evaluated the association between mtDNA copy number in peripheral blood and melanoma risk in 500 melanoma cases and 500 healthy controls from an ongoing melanoma study. The mtDNA copy number was measured using real-time ...
متن کاملMaternal and zygotic sex-specific gene interactions in Drosophila melanogaster.
Sex-lethal (Sxl) is a vital, X-chromosome gene involved in Drosophila sex determination. The most striking aspect of the phenotype of daughterless (da), an autosomal maternal-effect mutation, may be explained by effects on the functioning of the Sxl gene in the zygote. In this paper, new aspects of interactions between various combinations of Sxl and da alleles are explored in order to understa...
