Compatibility between the nuclear (nDNA) and mitochondrial (mtDNA) genomes is important for organismal health. However, its significance for major evolutionary processes such as speciation is unclear, especially in vertebrates. We previously identified a sharp mtDNA-specific sequence divergence between morphologically indistinguishable chameleon populations (Chamaeleo chamaeleon recticrista) ac...
The liver fluke infection-associated intrahepatic cholangiocarcinoma (ICC) is a major liver cancer in Northeast Thailand. The molecular basis of this ICC is poorly understood. To address possible roles of the DNA mismatch repair (MMR) system in ICC carcinogenesis, a fluorescence-labeling PCR/laser scanning technique with high sensitivity was employed to analyze genomic instability in the nuclea...
Correspondence: [email protected] Department of Oncological Sciences, Icahn School of Medicine at Mount Sinai , One Gustave L. Levy place, New York, 10029, USA Full list of author information is available at the end of the article Abstract Eukaryotic cells carry two genomes, nuclear (nDNA) and mitochondrial (mtDNA), which are ostensibly decoupled in their replication, segregation and inherita...
introduction: a number of maternally inherited mitochondrial diseases with distinct clinical phenotypes have been associated with point mutations in mtdna, all of which result in neurologic or neuromuscular disorders. several studies showed that mutations in the trna genes of mtdna could cause mitochondrial disease due to the decreased synthesis of mitochondrial dna coded proteins. materials an...
BACKGROUND Although human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) affect mitochondrial DNA (mtDNA) content and function, comprehensive evaluations of their effects on mitochondria in muscle, adipose tissue, and blood cells are limited. METHODS Mitochondrial DNA quantification, mitochondrial genome sequencing, and gene expression analysis were performed on muscl...
Inheritance of one of three primary mutations at positions 11778, 3460 or 14484 of the mitochondrial genome in subunits of Complex I causes Leber's Hereditary Optic Neuropathy (LHON), a specific degeneration of the optic nerve, resulting in bilateral blindness. It has been unclear why inheritance of a systemic mitochondrial mutation would result in a specific neurodegeneration. To address the n...
the hypothesis that mitochondrial genes may be implicated in susceptibility to multiple sclerosis (ms) is supported by an increasing number of case reports on lebers hereditary optic neuropathy (lhon)-associated mitochondrial dna (mtdna) point mutations in patients with ms. a number of mtdna mutations with primary pathogenic significance for lhon, a maternally inherited disease causing severe b...

The lizard genus Xantusia of southwestern North America has received recent attention in relation to delimiting species. Using more than 500 lizards from 156 localities, we further test hypothesized species boundaries and clarify phylogeographical patterns, particularly in regions of potential secondary contact. We sequenced the entire mitochondrial cytochrome b gene for every lizard in the stu...
