The accessory subunit of mitochondrial DNA polymerase {gamma} determines the DNA content of mitochondrial nucleoids in human cultured cells [PDF]

open access: yes, 2009
The accessory subunit of mitochondrial DNA polymerase γ, POLGβ, functions as a processivity factor in vitro. Here we show POLGβ has additional roles in mitochondrial DNA metabolism.

Molecular mechanisms of mitochondrial DNA release and activation of the cGAS-STING pathway

open access: yesExperimental and Molecular Medicine, 2023
Inflammatory diseases: Understanding mitochondrial DNA release Cytosolic DNA activates the cGAS-STING pathway which mediates inflammation and antiviral response. One source of cytosolic DNA is ‘self ‘ DNA, such as mitochondrial DNA.

Regional differences in mitochondrial DNA methylation in human post-mortem brain tissue

open access: yesClinical Epigenetics, 2017
Background DNA methylation is an important epigenetic mechanism involved in gene regulation, with alterations in DNA methylation in the nuclear genome being linked to numerous complex diseases.

Mitochondrial DNA lineages of Italian Giara and Sarcidano horses [PDF]

open access: yes, 2014
Giara and Sarcidano are 2 of the 15 extant native Italian horse breeds with limited dispersal capability that originated from a larger number of individuals. The 2 breeds live in two distinct isolated locations on the island of Sardinia. To determine the

Neuropathic Pain as Main Manifestation of POLG-Related Disease: A Case Report

open access: yesFrontiers in Neurology, 2022
Mutations in nuclear-encoded genes that are involved in mitochondrial DNA replication and maintenance (e.g., POLG) have been associated with chronic progressive external ophthalmoplegia (CPEO) phenotype.

Mitochondrial DNA Backgrounds Might Modulate Diabetes Complications Rather than T2DM as a Whole [PDF]

open access: yes, 2011
Mitochondrial dysfunction has been implicated in rare and common forms of type 2 diabetes (T2DM). Additionally, rare mitochondrial DNA (mtDNA) mutations have been shown to be causal for T2DM pathogenesis.

Analysis of Nuclear Mitochondrial DNA Segments of Nine Plant Species: Size, Distribution, and Insertion Loci [PDF]

open access: yesGenomics & Informatics, 2016
Nuclear mitochondrial DNA segment (Numt) insertion describes a well-known phenomenon of mitochondrial DNA transfer into a eukaryotic nuclear genome. However, it has not been well understood, especially in plants. Numt insertion patterns vary from species

Plant mitochondrial DNA

open access: yesFrontiers in Bioscience, 2017
Plants possess mitochondrial genomes that are large and complex compared to animals. Nearly all animal mitochondrial genomes are about 16.5. kbp in length, whereas plant mitochondrial genomes range between 200-2,000 kbp. This is curious if we assume modern mitochondria originated from a common alpha-proteobacterial ancestor.
