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

Experimental 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.

The Mitochondrial Response to DNA Damage

Frontiers in Cell and Developmental Biology, 2021
Mitochondria are double membrane organelles in eukaryotic cells that provide energy by generating adenosine triphosphate (ATP) through oxidative phosphorylation. They are crucial to many aspects of cellular metabolism.

Rapid evolution of animal mitochondrial DNA. [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 1979
Mitochondrial DNA was purified from four species of higher primates (Guinea baboon, rhesus macaque, guenon, and human) and digested with 11 restriction endonucleases. A cleavage map was constructed for the mitochondrial DNA of each species. Comparison of

Nuclear-mitochondrial DNA segments resemble paternally inherited mitochondrial DNA in humans

Nature Communications, 2020
Recent evidence has questioned the dogma of strict maternal transmission of mitochondrial DNA (mtDNA) in humans. Wei et al. saw no evidence of paternal transmission of mtDNA in 11,035 human trios, and show that nuclear-mitochondrial segments (NUMTs) can ...

Mitochondrial DNA: the overlooked oncogenome? [PDF]

BMC Biology, 2019
Perturbed mitochondrial bioenergetics constitute a core pillar of cancer-associated metabolic dysfunction. While mitochondrial dysfunction in cancer may result from myriad biochemical causes, a historically neglected source is that of the mitochondrial ...

Mitochondrial DNA editing: Key to the treatment of neurodegenerative diseases [PDF]

Genes and Diseases
Neuronal death is associated with mitochondrial dysfunction caused by mutations in mitochondrial DNA. Mitochondrial DNA becomes damaged when processes such as replication, repair, and nucleotide synthesis are compromised.

Codon affinity in mitochondrial DNA shapes evolutionary and somatic fitness

bioRxiv, 2023
Somatic variation contributes to biological heterogeneity by modulating cellular proclivity to differentiate, expand, adapt, or die. While large-scale sequencing efforts have revealed the foundational role of somatic variants to drive human tumor ...

Effective differentiation of double negative thymocytes requires high fidelity replication of mitochondrial DNA in an age dependent manner

Frontiers in Immunology, 2023
One of the most proliferative periods for T cells occurs during their development in the thymus. Increased DNA replication can result in increased DNA mutations in the nuclear genome, but also in mitochondrial genomes.
