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

, 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.

No excess of mitochondrial DNA deletions within muscle in progressive multiple sclerosis [PDF]

, 2013
Mitochondrial dysfunction is an established feature of multiple sclerosis (MS). We recently described high levels of mitochondrial DNA (mtDNA) deletions within respiratory enzyme-deficient (lacking mitochondrial respiratory chain complex IV with intact ...

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

Genomics & 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

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.
