DNA Damage and Base Excision Repair in Mitochondria and Their Role in Aging

open access: yesJournal of Aging Research, 2011
During the last decades, our knowledge about the processes involved in the aging process has exponentially increased. However, further investigation will be still required to globally understand the complexity of aging.

Mitochondrial DNA sequencing of a wet-collection syntype demonstrates the importance of type material as genetic resource for lantern shark taxonomy (Chondrichthyes: Etmopteridae)

open access: yesRoyal Society Open Science, 2021
After initial detection of target archival DNA of a 116-year-old syntype specimen of the smooth lantern shark, Etmopterus pusillus, in a single-stranded DNA library, we shotgun-sequenced additional 9 million reads from this same DNA library.

Nucleic acids and protein synthesis in cancer cell mitochondria. I. Nucleic acids in rat hepatoma mitochondria [PDF]

open access: yes, 1967
The contents of nucleic acids in rat liver and hepatoma mitochondria and the physico-chemical properties on DNA's isolated from these mitochondria were comparatively investigated. The results are briefly summarized as follows. 1.

DNA-PKcs promotes sepsis-induced multiple organ failure by triggering mitochondrial dysfunction

open access: yesJournal of Advanced Research, 2022
Introduction: Multiple organ failure is the commonest cause of death in septic patients. Objectives: This study was undertaken in an attempt to elucidate the functional importance of DNA-dependent protein kinase catalytic subunit (DNA-PKcs) on ...

Ergosterol reduction impairs mitochondrial DNA maintenance in S. cerevisiae [PDF]

open access: yes, 2019
Sterols are essential lipids, involved in many biological processes. In Saccharomyces cerevisiae, the enzymes of the ergosterol biosynthetic pathway (Erg proteins) are localized in different cellular compartments.

A rapid and efficient method for enriching mitochondrial DNA from plants

open access: yesMitochondrial DNA. Part B. Resources, 2018
Current mitochondrial purification techniques are tedious and protracted due to their emphasis on recovering physiologically active mitochondria. However, for studies that are exclusively interested in isolating mitochondrial DNA (mtDNA) for applications

Expression of catalytic mutants of the mtDNA helicase Twinkle and polymerase POLG causes distinct replication stalling phenotypes. [PDF]

open access: yes, 2007
The mechanism of mitochondrial DNA replication is a subject of intense debate. One model proposes a strand-asynchronous replication in which both strands of the circular genome are replicated semi-independently while the other model proposes both a ...

Mitochondrial DNA-related Disorders

open access: yesBioscience Reports, 2007
Mitochondrial diseases are a group of disorders due to a mitochondrial respiratory chain deficiency. They may depend on mitochondrial genome (mtDNA-related disorders) as well as on a nuclear genome defect (nDNA-related disorders). mtDNA-related disorders encompass an increasing number of clinical pictures associated with more than 250 different ...

The Role of Mitochondria in Human Fertility and Early Embryo Development: What Can We Learn for Clinical Application of Assessing and Improving Mitochondrial DNA?

open access: yesCells, 2022
Mitochondria are well known as ‘the powerhouses of the cell’. Indeed, their major role is cellular energy production driven by both mitochondrial and nuclear DNA.

A Mitochondrial Health Index Sensitive to Mood and Caregiving Stress. [PDF]

open access: yes, 2018
BACKGROUND:Chronic life stress, such as the stress of caregiving, can promote pathophysiology, but the underlying cellular mechanisms are not well understood.
