mtDNA

From regulating each other’s gene expression to encoding different parts of the same proteins, the two genome types in every eukaryotic cell are far from independent.

Interactions between mitochondrial and nuclear genomes have further-reaching effects on physiological function, adaptation, and speciation than previously appreciated.

The recent discovery of 17 people who have inherited maternal and paternal lines of mitochondrial DNA has major ramifications for medical and ancestry research.

A transgenic approach allows researchers to collect the organelles from specific cells in nematodes with unprecedented efficiency.

Adding a fusion gene to certain mitochondria in C. elegans enables researchers to collect and analyze them.

The findings contradict what has been observed in humans.  

In response to short DNA fragments, lymphocytes release mitochondrial DNA that helps trigger an immune response.

Mitochondrial DNA in Neanderthal bone suggests humans first left Africa earlier than previously thought.

Pronuclear transfer can reduce the risk of transferring defective mitochondria, a study shows.  

Rick Harrison, an evolutionary biologist known for his research on speciation, has passed away at age 70.

Experts from the US National Institute of Medicine outline their conditional approval of clinical research on mitochondrial replacement techniques.
