A mitochondrial enzyme, Ak4, strengthens immune defense by promoting mitochondrial DNA synthesis and enhancing macrophage ...

EPFL scientists have discovered that a simple shape change in mitochondria helps cells evenly distribute their mitochondrial ...

A new study from deCODE genetics uses pedigrees and sequence data from 64,806 Icelanders to shed light on the rate and nature of mutations in mitochondrial DNA (mtDNA) and the peculiar dynamics of its ...

One study reported 8 live births from 22 women with pathogenic mtDNA variants who underwent mitochondrial donation through pronuclear transfer. None had signs of mitochondrial disease and heteroplasmy ...

Provide each team with a copy of "The Hunt for mtDNA" student handout. Explain to students what mtDNA is, how it differs from nuclear DNA, and how it is inherited (see Activity Answer for more ...

A new analysis of ancient mitochondrial DNA (mtDNA) from Neanderthal fossils suggests researchers may need to revisit when ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

The vast majority of our DNA—the chromosomes in the nucleus of each cell—is just what you’d expect: a mix of genetic material from both mother and father. But mitochondria are an exception. They ...

You are a forensic scientist recruited to help solve a long-standing "missing persons" case. Mitochondrial DNA, or mtDNA for short, is the key to your success. Take careful notes as your teacher ...
