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 ...

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 ...

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 ...

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 ...

A high-throughput single-cell single-mitochondrial genome sequencing technology known as iMiGseq has provided new insights into mutations of mitochondrial DNA (mtDNA) and offers a platform for ...

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 ...

Mitochondrial genomes are not uniform across cells of the body as previously believed, but vary between different tissue types, according to a study published online today (March 3) in Nature. Image: ...
