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 ...

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 ...

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 ...

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might ...

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: ...

When a four-year-old boy was brought to the Cincinnati Children’s Hospital Medical Center with fatigue, muscle pain and muscle weakness, doctors suspected there might be something wrong with his ...

Mitochondria, the cell’s powerhouse, exist at the center of cellular biosynthetic pathways and play a major role in energy production, controlling cell death and oxidative stress. Defects in ...

We’re only in the early stages of 2026, and one massive change from last year may have already occurred: there may actually ...

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 ...
