For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

Gene editing technology allows to introduce and correct disease-linked mitochondrial DNA mutations in liver and skin cells In a step toward treating mitochondrial diseases, researchers in the ...

It did not take long after the discovery of X-rays in the 1890s for scientists to begin exploring the harmful effects of ...

Geneticists looking inside the nuclear genome for mutations that contribute to disease have long relied on a principal known as constraint modeling, which allows researchers to assess the degree of ...

Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular powerhouses are in a 1.5-billion-year-old evolutionary relationship—but ...

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 ...

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 ...

Maintaining mitochondrial DNA (mtDNA) integrity is crucial for cardiomyocyte function, and its disruption plays a significant role in ischemia/reperfusion (I/R) injury. This review sheds light on the ...

A new genetic analysis of Neanderthal remains from Stajnia Cave offers an unusually detailed glimpse into a small group that ...

A remarkable genetic breakthrough has uncovered what may be one of the clearest snapshots yet of a Neanderthal “community” ...
