New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational ...

Genetic mutations in many forms of ALS lead to early problems with the transport and function of mitochondria, a study found.

The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in ...

Human healthy aging and longevity are complex phenomena influenced by a dynamic interplay of genetic, epigenetic, metabolic, immune, and environmental factors.

By analyzing ancient and modern DNA, scientists are uncovering the genetic origins of the Greek people, shaped over millennia ...

Researchers from Khalifa University, Saudi Arabia, working with regional and international collaborators, have examined Yemeni DNA to reveal how migrations from the Levant, Arabia, and East Africa ...

To see whether mitochondrial (mt) haplogroup U – a heritable profile of mitochondrial DNA that has been tied to aging-related conditions – significantly predicts greater GWI severity; and to assess ...

5 The mtDNA haplogroups J and T share the same phylogenetic origin and a set of common uncoupling mitochondrial polymorphisms.12 These uncoupling polymorphisms confer different metabolic ...

Jin and his team conducted association analyses of 16 basal mitochondrial DNA haplogroups, genetic families tracing back to a common ancestor. They found that a specific variant group, named M7 ...

Haplogroup A2 was the most common, followed by B2 and D1, a trend similar to that reported in the Central Mesoamerican group. Based on the mitochondrial DNA sequence data, the six individuals were ...
