Historical genomes reveal recent changes in genetic health of eastern gorillas

Historical genomes reveal recent changes in genetic health of eastern gorillas

Press releases   •   Dec 27, 2018 16:00 GMT

The critically endangered Grauer’s gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. Results are published in Current Biology.

New knowledge about retrovirus-host coevolution

Press releases   •   Oct 08, 2018 20:00 BST

Retroviruses have colonised vertebrate hosts for millions of years by inserting their genes into host genomes, enabling their inheritance through generations as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new knowledge about the long-term associations of retroviruses and their hosts by studying ERV variation and segregation in wild and domestic rabbits.

Tea consumption leads to epigenetic changes in women

Press releases   •   May 31, 2017 07:10 BST

Epigenetic changes are chemical modifications that turn our genes off or on. In a new study from Uppsala University, researchers show that tea consumption in women leads to epigenetic changes in genes that are known to interact with cancer and estrogen metabolism. The results are published in the journal Human Molecular Genetics.

Genetic data show mainly men migrated from the Pontic steppe to Europe 5,000 years ago

A new study, looking at the sex-specifically inherited X chromosome of prehistoric human remains, shows that hardly any women took part in the extensive migration from the Pontic-Caspian Steppe approximately 5,000 years ago. The great migration that brought farming practices to Europe 4,000 years earlier, on the other hand, consisted of both women and men.
