Sirtuin genes and the proteins they encode were already linked to longevity in yeast. Now, a previously overlooked member of the family has excited researchers who study aging At last, a member of the ...

Jellyfish, sea sponges, amoebas and other animals on the early branches of the tree of life defy conventional aging. A new study reveals diversity of proteins called sirtuins in these animals compared ...

Scientists from Johns Hopkins and the University of Wisconsin have discovered that a protein called Sir2, which is found in nearly all living cells, has a new function that might help explain how ...

A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 23, entitled, "Sirtuin 6 activation rescues the ...

A new study has identified a protein found in fat cells that may play a major role in how fat is produced and stored, offering a new target for treatments to prevent obesity and reduce the risk for ...

A formerly underappreciated member of the sirtuin family of proteins may hold the key to youthfulness and is the first sirtuin shown to specifically govern the activity of genes, scientists report.

Animals on the early branches of the tree of life, such as jellyfish and sea sponges, defy the usual conventions of aging. Some show abilities to regenerate damaged or missing tissues, halt or reverse ...
