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 ...

A study has described a mechanism that plays a key role in the evolution of Alzheimer’s disease. According to the paper, the activation of the protein Sirtuin 1 in a murine model with familial ...

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 potentially promising approach to treating Alzheimer’s disease has been developed by researchers studying sirtuin, a protein thought capable of extending lifespan in laboratory animals. Using mice ...

Study reveals that Sirtuin 7 regulates the functions of brown adipose tissue, thereby playing a critical role in overall energy regulation. Mammals convert the energy stored in adipose (fat) tissue ...

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 ...
