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.

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 ...

Mammals convert the energy stored in adipose (fat) tissue into heat via a process known as thermogenesis. This process is regulated by a family of signaling proteins called sirtuins. A recent study by ...

Sirtuins, which are a highly conserved family of NAD+-dependent deacetylases, have been shown to be involved in a wide range of physiological and pathological processes, including aging, energy ...

If your New Year resolution has been to lose weight and eat healthy, here is some good news – dark chocolate and red wine may actually help you achieve your goal. These two food items belong to the ...

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 ...
