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 study led by researchers at the Universitat Autònoma de Barcelona (UAB) and the Josep Carreras Leukemia Research Institute ...

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 ...

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 ...

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 breakthrough in treating an aggressive form of prostate cancer could boost survival rates, according to new research.

Researchers at Columbia University Irving Medical Center have identified a gene that drives the development of neuroendocrine ...

In 2001, researchers showed that a sirtuin protein—associated with the cellular stress response and metabolism—was essential for slowing aging in yeast. Now, researchers at Bar-Ilan University in ...
