Glucose acts as a double edged sword on longevity factor SIRT1

Feeding and fasting cycles exert control over metabolism and energy utilization. Aberrations are known to cause metabolic diseases, liver dysfunctions and accelerated aging. Expression and activity of the anti-aging factor ...

Cancer-like metabolism makes brain grow

The size of the human brain increased profoundly during evolution. A certain gene that is only found in humans triggers brain stem cells to form a larger pool of stem cells. As a consequence, more neurons can arise, which ...

Brain receptor regulates fat burning in cells

Scientists at the Gladstone Institutes have discovered an unusual regulator of body weight and the metabolic syndrome: a molecular mechanism more commonly associated with brain cells. Lowering levels of P75 neurotrophin receptor ...

Blocking pain receptors found to extend lifespan in mammals

Blocking a pain receptor in mice not only extends their lifespan, it also gives them a more youthful metabolism, including an improved insulin response that allows them to deal better with high blood sugar.

New study shows that even your fat cells need sleep

In a study that challenges the long-held notion that the primary function of sleep is to give rest to the brain, researchers have found that not getting enough shut-eye has a harmful impact on fat cells, reducing by 30 percent ...

Chemists determine one way tumors meet their growing need

Behaving something like ravenous monsters, tumors need plentiful supplies of cellular building blocks such as amino acids and nucleotides in order to keep growing at a rapid pace and survive under harsh conditions. How such ...
