Do our mitochondria run at 50 degrees C?

Our body temperature is held at a fairly steady 37.5°C, and the assumption has always been that most of our physiological processes take place at this temperature. The heat needed to maintain this temperature in the face ...

When less is more: How mitochondrial signals extend lifespan

In making your pro-longevity resolutions, like drinking more red wine and maintaining a vibrant social network, here's one you likely forgot: dialing down your mitochondria. It turns out that slowing the engines of these ...

'Anti-Atkins' low protein diet extends lifespan in flies

Flies fed an "anti-Atkins" low protein diet live longer because their mitochondria function better. The research, done at the Buck Institute for Age Research, shows that the molecular mechanisms responsible for the lifespan ...

Researchers discover mitochondria-to-nucleus messenger protein

Researchers have identified a protein, G-Protein Pathway Suppressor 2 (GPS2), that moves from a cell's mitochondria to its nucleus in response to stress and during the differentiation of fat cells. While proteins with similar ...

Tampering with cellular fats holds great promise

Today, much of the biology underlying the cellular composition of lipids is a black box to scientists. Even though lipids are a major group of biomolecules, they are difficult to study because their synthesis is regulated ...

Newly discovered cytoskeleton helps cancer cells survive

Researchers at Lund University in Sweden have discovered a cytoskeleton which provides the structure for mitochondria, the cell's energy producers. The skeleton is necessary for the function of the mitochondria, but the researchers ...
