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 ...

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 ...

'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 ...
