When DNA that turns up in the wrong place in mammalian cells, the innate immune system reacts by secreting interferons. The structure and mode of action of the enzyme that mediates this response have now been elucidated. In animal cells, DNA molecules are normally restricted to the cell nucleus and the mitochondria. When DNA appears outside these organelles — in the so-called cytosol - it most probably originates from a bacterial pathogen or a DNA virus. This is why cytosolic DNA...

Cell's power generator depends on long-sought protein Mitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound. Because calcium levels link to many essential biological processes"”not to mention conditions such as neurological disease and diabetes"”scientists have been working for half a...

Excess amounts of a naturally fluorescent molecule found in all living cells could serve as a natural biomarker for cancer, according to bioengineers.NADH, or nicotinamide adenine dinucleotide, is a key coenzyme -- a non-protein molecule necessary for the functioning of an enzyme -- found mostly in the inner membrane of a cell's power plant, or mitochondria. It fuels a series of biochemical reactions that involve various enzymes to produce ATP, the major energy source in cells. In the event...
