CELL BIOLOGY:
Enhanced: NO Says Yes to Mitochondria

Guy C. Brown

What boosts the number of mitochondria in our cells when, for example, we need to generate more heat or to work our muscles harder? In his Perspective, Brown discusses the answer to this question revealed in new work by Nisoli and colleagues. The gas nitric oxide (produced by endothelial nitric oxide synthase) activates a transcriptional coactivator that directs expression of genes, which induce mitochondrial biogenesis.
