Regulation of mitochondrial biogenesis in eukaryotic cells.
Mitochondria amount within a cell is modulated in response to energy demand. This involves a tight regulation of mitochondrial biogenesis and the coordinated expression of hundreds of genes, both at the nuclear and at the mitochondrial level. This review will focus on two aspects of mitochondrial biogenesis regulation: (i) In mammalian cells, physiological effectors, and the regulatory proteins that control the expression of the respiratory apparatus, will be considered, and different kinds of tissue will be addressed. (ii) In yeast, the regulation of mitochondrial biogenesis in response to growth conditions as well as the signaling pathway involved will be considered.
