mTOR controls mitochondrial oxidative function through a YY1–PGC-1α transcriptional complex

mTOR controls mitochondrial oxidative function through a YY1–PGC-1α transcriptional complex The nutrient sensor molecule mTOR (mammalian target of rapamycin) is a kinase involved in the regulation of cell growth and proliferation. Its close links to the cell's energetics suggest that it might interact with the mitochondria, and a computational genomics study now confirms that it does. mTOR balances energy metabolism via transcriptional control of mitochondrial gene expression and oxidative function, with the transcriptional regulators PGC-1a and YY1 as mediators. This pathway opens new possibilities for therapeutic interventions in metabolic diseases in which mitochondrial activity is compromised. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

The nutrient sensor molecule mTOR (mammalian target of rapamycin) is a kinase involved in the regulation of cell growth and proliferation. Its close links to the cell's energetics suggest that it might interact with the mitochondria, and a computational genomics study now confirms that it does. mTOR balances energy metabolism via transcriptional control of mitochondrial gene expression and oxidative function, with the transcriptional regulators PGC-1a and YY1 as mediators. This pathway opens new possibilities for therapeutic interventions in metabolic diseases in which mitochondrial activity is compromised.
