Cellular growth signals stimulate anabolic processes. The mechanistic target of rapamycin complex 1 (mTORC1) is a protein kinase that senses growth signals to regulate anabolic growth and proliferation. Activation of mTORC1 led to the acute stimulation of metabolic flux through the de novo pyrimidine synthesis pathway. mTORC1 signaling posttranslationally(More)
The mammalian target of rapamycin complex 1 (mTORC1) has the ability to sense a variety of essential nutrients and respond by altering cellular metabolic processes. Hence, this protein kinase complex is poised to influence adaptive changes to nutrient fluctuations toward the maintenance of whole-body metabolic homeostasis. Defects in mTORC1 regulation,(More)
mTOR [mammalian (or mechanistic) target of rapamycin] is a protein kinase that, as part of mTORC1 (mTOR complex 1), acts as a critical molecular link between growth signals and the processes underlying cell growth. Although there has been intense interest in the upstream mechanisms regulating mTORC1, the full repertoire of downstream molecular events(More)
