Systems Approaches to the mTOR Network

21/02/2017 - 14:00 - 15:00

Mammalian target of rapamycin (mTOR) kinase is a central controller of cellular growth and metabolism. mTOR is regulated by nutrients, growth factors, and stress, and acts in two structurally and functionally distinct multiprotein complexes, termed mTOR complex 1 (mTORC1) and mTORC2. Many tumors display mTOR dysregulation, making mTOR a prime target in cancer therapy. Our lab studies the control of metabolic homeostasis by mTOR by cell biology, biochemistry, proteomics, and systems modeling.

In my presentation, I will discuss our most recent advances to dissect amino acid signaling and stress inputs to the mTOR network by combined computational modeling and experimental strategies.
