    Am J Physiol Endocrinol Metab 284:E322-30. 2003
    ..We suggest that, in adipose cells, a predominant part of leptin mRNA is compartmentalized on the endoplasmic reticulum, and leucine activates translation of these messages via the mTOR/4E-BP/PHAS-1-mediated signaling pathway...

    Boston University School of Medicine, Massachusetts 02118, USA
    Mol Cell Biol 26:63-76. 2006
    ..Thus, diabetes-related hyperglycemia hyperactivates the mTOR pathway and may lead to insulin resistance due to suppression of IRS-1-dependent PI3-kinase/Akt signaling...

    Molecular Oncology Research Institute, Tufts New England Medical Center, Boston, Massachusetts 02111, USA
    J Biol Chem 282:18069-82. 2007
    ..These data define a novel pathway that cooperates with other adaptive mechanisms to formulate the cellular response to energy depletion...
