mTORC1, which is composed of mTOR, raptor, mLST8, and PRAS40, represents the central sensor of energy- and hormone-dependent metabolic regulation in metazoans (2,3). There is increasing evidence that the mammalian target of rapamycin (mTOR) pathway is involved in the pathogenic manifestations of diabetic nephropathy. mTOR phosphorylation is enhanced in the kidney cortex of diabetic rats, and treatment of rats with rather large doses of the mTOR inhibitor rapamycin blocks diabetes-induced glomerular hypertrophy and albuminuria (1–3). The mammalian target of rapamycin (mTOR), a serine/threonine kinase, lies downstream of the type I insulin‐like growth factor receptor‐phosphatidylinositol 3′ kinase‐Akt, and positively regulates phosphorylation of ribosomal p70 S6 kinase (S6K1) and eukaryotic initiation factor 4E (eIF4E) binding protein 1 (4E‐BP1).

Castedo M, Ferri KF, Kroemer G. PMID: 11840159 [Indexed for MEDLINE] Publication Types: News; Research Support, Non-U.S. Gov't; MeSH terms. Animals; Apoptosis*/drug effects; Autophagy; Cell Death; Immunophilins/physiology* Models, Biological; Protein Biosynthesis; Sirolimus/analogs & derivatives The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that has been increasingly recognized as key to the regulation of cell growth and proliferation. mTOR either directly or indirectly regulates translation initiation, actin organization, tRNA synthesis, ribosome biogenesis, and many other key cell maintenance functions, including protein degradation and transcription functions. The mammalian target of rapamycin (mTOR) has attracted substantial attention because of its involvement in a variety of diseases, such as cancer, cardiac hypertrophy, diabetes and obesity.

It has been reported that rapamycin, the inhibitor of mTOR and an immunosuppressant, blocks adipocyte differentiation, but the mechanism underlying this phenomenon remains unknown. Inducible gene expression appears to be an essential event that couples light to entrainment of the master mammalian circadian clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus.

INTRODUCTION. Calcineurin inhibitors (CNIs), initially cyclosporine, changed the standard of care with a substantial increase of graft survival at 1 year after kidney transplantation (KT). 1 Since the mid-1990s, a variety of immunosuppressive drugs were introduced, such as tacrolimus, mycophenolate mofetil (MMF), and mycophenolic acid (MPA) and the mammalian target of rapamycin inhibitors

The mammalian target of rapamycin (mTOR) is a protein kinase that regulates protein translation, cell growth, and apoptosis. Recently, there has been an enormous increase in our understanding on molecular mechanisms underlying the therapeutics of rapamycin in cancer.
