Regulation of the Target of Rapamycin Signaling Pathway in Saccharomyces cerevisiae
<p>An integrative, biochemical, genetic, and molecular biology approach utilizing gene manipulation, gene knock outs, plasmid based protein expression, and <em>in vivo</em> protein localization of fluorescence tagged proteins was employed to determine the function of an essential protein, Lst8, in …

Regulation of Skeletal Muscle Differentiation by a Rapamycin -Sensitive Signaling Pathway
… is completely dispensable. Both the FKBP 12-rapamycin binding domain (FRB) and the kinase domain are necessary for mTOR's myogenic function despite kinase activity being dispensable. These observations provide structural insights into the regulatory mechanisms of mTOR, possibly involving …

Identification of a new tumor suppressor pathway modulating rapamycin sensitivity in colorectal cancer
… Small molecule drugs targeting mTOR, such as rapamycin, have been shown to be promising for cancer therapy. However, the clinical responses to the rapamycin as mTOR-targeted therapy are frequently confounded by acquired resistance. In colon cancer, loss of PPP2R2B leads to induction of …

The Role of the Mammalian Target of Rapamycin (mTOR) in Cytotoxic T Lymphocytes
The serine-threonine kinase mammalian target of rapamycin (mTOR) is an important integrator of nutrient, cytokine and growth factor sensing in T cells and controls transcriptional programs that determine CD8+ cytotoxic T cell fate and trafficking. mTORC1 is inhibited by the drug rapamycin which is …

Investigation of the Function and Regulatory Mechanisms of the Mammalian Target of Rapamycin
Unexpectedly, mTOR has been found to shuttle between the nucleus and the cytoplasm, and this shuttling is required for its cytoplasmic signaling. I have further investigated the regulation and function of mTOR cytoplasmic-nuclear shuttling. A systematic screen of mTOR revealed a rev-like NES …

The independent and combined effects of rapamycin and metformin on naturally occurring osteoarthritis
… Inhibiting the mechanistic target of rapamycin (mTOR) and stimulating AMP-activated protein kinase (AMPK) has extended lifespan and protected against post-traumatic (secondary) OA in mice. However, it remains unknown if manipulation of these pathways can protect against naturally …

Divergent Roles of PI3K and Akt in Rapamycin-induced Cardioprotection against Ischemia-Reperfusion Injury
… by ischemia-reperfusion injury (I-R injury). Rapamycin is one such drug that has been shown to protect the heart against ischemia-induced cellular injury. Rapamycin(sirolimus) inhibits protein synthesis through inhibition of the mammalian target ofrapamycin (mTOR). This property of rapamycin …

The role of mammalian target of rapamycin complex 1 in hepatic physiology and disease
… We have found that inhibition of mTORC 1 with rapamycin treatment suppressed whole-body postnatal growth similar to reduced caloric intake. We found that while feeding activated mTORC 1 in almost every tissue, there was variability in the upstream activating stimuli. The role of mTORCl in organ …

Role of PRAS40 in mammalian target of rapamycin (mTOR) modulation in cancer and insulin resistance
<p>Dysregulation of PI3K-AKT-mTOR pathway has been reported in various pathologies, such as cancer and insulin resistance. The proline-rich AKT substrate of 40-kDa (PRAS40), also known as AKT substrate 1 (AKT1S1), lies at the crossroads of these cascades and inhibits the activity of the mTOR …

The effect of mTOR inhibitor rapamycin on a dietary Drosophila melanogaster model of calcium oxalate nephrolithiasis
… The mechanistic (mammalian) target of rapamycin (mTOR) activity is characteristic of metabolic syndrome. When nutrients are abundant, mTOR is active. Conversely, fasting inhibits mTOR. Metabolic syndrome is correlated with an increased risk of self-reported or imaging findings of …

Environmental Signaling through the Target of Rapamycin Complex 1 (TORC1) and the Regulation of Epigenetic Mechanisms
… signaling complexes, such as the target of rapamycin complex 1 (TORC1), to downstream chromatin modifying enzymes. These enzymes impact the gene regulatory process through altered histone post-translation modifications, changes in chromatin structure, and docking of chromatin regulatory …

Identification of interacting partners of mammalian target of rapamycin complex 1 (mTORC1) assembly in human lymphocytes
The mammalian target of rapamycin (mTOR) is an intracellular protein kinase that plays a key role in the control of cell growth, differentiation, cell survival, and cell proliferation. In humans, mTOR deregulation is implicated in parasitic, fungal, bacterial and viral infections, immune disorders, …

The Effect of Rapamycin Paired with Traumatic Memory Activation on Cognitive Performance in Veterans Diagnosed with PTSD
… symptoms. Animal studies have shown that rapamycin, a protein synthesis inhibitor that targets the protein kinase mTOR, can prevent the reconsolidation of a reactivated fear memory, thereby reducing its emotional strength at a neurochemical level. The aim of the current study was to …

Investigation into the effects and mechanisms of rapamycin treatment in two mouse models of Complex I-deficient neurological pathology
… that inhibition of the mechanistic target of rapamycin (mTOR) signaling pathway is effective at reducing markers of pathology in experimental models of age-related and developmental neurological diseases. These include, but are not limited to, models for Alzheimer's disease, Parkinson's …
