Deregulation of the phosphoinositide 3-kinase-Akt pathway is a major contributor to oncogenesis and resistance to cancer therapy. Recent work has shown mammalian target of rapamycin (mTOR) to be a major target downstream of Akt that contributes to both transformation and therapeutic resistance. Although inhibitors of Akt are not yet clinically available, rapamycin, a mTOR-specific inhibitor, ha...
BACKGROUND and OBJECTIVES: mTOR (a serine/threonine protein kinase) is a major repressor of autophagy, a cell survival mechanism. The specific in vivo mechanism of mTOR signalling in OA pathophysiology is not fully characterised. We determined the expression of mTOR and known autophagy genes in human OA cartilage as well as mouse and dog models of experimental OA. We created cartilage-specific ...
Sepsis and lipopolysaccharide (LPS) may decrease skeletal muscle protein synthesis by impairing mTOR (mammalian target of rapamycin) activity. The role of mTOR in regulating muscle protein synthesis was assessed in wild-type (WT) and mTOR heterozygous (+/-) mice under basal conditions and in response to LPS and/or leucine stimulation. No difference in body weight of mTOR(+/-) mice was observed ...

Macrophages can change their phenotypes according to the changes in microenvironment, and thus have various functions, that is, macrophages polarization. Macrophage phenotype is associated with progression of atherosclerotic plaques. Studies shown a large accumulation p62 protein Whether affects level macrophage polarization inflammation its mechanism not clear. The levels treated ox-LDL were d...
The mammalian target of rapamycin (mTOR), a serine/threonine protein kinase, acts as a "master switch" for cellular anabolic and catabolic processes, regulating the rate of cell growth and proliferation. Dysregulation of the mTOR signaling pathway occurs frequently in a variety of human tumors, and thus, mTOR has emerged as an important target for the design of anticancer agents. mTOR is found ...
In response to growth factors, mTOR (mammalian target of rapamycin) has been identified as a central component of the signalling pathways that control the translational machinery and cell growth. Signalling through mTOR has also been shown to be necessary for the mechanical load-induced growth of cardiac and skeletal muscles. Although the mechanisms involved for mechanically induced activation ...
We investigate the roles of mTor signaling in the formation of Müller glia-derived progenitor cells (MGPCs) in the chick retina. During embryonic development, pS6 (a readout of active mTor signaling) is present in early-stage retinal progenitors, differentiating amacrine and ganglion cells, and late-stage progenitors or maturing Müller glia. By contrast, pS6 is present at low levels in a few sc...
REDD2 is enriched in skeletal muscle and inhibits mTOR signaling in response to leucine and stretch.
The protein kinase mammalian target of rapamycin (mTOR) is well established as a key regulator of skeletal muscle size. In this study, we determined that the stress responsive gene REDD2 (regulated in development and DNA damage responses 2) is a negative regulator of mTOR signaling and is expressed predominantly in skeletal muscle. Overexpression of REDD2 in muscle cells significantly inhibited...
BACKGROUND Neuropathic pain is a type of chronic pain that results from dysfunctions of the somatosensory nerve system. This study was aimed to investigate the effect of mTOR/VEGF signaling pathway on neuropathic pain and the regulation mechanisms of miR-183 on AMPA Receptors through mTOR/VEGF signaling pathway. METHODS Chronic compress injury (CCI) model was constructed in the current study,...
