Example sentences for: mtor
How can you use “mtor” in a sentence? Here are some example sentences to help you improve your vocabulary:
Rapamycin inhibits activation of p70 S6 kinase, a downstream effector in the PI 3-kinase signaling pathway [ 13 ] . Rapamycin forms a complex with FK506-binding protein 12 and this complex blocks the kinase activity of mTOR (mammalian target of rapamycin), a kinase upstream of p70 S6 kinase [ 20 ] . The IC 50 for p70 S6 kinase inhibition by rapamycin is ~0.
Clinical trials using the rapamycin analog CCI-779 show promise for this strategy [ 22 ] . Rapamycin and its synthetic analogs block mTOR kinase activity leading to dephosphorylation of 4EBP and other mTOR substrates.
ANOVA = analysis of variance; Erk= extracellular signal-regulated kinase; IC 50 = half-maximal inhibition; IRS = insulin receptor substrate; LDH = lactate dehydrogenase; MAPK = mitogen-activated protein kinase; MEK = MAPK/extracellular signal-regulated kinase kinase; mTOR = mammalian target of rapamycin; PBS = phosphate-buffered saline; PI 3-kinase = phosphatidylinositol 3-kinase; RDS = respiratory distress syndrome; SD = standard deviation of the mean; SE = standard error of the mean; SP = surfactant protein; TPA = 12-
Cumulatively, however, these observations do suggest a mechanism whereby HIV-1 expression in renal epithelium may induce cyclin D 1 : activation of Src-family kinases by Nef would be expected to up-regulate cyclin D 1 gene expression and promote the synthesis and stabilization of cyclin D 1 protein via Src-Ras-MAPK and Src-PI3K-mTOR signal transduction pathways, respectively [ 32 33 34 ] . Interestingly, our unpublished in vitro observations and published data showing marked expression of basic fibroblast growth factor in the interstitium of HIVAN kidneys [ 35 ] suggest that soluble mitogens may be important cofactors with HIV-1 expression to induce cyclin D 1 . Thus, interrupting HIV-1 gene expression should down-regulate cyclin D 1 and correct the phenotypic abnormalities in infected podocytes.
One such candidate is the rapamycin analog CCI779, which has been suggested to inhibit the AKT signaling pathway, probably through inhibition of mTOR (target of rapamycin), a potential target of AKT [reviewed in ref.
