Rapamycin regulates biochemical metabolites

Rapamycin regulates biochemical metabolites

The mammalian target of rapamycin (mTOR) kinase is a master regulator of protein synthesis that couples nutrient sensing to cell growth, and deregulation of this pathway is associated with tumorigenesis. p53, and its less investigated family member p73, have been shown to interact closely with mTOR pathways through the transcriptional regulation of different target genes. To investigate the met...

Rapamycin Regulates iTreg Function through CD39 and Runx1 Pathways

It has been shown that rapamycin is able to significantly increase the expression of FoxP3 and suppress activity in induced Treg (iTreg) cells in vivo and in vitro. CD39 is a newly determined Treg marker that relates to cell suppression. Runx1, a regulator of FoxP3, controls the expression of adenosine deaminase (ADA) gene, which is found recently in the downstream of CD39 pathway in trophoblas...

SIRT1 Negatively Regulates the Mammalian Target of Rapamycin

The IGF/mTOR pathway, which is modulated by nutrients, growth factors, energy status and cellular stress regulates aging in various organisms. SIRT1 is a NAD+ dependent deacetylase that is known to regulate caloric restriction mediated longevity in model organisms, and has also been linked to the insulin/IGF signaling pathway. Here we investigated the potential regulation of mTOR signaling by S...

Reconciliation of metabolites and biochemical reactions for metabolic networks

Genome-scale metabolic network reconstructions are now routinely used in the study of metabolic pathways, their evolution and design. The development of such reconstructions involves the integration of information on reactions and metabolites from the scientific literature as well as public databases and existing genome-scale metabolic models. The reconciliation of discrepancies between data fr...
