Measurement of the pathway's substrate, methylthioadenosine (mta), in two cohorts of sepsis patients demonstrated increased plasma mta in nonsurvivors plasma mta was correlated with levels of inflammatory cytokines, indicating that elevated mta marks a subset of patients with excessive inflammation.
Papers: ovarian cancer: which resulted in an accumulation of the metabolite 5'-methylthioadenosine (mta) in melanoma cells and in the extracellular environment. In addition, mta induced the secretion of basis fibroblast growth factor (bfgf) and mmp3 from fibroblasts and the upregulation of activator protein-1 (ap-1) activity in melanoma cells and fibroblasts. S-methyl-5'-thioadenosine phosphorylase is an enzyme that in humans is encoded by the mtap gene   this gene encodes an enzyme that plays a major role in polyamine metabolism and is important for the salvage of both adenine and methionine. S-adenosylmethionine (adomet) and 5′-methylthioadenosine (mta) exert a protective action on apoptosis induced by okadaic acid in primary rat hepatocytes but not in human transformed huh7 cells in the present work, we analyzed the role played by the jnk/activator protein (ap)-1 pathway in this differential effect. Recent evidence clearly demonstrates the central role of super-enhancers in a wide range of disease processes including autoimmune responses 5i depicts that.

Abstract retinyl esters are the major chemical forms of vitamin a stored in the liver, and can be delivered to peripheral tissues for conversion into biologically active forms t. Methylthioadenosine is a metabolite of the polyamine pathway that modulates methyltransferase activity, thereby influencing dna and protein methylation since methylthioadenosine produces neuroprotection in models of inflammation, ischemia and epilepsy, we set out to evaluate the role of methylthioadenosine in promoting remyelination, a process that will protect axons in demyelinating diseases. Methylthioadenosine (mta) is a by‐product during polyamine synthesis in transmethylation, same donates its methyl group to a large variety of acceptor molecules in reactions catalyzed by dozens of methyltransferase, the most abundant in the liver being glycine‐n‐methyltransferase (gnmt, reaction 2.
