SAH is suitable for use:
- to investigate whether AdoHcy competes with AdoMet in the down-regulation of reporter activity of LUC reporter gene
- as a reagent to study the abundance patterns of SAH and its correlation with vertebrate metamorphosis
- in the optimization of the protein (lysine K) methyltransferase SET7/9 activity assay
- in the fluorescence polarization (FP) assay during dengue virus methyltransferase activity measurement
- as a standard for the measurement of SAH from blood samples by high performance liquid chromatography (HPLC) with fluorimetric detection method
생화학적/생리학적 작용
S-(5′-Adenosyl)-L-homocysteine (AdoHcy/SAH) is a component of intracellular homocysteine stress. AdoHcy is a competitive inhibitor (versus AdoMet) of DNA methyltransferases (S-adenosyl-L-methionine (AdoMet)-dependent methyltransferases) involved in epigenetics. Consequently, AdoHcy is used in a variety of studies on epigenetics in hyperhomocysteinemic states. AdoHcy is metabolized by S-adenosylhomocysteine hydrolase (AHCY). AdoHcy is the product of enzymatic transmethylation reactions involving S-Adenosylmethionine (SAM). It is reconverted to SAM by its cleavage into adenosine and L-homocysteine, a substrate of thetin-homocysteine S-methyltransferase. The concentration alterations of SAM and SAH in plasma serve as predictors of cellular methylation potential and metabolic alterations. Methylation capacity indicates specific genetic polymorphisms and/or nutritional deficiencies. Methylation is important in epigenetics, reprogramming, and cancer.

Elevated plasma homocysteine is associated with an increased risk of intravascular thrombosis. Platelet aggregation and thrombosis are inhibited by prostacyclin produced by the vascular endothelium. Our aim was to investigate whether homocysteine and related metabolites inhibit endothelial prostacyclin production. We

S-Adenosyl-Lmethionine (SAM) is an important molecule in normal cell function and survival. SAM is utilized by three key metabolic pathways: transmethylation; transsulfuration; and polyamine synthesis. In transmethylation reactions, the methyl group of SAM is donated to a large variety of

Chemical inhibition of proteins involved in chromatin-mediated signaling is an emerging strategy to control chromatin compaction with the aim to reprogram expression networks to alter disease states. Protein methyltransferases constitute one of the protein families that participate in epigenetic control
