生化/生理作用

S-(5′-腺苷)-L-高半胱氨酸(AdoHcy/SAH)是细胞内高半胱氨酸应激的一个组成部分。AdoHcy是参与表观遗传学的DNA甲基转移酶(S-腺苷-L-甲硫氨酸(AdoMet)依赖的甲基转移酶)的竞争性抑制剂(与AdoMet竞争)。因此,AdoHcy可用于各种高同型半胱氨酸状态的表观遗传学研究。AdoHcy是被S-腺苷高半胱氨酸水解酶(AHCY)代谢的。AdoHcy是S-腺苷甲硫氨酸(SAM)相关的酶促转甲基反应的产物。通过其切割产生腺苷和L-高半胱氨酸,将其重新转化为SAM——它是噻亭高半胱氨酸S-甲基转移酶的底物。血浆中SAM和SAH的浓度变化可作为细胞甲基化潜能和代谢变化的预测因子。甲基化能力代表特定的遗传多态性和/或营养缺乏。甲基化在表观遗传学、重编程和癌症中具有重要作用。

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

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

文章

Epigenetic modifications are thought to occur through two key interconnected processes—DNA methylation and the covalent modification of histones.
