涉及叶酸和甲硫氨酸循环的一碳代谢整合来自氨基酸(包括丝氨酸和甘氨酸)的碳单元,并产生多种输出,如脂质、核苷酸和蛋白质的生物合成,氧化还原状态的维持,以及甲基化反应的底物。长期以来被认为是一个“管家”的过程,这条途径最近已被证明具有额外的复杂性。最近的遗传和功能证据也表明,该途径的过度活化是肿瘤发生的可能驱动因素,并与细胞表观遗传状态建立了联系。鉴于临床上有大量针对一碳代谢的药物,这些新发现可能为转化为精确的癌症药物提供机会。
One carbon metabolism involving the folate and methionine cycle integrates carbon units from amino acids, including serine and glycine, and generates diverse outputs, such as the biosynthesis of lipids, nucleotides and proteins, the maintenance of redox status, and the substrates for methylation reactions. Long considered a ‘housekeeping’ process, this pathway has been recently shown to have additional complexity. Recent genetic and functional evidence also suggests that hyperactivation of this pathway is a possible driver of oncogenesis and establishes links to cellular epigenetic status. Given the wealth of clinically available agents that target one carbon metabolism, these new findings could present opportunities for translation into precision cancer medicine.
