磷酸甘油酸变位酶1在肿瘤发生及发展中的作用

Role of phosphoglycerate mutase 1 in the occurence and development of tumor

磷酸甘油酸变位酶1(phosphoglycerate mutase 1,PGAM1)作为糖酵解通路的重要酶之一,在多种肿瘤组织中高表达,并且与肿瘤患者预后呈负相关。PGAM1催化糖酵解通路中3-磷酸甘油酸(3-phosphoglycerate,3-PG)转化生成2-磷酸甘油酸(2-phosphoglycerate,2-PG),促进葡萄糖代谢和能量生成。PGAM1通过调节3-PG与2-PG的转化平衡来影响其他代谢通路,参与细胞内生物大分子合成和维持氧化还原稳态,促进肿瘤细胞增殖及转移。PGAM1作为潜在的抗肿瘤靶标,其抑制剂的研发也成为抗肿瘤药物研究热点之一。该文对PGAM1结构、调控、在肿瘤发生及发展中的作用以及PGAM1抑制剂的最新研究进展作一综述。

Phosphoglycerate mutase 1（PGAM1） as one of the most important enzymes for glycolysis pathway, is highly expressed in multiple tumor tissues and negatively correlated with the prognosis of cancer patients. PGAM1 catalyzes the conversion of 3-phosphoglycerate（3-PG） to 2-phosphoglycerate（2-PG） in glycolysis pathway, then promoting anabolic pathways, energy generation, and maintaining redox balance during cancer cell proliferation and metastasis. The small molecule PGAM1 inhibitors have emerged as a promising strategy for anti-tumor therapy. In this review, the significance of PGAM1 in tumor was reviewed and the research progress of PGAM1 inhibitors was also introduced.
