溶血磷脂酰胆碱酰基转移酶1在肿瘤中作用的研究进展

Advances in the role of lysophosphatidyl-choline acyltransferase 1 in tumors

溶血磷脂酰胆碱酰基转移酶1作为磷脂胆碱代谢途径中的关键代谢酶,可通过脱酰基-再酰化来介导磷脂酰胆碱的合成,使细胞膜磷脂组成成分发生改变,导致细胞膜骨架发生重塑。溶血磷脂酰胆碱酰基转移酶1可通过加速肿瘤细胞膜磷脂成分的改变、或与表皮生长因子受体、细胞周期相关等肿瘤驱动基因相互作用影响肿瘤细胞的增殖、迁移和侵袭,以及肿瘤细胞的耐药性,促进肿瘤的发展。

Lysophosphatidylcholine acyltransferase 1(LPCAT1),a key metabolic enzyme in the phosphatidyl-choline metabolism pathway,mediates phosphatidylcholine synthesis through deacylation-reacylation,which leads to alterations in the phospholipids composition of cell membranes and the remodelling of the cellular cytoskeleton.Lysophosphatidylcholine acyltransferase 1 has been shown to be highly expressed in gastric,breast and colorectal cancer,and can accelerate the alteration of the phospholipids composition of tumor cell membranes or interact with tumor driver genes,such as epidermal growth factor receptor and cell cycle-related genes.It might promote tumor development by affecting tumor cell proliferation,migration,invasion and resistance to chemotherapy.
