摘要: 肝癌是全球癌症负担的主要来源,而肝癌中最主要的组织学类型为肝细胞癌(Hepatocellular carcinoma,HCC)。因此,阐明HCC发生发展、复发机制以及寻找新的治疗靶点成为HCC研究的重要方向。近年来越来越多的学者对糖基磷脂酰肌醇(GPI)锚定蛋白合成过程进行研究,发现参与GPI锚定蛋白合成的多个亚基的表达异常不仅参与了人类疾病的发展,也参与了人类多种肿瘤的发生发展,糖基磷脂酰肌醇转酰胺酶(Glycosylphosphatidylinositol transamidase,GPI-T)作为蛋白质转移到GPI锚的关键酶,由五个亚基组成,其中PIGU于2004年被首次证明参与了膀胱癌的发生发展,随后它的五个亚基逐渐被证实参与了HCC的发生发展。本文就GPI-T的五个亚基参与HCC发生及发展的机制进行了阐述。

Abstract: Liver cancer is the main source of the global cancer burden,and the most important histological type of liver cancer is hepatocellular carcinoma(HCC).Therefore,elucidating the mechanism of HCC occurrence,development,recurrence and finding new therapeutic targets have become an important direction of HCC research.In recent years,more and more scholars have studied the synthesis of glucosyl phosphatidylinositol(GPI)anchored proteins,and found that the abnormal expression of multiple subunits involved in the synthesis of GPI-anchored proteins is not only involved in the development of human disease,but also participated in the occurrence and development of a variety of human tumors.Glycosylphosphatidylinositol transamidase(GPI-T),consisting of five subunits,acts as a key enzyme for protein transfer to GPI anchors.PIGU was introduced in 2004.It was proved to be involved in the occurrence and development of bladder cancer for the first time,and then its five subunits were gradually confirmed to be involved in the occurrence and development of HCC.In this paper,five subunits of GPIT involved in the pathogenesis and development of HCC were reviewed.

Key words: Glycosylphosphatidylinositol transamidase, Hepatocellular carcinoma, Phosphatidylinositol glycan anchoring biosynthesis class
