γ-谷氨酰转肽酶(γ-GTP)系哺乳动物脏器的上皮细胞膜结合酶。在体内参与解毒及谷胱甘肽的分解。作为α-甲胎蛋白及肝癌的主要标志受到重视。最近,作者发现肝癌γ-GTP糖链与正常的不同。据此开发了肝癌诊断的新方法。其糖链结构变化不仅在肝癌中出现,同样其他脏器癌变亦有此现象。可 Gamma-glutamyl transpeptidase (γ-GTP) is an epithelial cell membrane-bound enzyme in mammalian organs. In the body involved in detoxification and glutathione decomposition. As a-a-fetoprotein and liver cancer as the main mark of attention. Recently, the authors found that the liver cancer Gamma-GTP sugar chain and the normal difference. Accordingly developed a new method of liver cancer diagnosis. The sugar chain structure changes not only in liver cancer, the same cancer of other organs also have this phenomenon. can
