摘要
葡萄糖转运蛋白(GLUT)是分布在细胞膜的跨膜糖蛋白,介导葡萄糖在细胞膜两侧的转运。不同的GLUT在组织中的分布、功能、调控机制等方面均存在差异。研究发现,肿瘤细胞表面有异常的GLUT的表达,尤其是GLUT1。GLUT1的高表达可以作为细胞恶性转化的标志,并与肿瘤细胞的增殖、侵袭能力、转移密切相关,可能对肿瘤的早期诊断及判断预后提供新的依据。
GLUT is a sugar-protein in cell membrane,which responses for the transport of sugar in the cell membrane. The distribution, function, regulation of different kinds of GLUT are different in tissues. GLUT is highly expressed in tumor cells, especially GLUT1. The high expression is a marker of the cell malignant transformation and relates with the tumor cell growing,invasion ability and metastasis. It may provide a new proof to the early diagnose and may be a useful predictor of poor prognosis.
