晚期糖基化终产物受体异常表达对肿瘤发生和侵袭转移的影响

Role of abnormal expression of receptor for advanced glycosylation end products in carcinogenesis,tumor invasion,and metastasis

以往人们将晚期糖基化终产物受体(receptor for advanced glycosylation end products,RAGE)的研究重点放在糖尿病血管病变中。近年来的临床研究发现,RAGE在人肝癌、胃癌、胰腺癌和前列腺癌等多种肿瘤组织中均高表达,而在横纹肌肉瘤和肺癌组织中低表达。RAGE的异常表达与肿瘤的发生、血管生成和侵袭转移等恶性化程度密切相关。本文对不同肿瘤组织中RAGE的异常表达及其与肿瘤发生、发展的相关性进行简要综述。

Receptor for advanced glycosylation end products （RAGE） has long been a focus in studies of diabetic vascular diseases. Recently, clinical evidence has shown that the expression level of RAGE is high in liver, stomach, pancreas and prostate cancer tissues whereas the expression level of RAGE is lower in chondrosarcoma and lung cancer tissues. The abnormal expression of RAGE is closely associated with tumorgenesis, angiogenesis, tumor invasion and metastasis. This review summarizes the abnormal expression of RAGE in different tumors and its role in carcinogenesis and development of tumor.
