摘　　要：恶性肿瘤严重威胁着人类健康,是全球人类死亡的主要原因之一。为了进一步提高对于恶性肿瘤的治疗效果,延长患者生存时间,明确恶性肿瘤的发病机制以及寻找新的诊断和治疗靶点变得尤为重要。研究发现,恶性肿瘤的发生发展是肿瘤细胞与肿瘤微环境(tumor microenvironment,TME)相互作用的结果。多能蛋白聚糖(versican)是一种硫酸软骨素蛋白聚糖,属于外源凝集素蛋白聚糖家族,由VCAN基因编码,是细胞外基质的主要成分,在胚胎发育和炎症反应过程中均发挥重要作用。作为TME的重要组成部分,versican在肾细胞癌、肝细胞癌、胃癌等多种肿瘤组织中异常表达,且与患者的临床病理特征及预后密切相关,是肿瘤早期诊断和预后评估的潜在生物标志物。进一步的研究显示,versican可通过促进肿瘤细胞增殖、侵袭和转移,抑制肿瘤细胞凋亡,促进肿瘤血管生成和抑制抗肿瘤免疫反应等多种方式促进肿瘤的发展。该文就versican在恶性肿瘤中的表达及生物学作用的研究现状进行综述,旨在为肿瘤的后续研究及临床诊治提供参考依据。Malignant tumors pose a serious threat to human health and are one of the main causes of human death worldwide.In order to further improve the therapeutic outcomes of malignant tumors and prolong patients'survival time,clarifying the pathogenesis of malignant tumors and searching for new diagnostic and therapeutic targets become particularly important.It has been found that the occurrence and development of malignant tumors are the results of the interaction between tumor cells and the tumor microenvironment(TME).Versican,encoded by the VCAN gene,is a type of chondroitin sulfate proteoglycan belonging to the exogenous lectin proteoglycan family.It is a major component of the extracellular matrix and plays an important role in embryonic development and inflammatory responses.As an important component of TME,versican is abnormally expressed in various tumor tissues such as renal cell carcinoma,hepatocellular carcinoma,and gastric cancer,and is closely related to the clinical pathological characteristics and prognosis of the patients.It is a potential biomarker for early diagnosis and prognostic evaluation of tumors.Further researches have shown that versican can promote tumor development in a number of ways,such as promoting tumor cell proliferation,invasion and metastasis,inhibiting tumor cell apoptosis,promoting tumor angiogenesis,and inhibiting anti-tumor immune responses.This article reviews the current research status of the expression and biological effects of versican in malignant tumors,aiming to provide reference for subsequent research,clinical diagnosis and treatment of tumors.
