摘要 浸润和转移是恶性肿瘤的重要特征 ,也是引起肿瘤病例死亡的主要原因。KAIl CD82属四次跨膜超家族的成员 ,其结构为细胞膜糖蛋白。目前研究多种肿瘤中均证实了转移的肿瘤往往伴随KAIl CD82基因的表达下降或缺失 ,最新研究发现TM 4SF家族部分成员可与整合素形成复合体 ,从而调节整合素的黏附功能 ,并影响整合素介导的细胞转移。 Invasion and metastasis are two important characteristics of malignant tumor, and they are main death causes of the patients with cancer. KAIl/CD82 is a member of transmembrane 4 superfamily(TM4SF), and its structure is a glycoprotein on the cellular membrane. From recent studies on different kinds of neoplasms, it is confirmed that the metastasized tumor is often accompanied by decrease or absence in expression of KAIl/CD82 gene. Recent study showed that parts of TM4SF and integrin can form a complex, which can regulate adhesive function of integrin and influence integrin mediated cell metastasis.
