摘要
机体内有多种细胞可以分泌一种磷酸化蛋白———骨桥蛋白 (OPN) ,依靠整合素的辅助 ,OPN在不同的生理和病理机制中起着重要的作用。很多种肿瘤组织都可以表达OPN。近来的一些研究表明 ,肿瘤细胞表达的OPN与肿瘤的侵袭、转移过程关系密切。
Osteopontin (OPN) is a multifunctional phosphoprotein secreted by various cells.OPN serves in both cell attachment and cell signaling by interacting with integrins in various pathological conditions.OPN expression has been demonstrated in a variety of human carcinomas.The recent studies showed that OPN expressed by tumor cells was associated with the motile and invasive behaviors of tumor cells,suggesting that OPN might contribute to invasion and metastasis of tumors.
