Tumor suppressive properties of maspin and its expression levels in tumors / 肿瘤研究与临床

ABSTRACT

Maspin (mammary serine protease inhibitor) is a kind of serpin.Many studies have characterized it as a tumor suppressor based on its ability to inhibit tumor angiogenesis,increase adhesion between tumor cells and ECM,inhibit tumor cell invasion and distant metastasis and promote apoptosis.In recent years,some studies have found maspin expresses high in some cancers,such as in mammary cancer and prostate cancer,while in some other cancers,such as in pancreatic cancer,maspin expression level shows high.The expression levels and biological functions of maspin in different organs still need further study.
