Survivin属凋亡抑制蛋白家族新成员 ,具有抑制细胞凋亡和调节细胞分裂的双重功能 ;Survivin是肿瘤特异性凋亡抑制因子 ,高表达于多种肿瘤组织而在正常成人组织中未见表达。研究表明 ,Survivin在肿瘤的发生、发展过程中起关键作用 ,是估计肿瘤预后和复发的重要指标。Survivin还参与血管形成过程。近来 ,Survivin已成为肿瘤诊断、治疗的新靶点 Survivin is a new member of the apoptosis-inhibitory protein family, with the dual functions of inhibiting apoptosis and regulating cell division. Survivin is a tumor-specific inhibitor of apoptosis, which is highly expressed in many tumor tissues but not in normal adult tissues. Studies have shown that Survivin plays a key role in the development and progression of tumors and is an important indicator of tumor prognosis and recurrence. Survivin is also involved in the process of angiogenesis. Recently, Survivin has become a new target for diagnosis and treatment of tumors
