现代肿瘤研究发现细胞增殖和细胞凋亡调控失常是普遍现象 ,细胞凋亡受抑使得肿瘤细胞生存期延长 ,并有利于肿瘤细胞逃避机体的免疫监视及放、化疗等引起的细胞死亡 ,是肿瘤发生、发展的重要机制之一。凋亡抑制蛋白 (inhibitorofapoptosispro tein ,IAP)是抑制细胞凋亡的重要成 Modern tumor research found that cell proliferation and apoptosis regulation disorders is a common phenomenon, suppressed cell apoptosis makes tumor cells to extend the life span, and is conducive to tumor cells to escape the body’s immune surveillance and radiotherapy, chemotherapy and other cell death caused by cancer Occur, develop one of the important mechanisms. Inhibitor of apoptosis (inhibitor ofapoptosis protein, IAP) is an important factor in the inhibition of apoptosis
