Abstract

We established an anti-ErbB-2 mouse-human chimeric monoclonal antibody (MoAb), CH401, which was able to kill cancer cells overexpressing the ErbB-2 protein in vitro. The analysis of the killing mechanism indicated that MoAb CH401 might be the first anti-erbB-2 mouse-human chimeric MoAb which can induce the apoptosis of cancer cells, since morphological changes and DNA fragmentation were recognized in MoAb CH401-treated cells. The ErbB-2 receptor appears to have two opposing functions: acting as a receptor both for a growth factor and for an apoptotic factor. Our results indicate that MoAb CH401 treatment may prove to be very useful for cancer therapy.

摘要

我们制备了一种抗ErbB-2小鼠-人嵌合单克隆抗体(MoAb)CH401,它能够在体外杀死过表达ErbB-2蛋白的癌细胞。对杀伤机制的分析表明,MoAb CH401可能是首个能够诱导癌细胞凋亡的抗ErbB-2小鼠-人嵌合单克隆抗体,因为在经MoAb CH401处理的细胞中观察到了形态学变化和DNA片段化。ErbB-2受体似乎具有两种相反的功能:作为生长因子和凋亡因子的受体。我们的结果表明,MoAb CH401治疗可能对癌症治疗非常有用。
