Various antitumor agents induce apoptotic cell death in tumor cells. Since the apoptosis program in tumor cells plays a critical role in the chemotherapy-induced tumor cell killing, it is suggested that the defect in the signaling pathway of apoptosis could cause a new form of multidrug resistance in tumor cells. This article describes the recent findings concerning the mechanisms of chemotherapy-induced apoptosis and discusses the implication of apoptosis resistance in cancer chemotherapy.
各种抗肿瘤药物可诱导肿瘤细胞发生凋亡性细胞死亡。由于肿瘤细胞中的凋亡程序在化疗诱导的肿瘤细胞杀伤中起着关键作用,因此,凋亡信号通路的缺陷可能导致肿瘤细胞产生一种新的多药耐药形式。本文描述了关于化疗诱导细胞凋亡的机制的最新发现,并讨论了凋亡抵抗在癌症化疗中的意义。
