线粒体是调节细胞凋亡的承诺和执行的细胞器。内在凋亡途径在线粒体外膜的透化和细胞的解体中达到高潮。当给予化疗治疗时,癌细胞的凋亡是有利的结果,但为什么一些癌症对化疗敏感而另一些癌症对化疗不敏感的基础在历史上一直知之甚少。在这篇综述中,我们提出了最近的工作,已经证明了线粒体凋亡启动的重要性,或如何接近细胞凋亡的阈值,在确定细胞是否会经历化疗治疗后的凋亡。肿瘤中不同水平的凋亡引发为有效使用靶向和细胞毒性化疗创造了真正的机会和挑战。
Mitochondria are cellular organelles that regulate commitment and execution of apoptosis. The intrinsic apoptotic pathway culminates in the permeabilization of the mitochondrial outer membrane and dismantling of the cell. Apoptosis of cancer cells is a favorable outcome when administering chemotherapeutic treatment yet the basis for why some cancers are sensitive to chemotherapy while others are not has historically been poorly understood. In this review, we present recent work that has demonstrated the importance of mitochondrial apoptotic priming, or how close a cell is to the threshold of apoptosis, in determining whether a cell will undergo apoptosis after chemotherapy treatment. Differential levels of apoptotic priming in tumors create bona fide opportunities and challenges for effective use of targeted and cytotoxic chemotherapies.
