线粒体功能异常与肿瘤的生成

Essential role of mitochondria in tumorigenesis

摘要:

肿瘤的发生是一个多种信号网络相互参与调节的复杂过程，随着进程的继续，肿瘤细胞逐渐表现出无限增殖、抵抗凋亡、逃避免疫监督、侵袭与转移以及出现异常的代谢途径等标志性特征。线粒体作为一种独特的细胞器，其在细胞能量代谢、氧自由基生成和细胞凋亡等过程中的作用都与肿瘤细胞的发生密切相关。文中就近年来线粒体功能异常在肿瘤发生、形成中所发挥的作用进行综述。

Abstract:

Tumorigenesis is a complex process that is regulated by a variety of network signals. With the continuous development of the process, tumor cells gradually exhibit lots of hallmarks.Tumor cells have the characteristics of unlimited proliferation, resistance to apoptosis, evading immune surveillance, among others. As a unique organelles, mitochondria play an important role in cellular energy metabolism, reactive oxygen species producing and apoptosis process. Particularly, mitochondria have a close relationship with tumor development. In this review, we focus on the essential role of mitochondria in tumor cells development.
