摘要:

无法彻底清除肿瘤干细胞(cancer stem cells,CSCs)被认为是肿瘤治疗过程中的一个巨大障碍。CSCs是一群存在于异质性肿瘤组织中的细胞亚群,它们具有自我更新和分化的潜能。作为一个功能性的概念,CSCs能够表现出启动肿瘤发生、抵抗放射治疗与化学治疗(化疗)以及导致肿瘤复发等恶性行为。有关CSCs多方面的研究已被陆续开展,包括特异性的细胞表面标志、自我更新信号通路以及表观遗传调控等,然而CSCs代谢却未得到足够的关注。基于现有的相关研究,该文综述了CSCs的能量和物质代谢特性,并从代谢角度探讨了CSCs在导致肿瘤治疗抗性与复发中的作用,同时还阐述了CSCs代谢与表观遗传调控的密切联系,并强调靶向CSCs代谢在肿瘤治疗中具有巨大的潜在价值。

Abstract:

The inability to fully eradicate cancer stem cells (CSCs) is considered to be a huge obstacle in tumor therapy. CSCs can be defined as a subpopulation of cells within heterogeneous tumors that have the potential for self-renewal and differentiation. They can also drive malignant behaviors, such as tumor initiation, resistance to chemotherapy and radiotherapy, and tumor relapse. Multiple aspects of CSCs have been studied, including specific cell surface markers, self-renewal pathways and epigenetic regulation. However, relatively little attention has yet been directed towards to the metabolism of CSCs. Based on the relevant research we currently know, here we review the properties of the energy and substance metabolism in CSCs, and we also discuss the role of CSCs in therapy resistance and tumor relapse from a metabolic perspective. In addition, we describe the linkage between CSCs metabolism and epigenetic regulation. Therefore, we highlight the huge therapeutic potential of targeting CSCs metabolism in tumor therapy.

Key words: cancer stem cell (CSC), metabolism, therapy resistance, tumor relapse, epigenetic regulation, tumor therapy
