Abstract:

Reactive Oxygen Species (ROS) are widely present in the body's metabolic response, but their concentrations in tumor cells of different differentiation are significantly different. Oxidative stress is caused by the imbalance of the oxidation system and the antioxidant system of the human body. In contrast to general cancer cells in which ROS levels are increased, cancer stem cells (CSCs) exhibit lower levels of ROS. CSCs have attracted much attention of the research community in recent years, since they are the key to tumor genesis and development, and their unique metabolic characteristics may be the key to their drug resistance. It is possible to selectively kill CSCs by increasing the concentration of ROS in CSCs or to increase the sensitivity of CSCs to radiotherapy and chemotherapy

Key words: Cancer stem cells, Reactive oxygen species, Glycolysis, Oxidative phosphorylation
