Abstract
Reactive oxygen species (ROS) are a kind of highly active oxygenated compounds, which can produce oxidative reactions in the body and be scavenged by the antioxidant system under normal physiological conditions. The imbalance between oxidant and antioxidant leads to excessive production and accumulation of reactive oxygen species, which can cause oxidative damage of DNA, lipid and protein in cells and induce malignant transformation of cells. In addition, ROS can also play a dual role as a signal molecule by participating in regulating different signal transduction pathways. On the one hand, ROS can induce the proliferation, improve tolerance and promote the metastasis of cancer cells; on the other hand, ROS can induce apoptosis or even necrosis of cancer cells. Therefore, ROS are closely related to the occurrence and development of tumors and can be used as an important target for cancer treatment.
Key words:
Neoplasms; Oxidants; Antioxidants; reactive oxygen species
