ABSTRACT
Reactive oxygen species (ROS) are the chemical species that includes the superoxide anion, hydrogen peroxide and hydrogen radical. These ROS are simply thought as a group of molecules harmful to cells because they oxidize proteins, lipids and DNA, and they mediate cell death including apoptosis or necrosis. On the other hand, ROS have been shown to act as essential intracellular second messengers for certain cytokines and growth factors. Although the importance of ROS in the execution of cell death is controversial, ROS are likely to be involved in the signal transduction mechanism for cell death as signaling intermediates in death receptor initiated signaling pathways, specifically in the tumor necrosis factor alpha-tumor necrosis factor receptor 1 (TNFalpha-TNFR1) pathway. In this review, using TNFalpha-TNFR as the model system, we attempt to address the involvement of intracellular ROS in TNFalpha induced cell death, including apoptosis, necrosis and an alternative form of programmed cell death, necroptosis.
