Redox regulation is a field of research that focuses on the balance of oxidants and antioxidants in biological systems, particularly within cells. This balance, often referred to as redox homeostasis, is critical for maintaining proper cell function and response to various cellular stresses. Redox regulation involves the control of redox signaling pathways, which play a role in cell growth, differentiation, and apoptosis. Dysregulation of redox homeostasis can lead to oxidative stress, which is implicated in numerous diseases such as cancer, neurodegenerative disorders, and cardiovascular diseases. Understanding redox regulation is therefore important for developing new therapeutic approaches for these diseases.
