Antioxidants & Redox Signaling (ARS) is the leading peer-reviewed journal dedicated to understanding the vital impact of oxygen and oxidation-reduction (redox) processes on human health and disease. The Journal explores key issues in genetic, pharmaceutical, and nutritional redox-based therapeutics. Cutting-edge research focuses on structural biology, stem cells, regenerative medicine, epigenetics, imaging, clinical outcomes, and preventive and therapeutic nutrition, among other areas.ARS has expanded to create two unique foci within one journal: ARS Discoveries and ARS Therapeutics. ARS Discoveries (24 issues) publishes the highest-caliber breakthroughs in basic and applied research. ARS Therapeutics (12 issues) is the first publication of its kind that will help enhance the entire field of redox biology by showcasing the potential of redox sciences to change health outcomes.ARS coverage includes:-ROS/RNS as messengers-Gaseous signal transducers-Hypoxia and tissue oxygenation-microRNA-Prokaryotic systems-Lessons from plant biology
