Oak Brook, IL - The April edition of SLAS Technology features the cover article "Therapeutic Potential of Reactive Oxygen Species: State of the Art and Recent Advances" by Valeria Graceffa, Ph.D. (Institute of Technology Sligo, Sligo, Ireland). The cover article explores the therapeutic potential of reactive oxygen species (ROS) including applications ranging from wound healing and hair growth enhancement, to cancer treatment, stem cell differentiation and tissue engineering. At low concentrations, ROS can be utilized as inexpensive and convenient inducers of tissue regeneration, triggering stem cell differentiation and enhancing collagen synthesis. Recent cancer studies have represented ROS as the 'Achilles Heels' of cancers given their high basal levels, leaving tumoral cells unable to sufficiently handle the additional source of oxidative stress. Because of this, higher doses of ROS are used for targeted killing of tumor cells. Lack of understanding of the technicalities between anabolic and cytotoxic effects means limited ROS clinical translation opportunities. While there is ample potential for the use of ROS, new strategies to control temporal pattern of ROS release have yet to be developed.
