Role of reactive oxygen species in ultraviolet-induced photodamage of the skin.
Reactive oxygen species (ROS), such as superoxides (O2 •-) and hydroxyl groups (OH·), are short-lived molecules containing unpaired electrons. Intracellular ROS are believed to be mainly produced by the mitochondria and NADPH oxidase (NOX) and can be associated with various physiological processes, such as proliferation, cell signaling, and oxygen homeostasis. In recent years, many studies have indicated that ROS play crucial roles in regulating ultraviolet (UV)-induced photodamage of the skin, including exogenous aging, which accounts for 80% of aging. However, to the best of our knowledge, the detailed signaling pathways, especially those related to the mechanisms underlying apoptosis in which ROS are involved have not been reviewed previously. In this review, we elaborate on the biological characteristics of ROS and its role in regulating UV-induced photodamage of the skin.
期刊介绍：
Cell Division is an open access, peer-reviewed journal that encompasses all the molecular aspects of cell cycle control and cancer, cell growth, proliferation, survival, differentiation, signalling, gene transcription, protein synthesis, genome integrity, chromosome stability, centrosome duplication, DNA damage and DNA repair.
Cell Division provides an online forum for the cell-cycle community that aims to publish articles on all exciting aspects of cell-cycle research and to bridge the gap between models of cell cycle regulation, development, and cancer biology. This forum is driven by specialized and timely research articles, reviews and commentaries focused on this fast moving field, providing an invaluable tool for cell-cycle biologists.
Cell Division publishes articles in areas which includes, but not limited to:
DNA replication, cell fate decisions, cell cycle & development
Cell proliferation, mitosis, spindle assembly checkpoint, ubiquitin mediated degradation
DNA damage & repair
Apoptosis & cell death
