Abstract

Reactive oxygen species (ROS), such as superoxides (O 2 •−) 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.

  • Salvage-mediated recycling of nucleotides plays a pivotal role in maintaining genomic stability in dermal cells exposed to UV radiation and ROS.

    “In addition to fueling DNA synthesis, salvage-mediated recycling of nucleotides plays a pivotal role in maintaining genomic stability, particularly in dermal cells exposed to extrinsic insults (e.g., UV radiation) and intrinsic stressors (e.g., mitochondrial-derived reactive oxygen species (ROS)) [81,82].”

    From Comparison of Polynucleotide and Polydeoxyribonucleotide in Dermatology: Molecular Mechanisms and Clinical Perspectives (2025) · cites this paper as [81]

    The 'DNA damage by ROS' and 'Mitochondrial DNA damage and apoptosis by ROS' sections discuss UV- and ROS-induced DNA damage and DNA excision repair, but do not address whether salvage-mediated nucleotide recycling maintains genomic stability. Searches for nucleotide salvage and recycling found no passage supporting that mechanism. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
