UV radiation increases phenolic compound protection but decreases reproduction in Silene littorea.

PLoS ONE, 2020
Plants respond to changes in ultraviolet (UV) radiation both morphologically and physiologically. Among the variety of plant UV-responses, the synthesis of UV-absorbing flavonoids constitutes an effective non-enzymatic mechanism to mitigate ...

UV Radiation and the Skin [PDF]

International Journal of Molecular Sciences, 2013
UV radiation (UV) is classified as a “complete carcinogen” because it is both a mutagen and a non-specific damaging agent and has properties of both a tumor initiator and a tumor promoter.

UV Radiation and Its Relation to DNA Methylation in Epidermal Cells: A Review

Epigenomes, 2020
DNA methylation is the most studied epigenetic mark, and it can be altered by environmental factors. Among these factors, ultraviolet radiation (UV) is little explored within this context.

Photoaging: UV radiation-induced inflammation and immunosuppression accelerate the aging process in the skin

Inflammation Research, 2022
Excessive exposure of the skin to UV radiation (UVR) triggers a remodeling of the immune system and leads to the photoaging state which is reminiscent of chronological aging.
