Association between seasonal serum folate levels and ultraviolet radiation

Publication date: Available online 14 November 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Estefanía Valencia-Vera, José Aguilera Arjona, Andrés Cobos, Jean-Luc Bernabó, Vidal Pérez-Valero, Enrique Herrera CeballosAbstractUV radiation has been consistently reported to cause folate photodegradation in vitro and in human skin. Seasonal variations in UV radiation might explain seasonal changes in folate levels in blood. Yet, few studies have addressed this phenomenon. The main objective of this study was to investigate whether a relationship exists between seasonal variations in serum folate levels in a population of Spain (Latitude: 36° 41′ 6.88″; Longitude: 4° 30′ 0.64″) and the annual variations of solar ultraviolet reached in the localization...
