UV-B light at a certain dose changes how a key body-clock gene behaves in skin cells, suggesting sunlight might reset the skin’s internal clock all on its own.

Differential Regulation of Circadian Clock Genes by UV-B Radiation and 1,25-Dihydroxyvitamin D: A Pilot Study during Different Stages of Skin Photocarcinogenesis

Cross-Sectional Study

In Vitro

2024 Jan 14

The study shows that UV-B light changes the activity and timing of a key body-clock gene in skin cells, which supports the idea that sunlight directly affects the skin's daily rhythms.

UV-B light and vitamin D affect our skin cells' internal clocks in totally different ways — and vitamin D doesn’t explain how UV-B changes those clocks.

In normal skin cells, the body's daily clock for a key protein (BMAL1) works well, but in certain skin cancer cells, that clock barely works at all — suggesting the clock breaks down as skin cells turn cancerous.
