What this Trial Is About
Researchers are studying how the skin of night shift workers responds to artificial sunlight, specifically ultraviolet B radiation (UVB), compared to day shift workers. The study aims to understand differences in DNA repair activity and clock gene expression in skin exposed to UVB at two different times of day. This research focuses on skin cancer risk factors related to work schedules and skin response to UVB radiation. The study involves taking skin punch biopsies from both day and night shift workers. These biopsies will be brought to a laboratory where they will be exposed to UVB radiation or kept as non-irradiated controls. After one hour of incubation from UVB exposure, various DNA repair factors, core clock genes, and DNA damage signaling pathways will be measured. Participants will fall into two groups based on their work schedules: those working primarily daytime shifts and those working primarily night shifts. Participants will provide information about their work schedules over the past three months and undergo skin biopsies for laboratory testing. Researchers will evaluate the expression levels of DNA repair proteins, activity of DNA repair systems, and activation of DNA damage signaling after UVB exposure. The study includes assessments at two times of day to compare biological responses. The total study participation involves skin biopsies and data collection related to work schedules and skin type.
