Evening exposure to blue light stimulates the expression of the clock gene <i>PER2</i> in humans

1 Feb 2006

Abstract excerpt

We developed a non-invasive method to measure and quantify human circadian PER2 gene expression in oral mucosa samples and show that this gene oscillates in a circadian (= about a day) fashion. We also have the first evidence that induction of human PER2 expression is stimulated by exposing subjects to 2 h of light in the evening. This increase in PER2 expression was statistically significant in comparison to a...
