Hoffmann La Roche, and led by senior research scientist Stuart Peirson at the Nuffield Department of Clinical Neurosciences, identified roughly 100 genes that the body switches on in response to light, initiating a series of events that help to retune the body clock. They identified one gene and its corresponding protein product, called SIK1, that limits the body clock's ability to adjust to changes in the daily patterns of light and dark. In one particular experiment, when the researchers blocked the activity of SIK1 in laboratory mice, the mice adjusted faster to changes in the light-dark cycle that mimic a time zone change. The study proposes that the light-stimulated production of SIK1 in turn switches off the molecular pathway that feeds into the clock mechanism, thereby halting the shifting response of the biological clock.
