Single gene controls jet lag

Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms.

The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers or jet lagged travelers adjust to time differences more quickly. The results, published in eLife, can point to treatment strategies for sleep problems caused by a variety of disorders.

“It’s possible that the severity of many dementias comes from sleep disturbances,” says Satchidananda Panda, a Salk associate professor who led the research team. “If we can restore normal sleep, we can address half of the problem.”
