A team of researchers at Dartmouth Medical School has identified a gene that could be targeted to help jet-lagged travelers or workers on a late shift adjust their bodies' internal clocks to new schedules.
The team primarily studies the genetics and molecular biology of the circadian clock, a regulatory mechanism that drives many of the body's physiological processes including the sleep cycle, genetics department chair Jay Dunlap, one of the researchers involved with the study, said in an interview with The Dartmouth.
The researchers decided to investigate the gene, named Id2, after tests indicated that it could be involved in the circadian system.
The circadian clock dictates sleep patterns based on the natural light-dark cycle, Dunlap said, regardless of whether an individual is awake at night.
"Even though you're on shift work, it doesn't mean that the clock is resetting," he said.
