Researchers at UCLA are investigating the role of a sleep-regulating gene in the skeletal muscle of mice.
“When we first saw the importance of the muscle, we were surprised,” said senior author Ketema Paul, UCLA associate professor of integrative biology and physiology. “At first we didn’t believe it, so we repeated the experiment several times. We finally realized this is not a mistake; this is real.”
The research, published in the journal eLife, is the first evidence that a biological clock in the muscle can communicate with the brain, and is potentially good news for people who lose sleep because of factors including a crying newborn or a job that does not allow for normal sleep cycles, such as active military service.
