Jet Lag Gene Could be Target for New Drug
Can we beat the clock? Jet lag sufferers may soon breeze through time zone changes with the help of a pill. Scientists have identified a gene called Lhx1, a master clock of sorts that controls circadian rhythms and brain receptors that respond to light. Researchers have discovered that reducing Lhx1 levels helps lab mice adjust to a simulated jet-setting environment. If drug makers can concoct a drug to suppress the Lhx1 effect, it could soon mean having time on our side.
