...sleep-wake cycle. We’ve only just gotten our foot in the door,” said Associate Professor of Neurobiology Charles J. Weitz ’77, the head of the research team. Although researchers have known about the genes and proteins that cause certain circadian changes, the recent discovery brings to light the actual machinery of the nerve cells, where certain molecular factors are switched on and off to control the daily rhythms...
...chemical factors that control the circadian rhythms work through a receptor known as TGF alpha that then communicates with the nerve cells. The factors regulate daily physical activity, as well as the sleep-wake cycle...
...alpha molecule is not a new discovery—it’s long been known to scientists. But the molecule’s circadian function comes as something of a surprise...
These findings indicate that the body’s circadian clock can be influenced by outside factors as well as its internal mechanisms...
...circadian factors found by the HMS researchers were identified in a hamster. The findings are strengthened by a separate study that shows that mice with deficient quantities of the receptor do not have normal circadian patterns...
