| Food-energy Cellular Connection Revealed: Metabolic Master Switch Sets Biological Clock In Body Tissues
October 16, 2009 at 8:00 pm
|
| Our body's activity levels fall and rise to the beat of our internal drums -- the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. Whereas the master clock in the brain is set by light, the pacemakers in peripheral organs are set by food availability. The underlying molecular mechanism was unknown. Now, researchers are shedding light on the long missing connection: A metabolic master switch, which, when thrown, allows nutrients to directly alter the rhythm of peripheral clocks. |
