Scientists Find Mechanism To Reset Body Clock

Researchers from The University of Manchester have discovered a new mechanism that governs how body clocks react to changes in the environment.

And the discovery, which is being published in Current Biology, could provide a solution for alleviating the detrimental effects of chronic shift work and jet-lag.

(snip)

The research identifies a new mechanism through which our clocks respond to these light inputs. During the study, mice lacking CK1epsilon, a component of the clock, were able to shift to a new light-dark environment (much like the experience in shift work or long-haul air travel) much faster than normal.

The research team went on to show that drugs that inhibit CK1epsilon were able to speed up shift responses of normal mice, and critically, that faster adaption to the new environment minimised metabolic disturbances caused by the time shift.

Dr Bechtold said: "We already know that modern society poses many challenges to our health and wellbeing - things that are viewed as commonplace, such as shift-work, sleep deprivation, and jet lag disrupt our body's clocks. It is now becoming clear that clock disruption is increasing the incidence and severity of diseases including obesity and diabetes.

"We are not genetically pre-disposed to quickly adapt to shift-work or long-haul flights, and as so our bodies' clocks are built to resist such rapid changes. Unfortunately, we must deal with these issues today, and there is very clear evidence that disruption of our body clocks has real and negative consequences for our health."

He continues: "As this work progresses in clinical terms, we may be able to enhance the clock's ability to deal with shift work, and importantly understand how maladaptation of the clock contributes to diseases such as diabetes and chronic inflammation."

Interesting, as I have gotten older I find that I am less able to deal with any change in my normal sleep pattern. If I stay up too late it can affect me for the next two or three days.
