Daily Gene Rhythms May Be Off in Depressed People

MONDAY, May 13 (HealthDay News) -- Just like you, the genes in your brain follow a daily routine. But that natural rhythm may be thrown off in people with depression, a new study suggests.

Researchers say the findings shed new light on what goes wrong in the brain when depression strikes. And they hope the results, published online Monday in the journal Proceedings of the National Academy of Sciences, could spur new therapies down the road.

It has long been known that your body processes follow daily circadian rhythms, and that the "master clock" orchestrating it all exists in the brain. That clock mainly responds to light and darkness in your surroundings.

Scientists have also thought that gene activity in animals' brains follows a daily ebb and flow. But seeing whether that's true in the human brain is a lot tougher, said researcher Huda Akil.

If you want to look for daily rhythms in hormone activity, Akil said, you can take multiple blood samples from the same people over the course of 24 hours. You cannot, however, investigate the brain that way.

To get around the problem, Akil's team studied autopsied brain tissue from 89 people who had died at different times of day. That way, they could look at each person's gene activity at the time of death and search for differences from one individual to the next.

"Hundreds of genes emerged as having a rhythm based on the time of day," said Akil, a professor of neuroscience and psychiatry at the University of Michigan in Ann Arbor.

That rhythm was clear in brain tissue from the 55 people with no history of psychiatric disorders. Akil said her team was able to look at an individual's gene activity and correctly guess that person's time of death within an hour.

They could not, however, do that for the 34 individuals who were suffering from major depression at the time of death. Their gene activity pat
