Study Tracks Brain Gene Response to Territorial Aggression
Date:11/15/2012

CHAMPAIGN, Ill. With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away.

Now researchers are mapping the genetic underpinnings of the stickleback's aggressive behavior. Armed with tools that allow them to see which genes are activated or deactivated in response to social encounters, a team from the University of Illinois has identified broad patterns of gene activity that correspond to aggression in this fish.

A paper describing their work appears in the Proceedings of the Royal Society: Biological Sciences.

"The molecular mechanisms underlying complex behaviors such as aggression are a challenge to study because hundreds of genes are involved, and in order to study them, we have to delve into arguably the most complex tissue: the brain," said Illinois animal biology professor Alison Bell, who led the study.

The researchers looked at brain gene expression the pattern of genes that were activated or deactivated across four brain regions in the nesting stickleback fish shortly after it encountered an intruder. They compared the brains of nesting stickleback males that did and did not encounter an intruder, to identify how the experience of fending off a challenger changed gene expression in the brain.

"Territorial aggression and other behaviors in sticklebacks have been well-studied by astute observers of animal behavior for almost a century, but complex behaviors in wild animals require the use of powerful tools to understand them," Bell said. "Until recently we have not had sophisticated computational and genomics tools to delve into the causes of aggression in real organisms in natural populations."

The analysis revealed that hundreds of genes were upregulated (activated at higher leve
