Male and female behavior deconstructed
Date:2/2/2012

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how?

Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

The UCSF team selectively turned many of these genes off one by one and found they could manipulate individual behaviors in the mice, like their sex drive, desire to pick fights, or willingness to spend extra time caring for their young.

"It's as if you can deconstruct a social behavior into genetic components," said Nirao Shah, MD, PhD, an associate professor in the Department of Anatomy at UCSF who led the research, which is published in the 2/3/12 issue of the journal Cell. "Each gene regulates a few components of a behavior without affecting other aspects of male and female behavior.

In addition to illuminating the role of genes in male and female behavior, Shah said, the results also have greater implications: If male and female behaviors can be broken down into individual component parts, what other complex behaviors could similarly be deconstructed?

Identifying how genetic differences in our brains account for the differences in our behavior may also be a starting point for understanding how to better address human mental illness and neurodegenerative conditions in which such gender differences exist. For example, autism is four times more common in males than in females.

"Some of the genes we have identified in our study have indeed been implicated in various human disorders that are found in sex-skewed ratios," said Shah. "We won't immediately find all the answers to these disorders based on this research alone, but in the future, it might indeed help to ide
