Zebrafish finds a new role in human studiesZebrafish, an important animal model in disease and environmental studies, can offer the means for helping scientists eventually disclose the function of a mysterious enzyme linked to the steroid cortisol, and found in the human brain.

Steroids such as cortisol perform a variety of duties like bone formation, brain activity, and immune response regulation in humans and other vertebrates.

Baker was able to find that genomes of mice and rats do not contain 11 beta-HSD3 that suggest that inserting the appropriate gene for the enzyme in these animal models may result in additional investigation avenues.
