What can a worm or fish tell us about the human body? When it comes to biology, quite a lot actually. Learn how UC Davis researchers are using animal models to answer basic biological questions that will build the foundation for revolutions in human health in the new feature story "A Menagerie of Model Organisms."

Engineering a Balanced Diet? Hormone FGF21 Promotes Protein Preference

May 13, 2019
In a study appearing in Endocrinology, Associate Professor Karen Ryan and her colleagues identified the hormone fibroblast growth factor-21 (FGF21) as a control for regulating dietary protein intake in male mice. They found that male mice injected with the hormone increased their intake of dietary protein over carbohydrates and fats.
