Establishment of the endocrine axes in the embryo and their xenobiotic distortion

Millions of tons of supposedly harmless chemicals are produced and enter the environment each year. However, some of these substances can act on wildlife and humans to distort the way that hormone systems are established in the embryo, leading to subtle effects on health and function in later life. We will use one of the commonest of these substances, found in many cosmetics, food wrappings, and medicinal plastics, to learn how hormone systems becomes established in a healthy embryo, and how these then get distorted after exposure to these compounds. This project directly addresses the way we assess the health of our environment, and offers ways to screen for compounds which can have subtle effects on wildlife, domestic species and humans.
