Funded Activity Summary

The Eph family of proteins were initially found to be important in normal development. In humans this corresponds to the first 12 weeks of pregnancy. In parallel with these studies, other work provided evidence of abnormally high levels of these proteins in a number of human cancers. More recent evidence suggests that these proteins have important roles in the maintenance of normal tissues and in non-malignant diseases. This proposal seeks to understand how one of these proteins (EphA1) works in the cells which form the skin, liver, kidneys, breast and prostate. These cells also form the lining of the mouth, stomach, bowel and lungs. Understanding how the EphA1 protein and other members of this family cooperate to control the development and maintenance of these organs will allow us to determine whether this protein might be involved in congenital defects and diseases in these organs (such as kidney failure, cirrhosis of the liver and skin diseases). A second main aim of this project is to explore further the observation that Eph proteins are abnormally highly expressed in a wide rangre of human cancers. This abnormal expression is directly correlated with the tumours spreading throughout the body. EphA1 is abnormally highly expressed in cancers of the bowel, lung, breast and prostate. These are the commonest cancers in man and some of the most difficult to treat. The work proposed asks how EphA1 contributes to the development and progression of these cancers. These results will have very direct implications for the development of therapies which target the EphA1 protein.
