Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.

Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is essential for formation and repair of the skin barrier. We have identified a family of genes that are pivotal for skin development and function. Disruption of these genes has disastrous consequences, including loss of barrier function and the development of skin cancers. This project examines how these diseases occur.
Hepatocellular carcinoma (HCC), or liver cancer, is a major global problem. Most people present with advanced disease and current therapies are relatively ineffective. Small RNAs, called microRNAs are a new form of therapy that may present new options for patients with HCC. We have characterised a microRNA that is a powerful inhibitor of HCC growth both in cells and in preclinical animal models. This project will characterise the microRNA’s function in HCC and as a potential therapeutic.

Summary
Hormones bind to receptors on the surface of cells. Receptors can modify each other’s function and this “cross-talk” is important for the receptors for a peptide hormone (termed angiotensin) and a growth factor receptor (EGFR), which are major regulators of the cardiovascular system. We have identified a number of mediators of the angiotensin-EGFR crosstalk and this current grant aims to use molecular and cellular and in vivo approaches to examine the molecular basis of their actions.
From Pathogenesis To Therapeutics: Targeting Two Signalling Pathways As A Therapeutic Strategy To Treat Preeclampsia

Summary
Preeclampsia is a serious complication of pregnancy that claims the lives of thousands of mothers and babies each year. There is no efficacious medical treatment besides delivery of the baby and placenta. Our lack of therapeutics is largely a result of our poor understanding of the disease. In this application we plan to thoroughly characterise two pathways we believe responsible for preeclampsia, effectively identifying many points at which new therapies could be targeted.
Mechanism Of Epidermal Growth Factor Receptor Transactivation

Summary
This application examines the cellular events that control heart growth in response to angiotensin, a hormone linked to heart failure. We believe that the same cell processes are also involved in cancer cell growth and by understanding the mechanism by which angiotensin promotes growth, better therapies against human cardiovascular disease and its relationship to uncontrolled growth will evolve.
