Summary
Our skin protects us from damage, dehydration, infection and harmful UV radiation. At the same time, we expect it to remain healthy, smooth and looking good. How the skin, and more particularly its upper layer, the epidermis, adapts to all these requirements is a complex problem yet to be fully understood.

At the same time, we expect it to remain healthy, smooth and looking good. How the skin, and more particularly its upper layer, the epidermis, adapts to all these requirements is a complex problem yet to be fully understood. This question forms the basis of our project proposal. The epidermis is a continuously self-renewing tissue, in which cells have an average life of 30 days before they are invisibly shed to the outside. In normal states and when responding to injury or disease, this cell turnover speed can be finely tuned, for example accelerated in the case of a healing wound. In contrast, if damaged by the sun, epidermal cells undergo a form of cell suicide (apoptosis) to prevent tumours forming from cells with damaged genes. This changing turnover speed is controlled by a series of growth factors, or cytokines. Insulin-like growth factor-I (IGF-I) is a unique cytokine that can control both cell turnover rate, and cell death. We aim to uncover the complex biochemical interactions that allow the epidermal IGF-I system to achieve this seemingly contradictory task. This study is important because when the epidermis loses the ability to finely tune its turnover speed, ulcers, sun damage, the common skin disorder psoriasis, or worse still, skin tumours, arise. This project explores ways of manipulating the IGF-I system to prevent this, and builds on some technology developed by the research group that has already proven effective in the control of psoriasis. The project also promises to discover undiscovered growth regulators that could be used in new gene therapies for skin overgrowth diseases.Read moreRead less
Developing The Epidemiological Evidence Base For Eczema Prevention

Funding Amount
$476,728.00
Summary
Eczema, food allergy, asthma and hay-fever are all common conditions that are a substantial burden for individuals and families. To prevent them, we need to know their causes, but these are not yet well understood. We need better studies to identify what is causing our children to develop these allergic diseases, and rigorous studies to prevent them. In this fellowship, I will explore the causes and consequences of these conditions and test ways to prevent children from developing them.
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier

Funding Amount
$616,950.00
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.
Topical Drug Delivery Based On Porous Silicon Nanoneedles

Funding Amount
$318,768.00
Summary
There are currently a number of new drugs that can only be administered through the skin via hypodermic needles, which is costly, invasive and carries the risk of infection spread. This project proposes to develop an alternative strategy based on skin patches covered in millions of microscopic porous needles. These needles are able to puncture the skin painlessly to provide rapid and minimally-invasive administration of drugs for treatment of skin diseases, such as melanoma or psoriasis.
Identification Of Critical Factors For The Establishment And Maintenance Of The Epidermal Barrier

Funding Amount
$671,424.00
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.
Development Of A Novel MicroRNA Mimic For Cancer Treatment

Funding Amount
$534,179.00
Summary
Liver cancer is a major health burden globally, with a very poor prognosis. New treatments are urgently needed. We have developed proof-of-concept data showing that a tiny RNA, called a microRNA, is a powerful inhibitor of liver cancer growth. We will use this grant application to further develop the microRNA with novel chemistry so that it can be readily translated into early phase clinical trials in the near future.

The Chief Investigators have extensive experience in the analysis of the molecular defects in colorectal cancer cells and have already developed new drugs to treat successfully experimental colon tumours in animals. During this research program, we will explore these systems further, concentrating on the identification of novel inhibitors of colon cancer cell growth, survival and movement. Newly developed instruments and techniques will allow us to identify and detect the critical steps during the development of colorectal cancer and to design potent drugs to fight the disease. We have experience in conducting novel clinical trials in colon cancer and have developed imaging techniques for monitoring the effectiveness and safety of new anti-cancer drugs. Our collective scientific experience and ability to work in the clinic provides a unique opportunity for developing more effective treatments for colorectal cancer patients.Read moreRead less
