Summary
The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this stud ....The cells of the skin play an essential role in development of the mammalian embryo. They are critical for closure of the brain and spinal cord, for forming a protective barrier against infection and noxious stimuli, for preventing excess fluid loss, for repair of defects and wounds, and for the generation of hair. Our laboratory has identified a family of genes that are critical for all these processes. Loss of individual members of the family has different consequences and the aim of this study is to determine the relationship between the genes to further our understanding of the skin and its functions. These studies have direct and important relevance to human conditions such as the congenital birth defects spina bifida and anencephaly, and infant prematurity where the skin is underdeveloped and lacks barrier function. They also have relevance to wound healing and to conditions in which hair growth is affected, such as alopecia. We believe that therapeutic interventions and prenatal diagnostic tests could evolve from these studies.Read moreRead less

Summary
Rare genetics diseases can often provide us with insights into some of the fundamental mechanisms which control how we develop and live healthy lives. We have identified a family of genes called the Fras and Frem genes and some of these are mutated in a disorder called Fraser Syndrome. Fraser Syndrome patients have profound defects in the normal development of their skin and kidneys. We are studying the function of these genes with a view to understanding not just how Fraser Syndrome develops, b ....Rare genetics diseases can often provide us with insights into some of the fundamental mechanisms which control how we develop and live healthy lives. We have identified a family of genes called the Fras and Frem genes and some of these are mutated in a disorder called Fraser Syndrome. Fraser Syndrome patients have profound defects in the normal development of their skin and kidneys. We are studying the function of these genes with a view to understanding not just how Fraser Syndrome develops, but how our organs develop normally. The genes involved in FS contribute to the extracellular matrix which is effectively the scaffolding which our cells use when developing into our organs. The extracellular matrix is also important in maintaining our adult tissues and responding to damage. It can act as a physical support and as a key controller of how ours cells react to growth factors and to each other. This proposal will explore how the Fras and Frem genes mediate these interactions to control normal development and also to determine how their mutation gives rise to disease. In doing so we hope to gain insights into more common diseases which affect both the kidney and the skin.Read moreRead less
