Summary
Little is known about the mechanisms that control limb development. We have discovered a new gene which is active in the developing limb of the embryo. This study will provide information on how this new gene controls the development of the limb. Limb defects occur in 1 in 1,000 new-born babies. We believe the absence of our newly discovered gene may be responsible for some of these limb defects. Ultimately, this fundamental knowledge may lead to improved pre-natal diagnosis and better treament ....Little is known about the mechanisms that control limb development.

Summary
There are close to 400 inherited disorders that affect how the skeleton develops, as well as a range of injury and age-related skeletal defects. There is much interest in treating such abnormalities with artificial bone grown outside the body. In order to achieve this aim we must understand all of the processes involved in producing and maintaining bone within the body. We are using both mouse and cell culture models of skeletal development to increase our understanding of these processes.
Improving Kidney Transplant Outcomes Using Normothermic Machine Perfusion

Summary
Kidneys donated for transplantation are at risk of damage that prevent the organ from working and reduce its lifespan. Normothermic machine perfusion is a device that can circulate oxygenated blood at normal body temperature through a donor kidney prior to transplantation. In doing so it is able to resuscitate the kidney and prevent injury. We will determine how machine perfusion achieves this remarkable effect and investigate new treatments for kidney injury.

Summary
Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in b ....Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in both limb and face development. Based on the organs in which our genes of interest are active, we believe that they will also play key roles in embryonic development of the limbs, face and other organs. We now plan to investigate the regulation of a subset of these genes based on analysis in mouse models of limb and face development. In addition, we have chosen to further analyse the function of a completely novel gene we have identified which our preliminary studies suggest may play a role in the normal development of the lip and palate. These studies have the potential to shed light on the processes governing how organs develop, as well as on the molecular basis of common birth defects such as polydactyly (extra fingers and toes) and cleft palate.Read moreRead less
