Summary
Skeletal muscle regeneration following injury is a tightly regulated process and any disturbance to this process, such as that which occurs with the muscular dystrophies, can greatly impair a muscle's ability to regenerate. The aim of this project is to better understand the mechanisms that control muscle regeneration, and open up new avenues for potential treatment strategies in conditions where muscle wasting and weakness are indicated.

Summary
Elucidation of cell cycle regulation in the proliferating pluripotent cells of the early mammalian embryo is likely to have important impact on basic scientific knowledge, and on the development of novel therapeutic strategies. Investigation of this problem, in vitro and in vivo, requires specialist skills in cell cycle analysis, and experimental manipulation of mammalian embryos and pluripotent cells.

Investigation of this problem, in vitro and in vivo, requires specialist skills in cell cycle analysis, and experimental manipulation of mammalian embryos and pluripotent cells. This application will seek to address these fundamental issues of early development and cell proliferation using molecular approaches. The general aims will be: 1. to obtain a detailed description of cell cycles in pluripotent and differentiating cells of the mouse embryo 2. use this information to build a molecular description of cell cycle events during early embryogenesis 3. investigate the relationship between rapid cell proliferation in the embryo and pluripotencyRead moreRead less

Summary
The aim of this research is to study how white blood cell growth is regulated by signals of the immune system. Problems in this process can have drastic effects on the well being of an individual leading to deficiencies in controlling infection and development of diseases such as cancer. Once we understand how these signals regulate white blood cell growth, we can begin to develop therapies to provide protection against these diseases.

Summary
The immense potential of gene therapy has been confirmed by the successful treatment of immune deficiencies disorders. A key issue that has emerged however is the need to avoid potentially cancer-causing genetic damage to cells undergoing repair. Some of this risk can be linked to the gene repair technology used, but we have identified and propose to investigate another potentially important mechanism involving the unusually high levels of replication imposed on cells during disease correction.
This established team of investigators will research into the molecular control of white blood cell formation and function, using a multidisciplinary, team approach to fundamental biological questions with a focus on potential clinical and commercial outcomes. The team will also attempt to identify new validated targets for therapeutic intervention by using both forward and reverse genetic approaches in mice coupled with complete phenotypic analyses of the blood cell system.

Summary
Cancer is characterised by changes in several fundamental cellular processes including the failure of the cancer cells to stop growing in response to the body's normal stop signals.. When cells normally stop growing there is profound changes in the activity of many genes. This proposal aims to investigate how these changes in gene activity are brought about. We propose that a recently discovered family of genes called SWI-SNF work with two other families of genes (the Mad-family and Rb-family) t ....Cancer is characterised by changes in several fundamental cellular processes including the failure of the cancer cells to stop growing in response to the body's normal stop signals.. When cells normally stop growing there is profound changes in the activity of many genes. This proposal aims to investigate how these changes in gene activity are brought about. We propose that a recently discovered family of genes called SWI-SNF work with two other families of genes (the Mad-family and Rb-family) to bring about the cessation of cell growth. If our proposal is proven it will open new avenues to evaluate the growth properties of human cancers and may lead to novel strategies to inhibit cell growth.Read moreRead less
