Summary
Common fragile sites are regions on human chromosomes that everybody has. These regions are much more sensitive to damage from agents in the environment (including the diet) than other regions in human chromosomes - so when damage does occur it is more likely to occur at these fragile sites. Many of the most sensitive fragile sites have large genes that span them. We need to understand the function of these genes to see how their disruption can contribute to cancer.

Summary
Substantial evidence indicates that in utero environment influences the risk of developing some diseases later in life; this is known as fetal programming. We hypothesize that the in utero environment alters epigenetic marks in the fetus and changes gene expression, leading to disease later in life. We will investigate epigenetic changes in mice born to obese mothers. Better understanding of the mechanisms underlying fetal programming will result in improved administration of public health.
Many recent gene mapping efforts have focused on population based approaches instead of previously used family based approaches. One of the limiting factors with population based approaches is the cost of the technology - each participant must be evaluated (or genotyped) for hundreds of thousands of genetic markers. The cost can be reduced by using an approach which pools individuals together for genotyping, with statistical models used to deal with the problems that this creates.

Summary
Genes contain the information to build our body and keep it operating normally. These genes are inherited from our parents and number around 100,000. Faults in these genes can cause inherited diseases such as cystic fibrosis, cancers and common disorders such as Asthma and diabetes. These genes need detecting so that particular genes can be identified as causing the disease and also so that patients can have their disease properly diagnosed so that proper therapy and information can be given to ....Genes contain the information to build our body and keep it operating normally. These genes are inherited from our parents and number around 100,000. Faults in these genes can cause inherited diseases such as cystic fibrosis, cancers and common disorders such as Asthma and diabetes. These genes need detecting so that particular genes can be identified as causing the disease and also so that patients can have their disease properly diagnosed so that proper therapy and information can be given to the patients. In future similar changes (but changes not causing disease) may be searched for in patients to overcome the side effects of drugs. Our centre specializes in the methods of detecting faults and their application. Two of our methods are being used around the world and one is being sold as simple kit. These methods still have drawbacks and the work proposed is to overcome some of these. We propose to apply our and other methods to faults in genes which have recently been shown to cause diseases of the artery. This is an exciting new development that shows that this disease is similar to cancer. We are fortunate to have attracted Dr Paula Bray from the laboratory which discovered this. This new finding needs to be studied in more detail and may identify life-style factors which cause coronary heart disease. Our studies will also assist in gene therapy when it becomes available.Read moreRead less
