Summary
Our aim is to discover new genes that greatly increase bowel cancer risk. If we can identify these carriers we may be able to prevent them getting cancer. By studying DNA related to bowel cancer, using a novel family design, we will identify families most likely to carry the new genes. We will focus genetic testing, using new techniques, to look for mutations in these prioritised families. Identified mutations will be tested in a 3,500 bowel cancer cases to see how important they are.

Summary
This study aims to identify genetic factors that influence the development of endometrial and other cancers, and to develop statistical and laboratory methods that can better determine if variation in a known cancer gene is disease-causing. The results will be used to identify and prioritise individuals at greatest risk of cancer for the most appropriate clinical management. Discovery of novel cancer genes will improve our understanding of disease development to develop future therapies.

Summary
The measurement of tumour specific circulating DNA in the blood of women with breast cancer has the potential to be utilised as a personalised biomarker and revolutionise the management of this disease. This project aims to improve our understanding of the relationship between circulating tumour DNA, the progression of cancer, and responses to cancer treatment. Furthermore, it aims to address how this new tool can be integrated into clinical practice to provide benefits for women with breast can ....The measurement of tumour specific circulating DNA in the blood of women with breast cancer has the potential to be utilised as a personalised biomarker and revolutionise the management of this disease.

Assessment Of Mismatch Repair Gene Sequence Variants For Clinical Relevance

Summary
Mutations in mismatch repair genes cause familial cancer. A number of families carry sequence changes that do not obviously alter the gene product, and it is difficult to predict whether these variants are the direct cause of cancer in the family. Consequently, it is not possible to offer informative genetic counselling to these families. We aim to assess the value of several web-based programs, with additional information, to predict the functional changes determined for a panel of variants.

Summary
Recent advances in the field of tumour biology have created strong interest in development of molecularly targeted anti-tumour drugs. These targeted drugs are expected to yield higher therapeutic indices with fewer side effects than conventional cytotoxic treatments. However, due to the complicated nature of cellular processes affected by a given treatment, and the high cost of bringing new drugs to the clinic, it is important to define both mechanisms of action and in vivo functional effects of ....Recent advances in the field of tumour biology have created strong interest in development of molecularly targeted anti-tumour drugs. These targeted drugs are expected to yield higher therapeutic indices with fewer side effects than conventional cytotoxic treatments. However, due to the complicated nature of cellular processes affected by a given treatment, and the high cost of bringing new drugs to the clinic, it is important to define both mechanisms of action and in vivo functional effects of targeted therapies early in the drug development process. Gastrointestinal stromal tumour (GIST) is a prime example of a cancer for which a rationally designed drug has been successfully used. GISTs are often associated with activating mutations in c-kit, a gene encoding a cell surface protein. A new drug, Imatinib, inhibits the activity of mutated c-kit and blocks growth of many GISTs. However, over time many GISTs become resistant to Imatinib creating the need to develop additional treatments. Unfortunately, this has been hampered by lack of both a good model system for testing new drugs and robust diagnostic procedures for defining response to treatment. We have now developed a mouse model of GIST that grows and responds to treatment in a similar manner to human GIST. Furthermore, using imaging technology specifically designed for small animal studies, we can quickly monitor and evaluate changes in response during treatment. We propose to use the model system together with small animal imaging technology to define mechanisms by which GISTs respond or become resistant to Imatinib. This involves defining specific molecules within cells that change activity after Imatinib treatment as well as testing a series of gene mutations that may be involved in drug resistance. The results of the study will help to define new targets for GIST treatment as well as validate the imaging strategy that may have wide application to monitoring targeted anti-cancer therapies.Read moreRead less
