Summary
PML is a vital tumour suppressor, but little is known about its regulation. We established that PML levels are affected by another cellular protein E6AP. This study will define the mechanism by which E6AP influences PML. Human cancers will be screened for the involvement of these proteins, to gain new insights into cancer onset. The intended practical outcome of these studies is to aid cancer diagnosis and provide new anti-cancer drugs.

Summary
The most important agent of the body for fighting cancer is the cellular protein p53. In more than 50% of all human cancers, it looses its anticancer properties through mutation. In an insidious manner this new mutant form then acts to promote cancer. To better treat cancer we need to understand how mutant p53 functions. We will study how it interacts with its molecular partners in cancer cells.
Breast cancer affects approximately one in ten women and is therefore a major health problem. In order to improve the diagnosis, treatment and prognosis of this disease, it is critical to understand the molecular defects which contribute to disease initiation and progression. Over the last twenty years significant progress has been made in this regard, however there still remain a considerable number of unanswered questions. For example, it is not yet clear which are the most critical molecules ....Breast cancer affects approximately one in ten women and is therefore a major health problem. In order to improve the diagnosis, treatment and prognosis of this disease, it is critical to understand the molecular defects which contribute to disease initiation and progression. Over the last twenty years significant progress has been made in this regard, however there still remain a considerable number of unanswered questions. For example, it is not yet clear which are the most critical molecules contributing to this disease and thus which are the best targets for therapeutic intervention. In this proposal, we aim to study two molecules. The first is called BRCA1 and is particularly important in inherited susceptibility to breast cancer. The second is called PML and, although originally described as a leukaemia-associated gene, it has since been implicated in a number of cancers. Specifically, we aim to investigate the possibility that PML and BRCA1 work together to protect against cancer and that they do this by regulating the ends of chromosomes, that is, the telomeres.Read moreRead less
