Summary
Hydatid disease is a zoonosis caused by the dog tapeworm Echinococcus with millions of people-animals infected. After decades of study, effective treatment remains a major challenge. We will use a combination of recently developed techniques to isolate specific genes associated with Echinococcus differentiation. Understanding how these genes are controlled will increase our sparse knowledge of the developmental biology of this important parasite and provide new clues for more effective therapies

Summary
Cancer development is associated with changes in the genetic composition of the cell. These changes involve the loss/gain of genetic material and/or changes in gene expression. Using sophisticated technology, we will define the changes in the genes that are associated with the transition from a benign to a malignant cancer state. We will examine this process in the blood cancer, multiple myeloma, in order to identify new treatment targets for this incurable disease.
Primary central nervous system (CNS) tumours, arising in the brain and spinal cord, are the leading cause of cancer-related deaths in children less than 15 years of age. Medulloblastomas and other primitive neuroectodermal tumours (PNETs) are the most common form of primary childhood brain tumours, accounting for 25-30% of cases. Despite notable recent advances in our understanding of the molecular genetic basis of malignancies, the pathogenesis of CNS PNETs remains obscure.

Medulloblastomas and other primitive neuroectodermal tumours (PNETs) are the most common form of primary childhood brain tumours, accounting for 25-30% of cases. Despite notable recent advances in our understanding of the molecular genetic basis of malignancies, the pathogenesis of CNS PNETs remains obscure. To address this problem, we propose to apply a novel combinatorial approach for the identification of PNET tumour suppressor genes utilising both representational difference analysis (RDA) and microarray expression profiling. Data from this study will help to elucidate the molecular pathways that are compromised in the initiation and growth of PNETs. This information will have direct implications for the development of improved diagnostic and prognostic indicators necessary for the design of more effective therapeutic strategies for the treatment of PNET patients.Read moreRead less

Summary
Cancer is fundamentally a genetic disease that arises when errors (mutations) accumulate in genes involved in regulating how and when cells grow. An important class of gene involved in this process are the tumour suppressors whose primary function is to inhibit cell growth. It is widely believed that significant improvements in the treatment and diagnosis of cancer will only be achievable once we have a detailed understanding of how these genes work. It is likely that dozens of tumour suppressor ....Cancer is fundamentally a genetic disease that arises when errors (mutations) accumulate in genes involved in regulating how and when cells grow. An important class of gene involved in this process are the tumour suppressors whose primary function is to inhibit cell growth. It is widely believed that significant improvements in the treatment and diagnosis of cancer will only be achievable once we have a detailed understanding of how these genes work. It is likely that dozens of tumour suppressor genes exist in the human genome and of these only a small proportion have been identified. The aim of this study is to identify genes on human chromosome 22 that are involved in the development of breast and ovarian cancer. Genetic evidence from many investigators, including data from our own laboratory, has indicated that multiple tumour suppressor genes are present on human chromosome 22 but as yet none have been positively identified. Part of the difficulty in identifying these genes is that cancer cells often have a lot of genetic damage and it is hard to distinguish the important changes from background genetic noise'. To circumvent this problem we are using a functional cloning approach which identifies tumour suppressor genes by their ability to inhibit the growth of cancers cells grown in culture in the laboratory. Genes that are identified in this way will be evaluated for the presence of genetic mutations in real human cancers which will give us a better idea of their true significance in tumour development. In addition to enhancing our understanding of the process tumour development this project may identify new targets for anti-cancer therapies.Read moreRead less
