Summary
microRNAs are newly discovered chemicals that were the subject of the 2006 Nobel Prize in Medicine. These chemicals decrease the amount of specific molecular ‘targets’ in cells, and play an important role in cancer. Currently we do not understand how these chemicals choose their targets, and we propose to use a computer-based approach to discover how they affect genes in cancer. This will improve our understanding of cancer and thereby lead to the discovery of novel anti-cancer therapies.

Summary
Our genome encodes ~25,000 genes that shape out an individual from head to toe. Malfunction of a particular gene could cause fatal health problem or disease. Nonetheless, the mis-regulation of functioning genes can also result in serious diseases. In this study, we are going to use large-scale gene regulation information and advanced computing techniques to clarify the regulation network of human genome on a global level. Hence, helping us to understand more about diseases of gene transcription.

Summary
The MYB gene is essential for both normal blood cell formation and the growth of leukaemia cells. It acts by switching other genes (target genes) on and off. This project aims to advance our understanding of how MYB functions, by carrying out a comprehensive search for MYB target genes. In particular it will focus on target genes that help explain MYB's ability to control cellular growth and maturation. Some of these target genes may provide leads for future anti-cancer drug development.
Macrophages are a key component of the immune system; thier functions include killing of pathogens as well as cancerous cells. Macrophage lineage cells are derived from stem cells within the bone marrow and thier differentiation, proliferation and survival is mediated by a particular growth factor termed colony stimulating factor-1 (CSF-1). The understanding of how macrophage lineage cells develop will help us to treat many diseases including certain cancers (such as leukemia), arthritis and inf ....Macrophages are a key component of the immune system; thier functions include killing of pathogens as well as cancerous cells. Macrophage lineage cells are derived from stem cells within the bone marrow and thier differentiation, proliferation and survival is mediated by a particular growth factor termed colony stimulating factor-1 (CSF-1). The understanding of how macrophage lineage cells develop will help us to treat many diseases including certain cancers (such as leukemia), arthritis and inflammation, and disorders of the immune system. The action of CSF-1 is mediated by the CSF-1 receptor (CSF-1R) which, when activated, controls gene regulation. In this proposal we will study CSF-1R activation and identify the genes regulated by CSF-1 with a view to characterize genes critical for macrophage development. These genes may provide potential targets for new pharmacological agents.Read moreRead less

Summary
Using DNA based technologies we have focused on rare white blood cells known as regulatory T cells. These cells are policeman of the immune system and are responsible for maintaining balanced immune reactions, and preventing attack against harmless substances. These cells prevent autoimmune disease in healthy individuals, and only by first understanding how they work normally can we investigate and correct the defects in autoimmune diseases such as type 1 diabetes.

Summary
In virtually all cases, death from solid tumors (including breast cancer) results from invasion and metastasis. The exciting recent pre-clinical observations that a new class of anticancer agents (which primarily target tumour invasion and metastasis) operate synergistically with a number of standard chemotherapy cytotoxics (such as those already used to treat breast cancer) suggests a new and significant additional therapeutic potential for both agents. The basis of this synergism is completely ....In virtually all cases, death from solid tumors (including breast cancer) results from invasion and metastasis. The exciting recent pre-clinical observations that a new class of anticancer agents (which primarily target tumour invasion and metastasis) operate synergistically with a number of standard chemotherapy cytotoxics (such as those already used to treat breast cancer) suggests a new and significant additional therapeutic potential for both agents. The basis of this synergism is completely unknown however, and it is our contention that this mechanism needs to be explored at the molecular level in order to identify which combinations will have most potential in the clinic. This proposal aims to characterize synergistic combinations in an animal model of breast cancer progression, and to determine the specific molecular mechanism of the process. Each phase of the proposed study is a worthwhile undertaking in itself, and while it makes primary use of a breast cancer growth and metastasis system, the information revealed should be relevant to many tumour types. This information can be used to formulate new therapeutic strategies for the treatment of solid tumours and their metastasis in patients.Read moreRead less
