Summary
Acute leukemia is a devastating cancer arising from primitive cells in the bone marrow called stem cells. We have identified a protein (PRMT5) that is highly expressed in leukemia stem cells. Our preliminary experiments suggest that blocking the function of this protein with a novel drug can stop the growth of these cells. This project will use a variety of mouse models of acute leukemia to determine how PRMT5 keeps stem cells alive and whether this drug will be a valuable new treatment.

Summary
At present, treatment of leukaemia is based either on established chemotherapeutic drug treatment or newly identified inhibitor drugs currently being tested as part of clinical trials. Both these treatments are known to induce or select for resistance to the drugs in some cases. Resistance usually reduces the success rate of any further treatment with the same or similar drugs. To discover possible ways of overcoming drug resistance it is important to understand the mechanisms that are responsib ....At present, treatment of leukaemia is based either on established chemotherapeutic drug treatment or newly identified inhibitor drugs currently being tested as part of clinical trials. Both these treatments are known to induce or select for resistance to the drugs in some cases. Resistance usually reduces the success rate of any further treatment with the same or similar drugs. To discover possible ways of overcoming drug resistance it is important to understand the mechanisms that are responsible. To date a number of mechanisms that cause resistance are known, but there are still unidentified mechanisms that are associated with drug resistance. The aim of our work is to use a new method to identify unknown drug resistance mechanisms in leukaemia. Once a mechanism is identified, we will determine its relevance in leukaemia by screening a number of patients that have shown resistance to treatment. If identified as a common mechanism of resistance in leukaemic patients, we will test possible agents able to prevent drug resistance that could be used in conjunction with drug during treatment, and to screen new drugs for susceptibility to resistance mechanisms. Diagnostic tests to detect the presence of the known resistance mechanisms prior to treatment could be used in selection of the most appropriate drug combinations for individual patients. Some of the known drug resistance mechanisms that occur in leukaemia are also operative in other forms of cancer and the project is of general relevance to cancer chemotherapy.Read moreRead less
