Mature red cells develop from hemopoietic stem cells in the adult bone marrow. The production of red blood cells is primarily controlled by the hormone erythropoietin (Epo). Previously we had identified that the protein Lyn must be present inside primitive red blood cells for Epo to stimulate them to become mature functional cells. We will determine the role of several molecules that interact with Lyn including Cbp, Liar and LACM, towards apects of red blood cell development.

Summary
Multiple myeloma is an incurable disease of the antibody-producing B cell. Patients with MM, nearly always present with bone pain and unexplained bone fractures. These fractures are caused by the cancerous MM B cells, which are found in large numbers in discrete pockets throughout the bone marrow, close to the inner bone surface. The way that the cancerous B cells cause the local bone lesions is thought to be through the heightened activation of recruitment of osteoclasts.

These fractures are caused by the cancerous MM B cells, which are found in large numbers in discrete pockets throughout the bone marrow, close to the inner bone surface. The way that the cancerous B cells cause the local bone lesions is thought to be through the heightened activation of recruitment of osteoclasts. Osteoclasts are cells which normally, in a controlled manner, resorb bone as part of the ongoing process of new bone formation. We propose that myeloma cells, which exhibit characteristics of osteoclasts, home to sites in the bone marrow and initiate this bone breakdown and furthermore secrete factors required for osteoclast maturation and activity. We believe that these molecules include the recently defined molecule, termed osteoclast differentiation factor, which is normally produced by bone-producing cells known as osteoblasts. Moreover, we feel that myeloma B cells alter the function of osteoblast cells, which results in a decrease in bone formation. Finally, we propose that this disease and its associated bone defects originate from changes in the expression of a number of genes. The results from theses studies should provide a greater understanding of the way in which this B cell cancer originates and how it causes bone defects. This will lead to the development of better treatments to improve the survival of patients with MM, and will lead to therapies to prevent the associated bone complications.Read moreRead less

Summary
Mammalian cells contain a complex switchboard, which directs the cell to grow, die, multiply or move in response to external cues. When communication breaks down within the cell, diseases arise. Our studies are directed towards identifying the molecules that comprise the switchboard which directs blood cell formation. A detailed understanding of the regulators of blood cell formation will equip us with a sound starting point for designing drugs to ameliorate blood diseases.

Summary
Novel immune-based treatments for advanced, incurable, cancer have significantly improved patient survival. Although these treatments have proven highly effective, they are associated with the unpredictable development of severe and sometimes life-threatening autoimmune disease. We aim to discover ways to predict and potentially prevent these complications by identifying genetic risk factors and markers in blood samples. If successful, this will be a ground breaking advance in cancer care.
Patient Tailored Anti-tumour T Cells To Prevent Relapse In Patients With Acute Myeloid Leukaemia Undergoing Allogeneic Haemopoietic Stem Cell Transplantation

Summary
Acute myeloid leukaemia (AML) is the most common acute leukaemia in adults. Patients with high-risk AML have a 2-year survival of less than 20%. Blood or bone marrow transplant from a healthy donor is often the only chance of cure but the leukaemia frequently returns. Dr Blyth will perform a clinical trial giving leukaemia fighting immune cells from the transplant donor to patients with high risk AML to prevent relapse after transplant.

Summary
Most people with leukaemia and lymphoma who relapse early after chemotherapy die of their disease. Inserting special genes into immune cells can enable them to kill leukaemia and lymphoma and has led to dramatic cures, but the cost of the viral vectors used to make these cells is prohibitively expensive. We will make leukaemia and lymphoma specific immune cells from patients using an inexpensive non-viral system, then administer the immune cells to patients to assess their safety and efficacy.

Arguably, the laboratory heads within our division and our collaborators from the Structure Biology Division at WEHI constitute the world’s strongest group with this focus. Our accumulated experience in this field from its renaissance in 1988 and the many unique materials they have created superbly position us to answer the fundamental questions and translate them into new therapeutic approaches. Our team’s second focus, the links of stem cells to cancer, is also of great importance, because the rare stem cells in the tumour may dictate therapeutic outcome. This Fellowship aims to addresses fundamental issues with enormous potential for medicine. It builds on productive ongoing research by a team with diverse complementary expertise, a record of effective interaction, high momentum and a history of path-breaking discoveries. I plan to maintain and further develop our Division (the Molecular Genetics of Cancer Division at WEHI) as one of the strongest teams for cancer research and development of cancer therapies in the world. Our division contains several laboratories that are highly interactive and complimentary in their approaches and research interests. I plan to strengthen the already highly productive laboratories in our division and to develop some new ones (see below under ‘proposed team’). I plan to increase work of our division to also include studies on other solid tumours (e.g. colon cancer, lung cancer, prostate cancer). This Fellowships aims to greatly enhance cancer research and hopefully also clinical practice in Australia. This should enhance the reputation of Australia as a country with recognized excellence in medical research and clinical practice. I am also confident that our division will continue to educate outstanding PhD graduates and postdoctoral fellows who will in due course become independent researchers and develop into future leaders in medical research in Australia and-or overseas.Read moreRead less
