Osteal Macrophages: Novel Regulators Of Osteoblast Function And The Endosteal Stem Cell Niche

Summary
Bone diseases are a major health problem and current treatments are inadequate. We are investigating a novel role for macrophages (cells important in tissue maintenance and immune responses) in bone growth, repair and disease. Greater understanding of this will provide new ways to treat bone disease. We will also determine if these macrophages help support stem cells that reside near bone surfaces, which may provide new treatment strategies to improve bone marrow transplantation in cancer.
Acute Lymphoblastic Leukemia And The Bone Marrow Microenvironment

Summary
This research aims to identify new drugs for the treatment of childhood and adult acute lymphoblastic leukemia (ALL). We have identified drugs that interfere with interactions between the bone marrow and leukemic cells and hypothesise that these will increase the potency of currently used chemotherapy. We will test these agents in animal models of human leukemia. By analysing the effects of these new drugs we will also understand how we can further improve treatments.
Characterisation And Therapeutic Targeting Of Molecular Pathways That Promote Breast Cancer Metastasis To Bone

Summary
Breast cancer that has spread to bone cannot be cured. Using the most clinically relevant model of breast cancer available we have identified that tumour cells growing in bone need to suppress immune elimination (by suppressing the Type I interferons) and invade through the bone tissue (by activation of cysteine cathepsins). Studying the functional role of these pathways will provide novel insight into the mechanisms of breast cancer spread to bone that can be augmented therapeutically.
Psychiatric Disorders, Psychotropic Agents And Bone Health: From Benchtop To Bedside.

Summary
Just under half of all people with a psychiatric disorder have a chronic physical illness. One common and neglected comorbidity is osteoporosis. Dr Williams has brought together a multi-disciplinary team of researchers and clinicians that are gathering laboratory through to clinical evidence regarding the interplay between psychiatric disorders, the medication used to treat these disorders and bone health with the aim of informing clinical practice and guiding clinical choice.
New Approaches To The Prevention And Treatment Of Musculoskeletal Disease

Summary
In Australia, musculoskeletal conditions like osteoarthritis and back pain are responsible for much pain and disability. Although until recently these were considered to be purely due to wear and tear, Associate Professor Wluka, a rheumatologist, has shown that these are not simply due to overuse and loading but metabolic factors also play a role. This award will enable the role of these factors to be examined and new therapies tested in clinical trials, providing evidence to improve the managem ....In Australia, musculoskeletal conditions like osteoarthritis and back pain are responsible for much pain and disability.

Manipulation Of Haematopoietic Stem Cell Niches To Improve Therapeutic Outcomes

Summary
My aim is to understand how stem cells are naturally regulated by the body. My central hypothesis is that local environment (niche) factors largely govern stem cell behaviour. Identification and manipulation of these factors will offer a novel therapeutic opportunity to improve the clinical use of normal haematopoietic stem cells to improve transplantation success, as well as sensitise leukaemia cells to chemotherapy.
Mechanisms Underlying The Effects Of Retinoic Acid Receptor Gamma In Haemopoiesis And Bone Homeostasis

Summary
My recent studies have demonstrated that a model of vitamin A deficiency results in impaired blood cell production and contributes to a blood cell disorder that can progress to leukaemia. There are also reduced numbers of blood stem cells (which give rise to all blood cells) and bone (which helps to regulate blood cell production) in this mouse model. In these studies I seek to understand more on how vitamin A deficiency causes these defects, which may lead to better treatment of such diseases.
Autocrine Vitamin D Metabolism, Activity And Bone Health
Funder

Funding Amount
$459,270.00
Summary
This project will provide the detailed understanding of the activities of vitamin D within the bone microenvironment and offers the exciting prospect of elucidating the mechanistic reasons for maintaining an adequate vitamin D status in relation to the prevention of osteoporotic hip fractures. Thus, this project has great potential to improve community health by being able to recommend vitamin D supplementation made on the basis of maintaining normal bone cell function.
