Summary
Osteoporosis is a major disease affecting Australians. Whilst there are a number of drugs available that will reduce bone loss, there are few drugs available that build new bone, and little is known of the action of these drugs. New targets have been identified that modulate bone formation, and this project aims to validate these in appropriate models and determine their mechanism of action.
Optimising Bone Regeneration Using Advanced Design And Fabrication Technologies

Funding Amount
$916,671.00
Summary
The aging population has produced a rapidly increasing demand for synthetic implants that can regenerate lost or diseased bone. This project will produce an implant that represents a viable alternative to bone autografts and allografts with broad applications for the repair of large or challenging bone defects. Such an achievement will have significant healthcare benefits by reducing patient morbidity and recovery time, and improving long-term outcomes.
Novel Treatment Approaches To Prevent Joint Fusion In Ankylosing Spondylitis

Funding Amount
$477,440.00
Summary
Ankylosing spondylitis (AS) is a form of arthritis targeting the spine and pelvis that causes uncontrolled bone formation resulting in complete joint fusion, severe disability and even death for which no therapies are currently available. Using a mouse model that closely replicates the human disease we will characterise the changes causing this joint fusion and identify possible new targets to develop novel treatments.
Vitamin E-bisphosphonate Conjugates: A New Therapeutic Approach Targeting Pathological Bone Loss Associated With Osteoporosis

Funding Amount
$471,984.00
Summary
Approximately 2 million Australians have osteoporosis, a disease which increases the risk of fracture and whose monetary and social costs are large and growing. The objective of this proposal is to exploit the osteotropic properties of novel compounds of vitamin E (VE) derivatives (BPVE) conjugated to bisphosphonates (BP), which will have anti-oxidant, anti-osteolytic and bone anabolic properties, and will be taken up selectively in the skeleton for the treatment of osteoporosis.
Osteal Macrophages As Therapeutic Targets For Fracture Repair

Funding Amount
$618,015.00
Summary
Fragility fracture associated with osteoporosis is a substantial health problem costing $1.62 billion to treat in 2012 in Australia. There is no approved therapy to improve and accelerate fracture healing to help reduce this increasing health burden. This research will advance understanding of fracture repair in healthy and osteoporotic bone and progress development of a fracture therapy to improve bone repair by promoting specialised immune cells.
Identifying The Physiological Actions Of Calcitonin

Funding Amount
$683,040.00
Summary
Calcitonin is a hormone whose main action has long been regarded as the slowing down of bone breakdown, however, its importance in human physiology is unknown. The aim of this study is to understand the role of calcitonin in regulating bone formation and protecting the skeleton in times of calcium stress, such as lactation. These results will greatly advance our understanding of the control of bone and calcium homeostasis, which will have implications for the treatment of bone disorders.
RANKL, A Critical New Player In The Coordination Of Whole Body Energy Homeostasis

Summary
Imbalances in food intake and energy expenditure can lead to the development of obesity or anorexia. Conserved mechanisms are in place to coordinate the energy requirements of organs and tissues. The main centre is the brain which receives, processes and sends out information to accommodate the needs of the different tissues. Bone tissue in particular is in need of a lot of energy. Factors produced by bone are therefore critical in the coordination of whole body energy homeostasis.
Why Macrophages Promote Heterotopic Ossifications Following Spinal Cord Injuries
Funder
National Health and Medical Research Council
Funding Amount
$586,950.00
Summary
A frequent complications of brain and spine injuries is the formation of bones outside of the skeleton called "heterotopic ossifications", particularly around joints such as the knee, hip, elbow or shoulder. They grow over a few months to become so large (up to 2 kg) that they block muscles and joints, increasing pain, morbidity and dependance. This project is to understand why heterotopic ossifications form in patients with spine injuries aiming to discover effecttive treatments.
Structural And Functional Analysis Of Oncostatin M Receptor Signalling Complexes

Summary
Understanding how a chemical messenger selectively controls bone formation may lead to development of new therapies for osteoporosis and potentially other important diseases.
Development Of Vinorelbine As A Tablet Based Therapy To Cure Ectopic Pregnancies
Funder
National Health and Medical Research Council
Funding Amount
$361,594.00
Summary
Ectopic pregnancies occur if the pregnancy implants in the Fallopian tube. They can be deadly and most are treated surgically. We will examine the exciting possibility that instead of surgery, ectopic pregnancies may be cured with a tablet taken just once. We will perform laboratory studies and a clinical trial, giving vinorelbine to women with ectopic pregnancies.
