Summary
Arthritis is a major clinical problem and involves the destruction of cartilage in joints. However, the mechanisms of how this cartilage destruction is initiated and progresses remain poorly understood. We recently discovered that that three proteins that play a role in bone are also produced in cartilage and are increased in cartilage during osteoarthritis. We will determine the role of each of these in the disease mechanism to provide new therapeutic and biomarker targets.
EFFECT OF LIPOXIN A4 AND PROSTAGLANDIN E2 IN ASSISSTED BONE HEALING

Summary
Bone healing and repair following trauma involves a complex series of events at both the cellular and molecular levels. This study aims to determine that local application of optimal dose of lipoxin A4 (promote resolution of inflammation) and prostaglandin E2 (low dosage stimulating localised bone formation) will promote healing following the placement of polymer foam in the defect, there by develop a therapy where bone deposition is accelerated and healing is enhanced.
Smart Synthetic Biomaterial Provides An Appropriate Microenvironment For Bone Tissue Regeneration

Summary
The demand for synthetic biomaterials to repair lost or diseased bone is rapidly growing and placing a major burden on national health budgets. But the synthetic scaffolds currently in use are far from optimal. My aim is to determine the underlying mechanisms by which synthetic biomaterials promote bone regeneration, in order to develop better scaffolds. This would improve health outcomes for recipients of bone graft substitutes as well as reduce individual and national healthcare costs.
Chondrocyte Hypertrophy In Development And Disease

Summary
Whereas chondrocyte hypertrophy is a normal feature of skeletal growth, in adult chondrocytes it is associated with osteoarthritis (OA). We propose that collagen II fragments provide signals for hypertrophy in cartilage. The lack of collagen II fragments in our collagenase-resistant mouse provides a unique opportunity to address the role of collagen II fragments in driving cellular hypertrophy. We will identify bioactive collagen II fragments that represent novel targets for OA therapies
Monitoring Bone Loss And Response To Therapy Through Bone Material And Structural Composition

Summary
Millions of scripts are filled for treatment of osteoporosis. However, there is no way of knowing if these drugs are right for these individuals, if it improves bone strength or are actually doing harm. Bone density measurement is of limited value. We have developed a new analysis method that measures changes in bone structure that tell us if the treatment is or is not working so alternative treatment can be used. The aim of this study is to test this new method.
Identification Of Novel PTH Anabolic Targets In Osteoblasts

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.
