Summary
Hip replacements often fail due to the loss of adjacent bone. Metal or polyethylene particles are produced as the prosthesis bearing surface wears but how do these particles lead to bone loss? Our work suggests involvement of osteocytes within the bone mineral, which are increasingly understood to drive bone physiology and pathology. We will explore the role of the osteocytes by examining their response to particles, which may identify a new target to prevent particle-induced bone loss.
Targeting Bone Marrow Lesions To Find Interventions In The Progression Of Osteoarthritis

Summary
It is essential to elucidate the underlying cause(s) of osteoarthritis because our current level of understanding of this condition has failed to produce effective treatments. Lesions in the bone under the cartilage (BMLs), seen using MRI, have strong potential value for the objective monitoring and management of OA. However, because the nature of BMLs is not well understood, the aim of this application is to perform a comprehensive study of BMLs in OA bone.
Whole Body Vibration For Osteoporosis: Shaking Up Our Treatment Options

Summary
Our aim is to examine the ability of vibration alone and in combination with osteoporosis drugs to reduce hip fracture in postmenopausal women. In Australia, 1 in 2 women >60yrs, will sustain an osteoporotic fracture. Only drugs notably decrease fracture; however none are entirely effective and some patients don’t respond. Whole body vibration has emerged as a potentially effective therapy. A combination of vibration and drugs may enhance the effects of both and revolutionise treatment.
Targeting Bone Marrow Mediated Angiogenesis And Metastasis In Breast Cancer

Summary
Despite advances in treatment and diagnostics breast cancer (BC) remains one of the leading causes of death in women. Metastases and tumour blood vessel recruitment are linked. Work by Dr Mellick and others has shown that host bone marrow contributes endothelial progenitor cells (EPCs) to tumour vasculature. The chemokines and their receptors, which differentiate EPCs from tumour vessels, will be knocked down in the tumour cells and EPC progenitors with the aim of preventing tumour spread.
