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.
Tendon injury is one of the most common health problems worldwide and affects almost everyone at some point in particular the aging populaiton. However, the current treatments are not well defined. We identifed an extracellular molecules SPARC that potentially plays an important role in tendon function. The aim of this study is to examine the role of SPARC in tendon development, homestasis and degenerative using transgenic mice and gene therapy. We predict that SPARC will have therapeutic value ....Tendon injury is one of the most common health problems worldwide and affects almost everyone at some point in particular the aging populaiton.

Summary
Osteoporosis treatments prevent fractures by hindering cells that erode the skeleton. Normally, those cells also repair injuries like stress fractures. Some patients, treated for long periods, can suffer fractures because the treatment slows bone healing. We have an innovative model to test alternative treatments to accelerate stress fracture healing, while osteoporosis treatment continues. This could prevent unusual stress fractures, in patients who still need the bone-sparing effectiveness of ....Osteoporosis treatments prevent fractures by hindering cells that erode the skeleton.

Summary
The WNT pathway is a powerful regulator of bone cell differentiation and bone formation. Two WNT modulators, sclerostin ad Dickkopf 1, are being developed for therapy in bone disease, but critical questions remain unanswered. In this study we use unique genetic mouse models created by the applicants to resolve specific deficiencies surrounding their actions and application as therapies.
NT-3 As An Upstream And Potentially Master Regulator Promoting Bone Fracture Healing

Funding Amount

Summary
There is a strong clinical need for cost-effective treatments for delayed healing or non-union bone fractures. Our recent data suggest injury site-derived neurotrophin-3 (NT-3) may be an important overall regulator of bone repair by inducing key factors involved in fracture callus formation and remodelling. This project will address roles and mechanisms of endogenous NT-3 in bone repair and the likelihood of exogenous NT-3 protein in promoting bone healing in clinically relevant fracture models.
