Summary
Degeneration of the intervertebral disc is a painful disabling condition with major socioeconomic consequences. Medical problems associated with disc degeneration and back-pain, of sufficient severity to warrant consultation with a physician, are experienced by 90% of the population some time during their lives. In man, back pain increases in incidence in the third and fourth decades of life, peaks in the fifties and declines thereafter.

Medical problems associated with disc degeneration and back-pain, of sufficient severity to warrant consultation with a physician, are experienced by 90% of the population some time during their lives. In man, back pain increases in incidence in the third and fourth decades of life, peaks in the fifties and declines thereafter. Changes in population demographics indicate this problem will increase in severity over the next few decades. American Bureau of Census data indicate that between 1990 to 2010 the number of people >45 years will increase from 82 to 124 million, the number of elderly in emerging countries will also increase between 200 to 400% in the next 30 years. In the United States, back-pain is the second most common reason that people visit a physician and medical conditions related to back-pain account for more hospitalisations than any other musculoskeletal disorder. Despite its high incidence, associated problems of incapacity and economic implications, costed at $100 million per annum in Australia in 1992, and US$100 billion globally in 1999-2000 (Dorland Data Networks, PA, USA) the causes of low back-pain are still poorly understood. Disc disease is responsible for 23-40% of all cases of low back-pain. The management of discogenic low back-pain is currently empirical, directed either toward life-style changes to minimise symptomatology or to surgical resection or spinal arthrodesis to restrict articulation. Based on our recent findings and those of colleagues over the last 16 years, it is our strong conviction that it should be possible with a better understanding of disease mechanisms and with the use of modern technologies to inhibit, reverse or ideally prevent disc degeneration. Without such basic research there will be no scientific foundation upon which prospective therapies may be based.Read moreRead less
Proteomics Of Arthritis: Exploring Mechanisms Of Cartilage Degradation And Biomarker Identification

Summary
Arthritis is a major clinical and socio-economic problem. Arthritis involves the destruction of cartilage in joints. However, the mechanisms of initiation and progression of cartilage destruction remain poorly understood. Our studies will use new proteomic approaches to identify the changes in protein synthesis and degradation in mouse models of arthritis. This will provide critical information on disease mechanisms and for the development of diagnostic biomarkers and therapeutic approaches
Bone-specific Sclerostin And SIBLING Proteins In Osteoarthritis: Novel Contributions To Cartilage And Bone Pathology

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.
Novel Pathways Involving APC And PAR-2 In Cartilage Degradation In Osteoarthritis

Summary
Loss of the cartilage that normally lines the ends of bones is central to joint failure in arthritis and the need for replacement surgery. There are presently no treatments that stop cartilage breakdown in joint disease. This project investigates the role of a new pathway not previously thought to be active in cartilage, in the progressive damage seen in arthritis. Successful completion of these studies may provide a novel new strategy to treat joint disease.

This project addresses the National Research Priority of Promoting and Maintaining Good Health and specifically the Priority Goal of Ageing well, ageing productively. Osteoarthritis, the most common cartilage-related disease, affects nearly 1.4 million Australians, resulting in 2 in 1000 Australians undergoing total joint replacement, annually. The incidence and impact of cartilage damage on the Australian health and economy is expected to increase with the ageing population. This work leads to the development of a novel cartilage engineering technology platform that addresses Frontier Technologies and will thus provide the foundation for translation of this technology to the international marketplace.
