Brief description Excessive bone resorption has been observed in many common bone diseases such as osteoporosis, Paget's disease and arthritis. These are major health problems in Australia and other developed countries. Increased activation or formation of osteoclasts is responsible for the excessive bone resorption. Understanding the mechanisms by which the osteoclasts exert its function and activation is an important step toward developing strategies to combat excessive bone resorption for the treatment and prevention of osteolytic disorders. This project attempts to address the important and fundamental issue of osteoclast function. We have identified caltrin, a known calcium transport inhibitor, that is likely to be biologically important in osteoclast calcium homeostasis. This project intends to investigate the role of caltrin in calcium-induced apoptosis, osteoclast bone resorption and the cellular and molecular mechanisms underlined. It will enhance our knowledge of calcium regulation in osteoclasts and provide information to facilitate the development of new anti-resorptive agents.
