Summary
Osteoclasts are directly related to many lytic bone disorders including osteoporosis, osteoarthritis and Paget's diseases. Development of strategies to control the formation or activities of osteoclasts has been a major focus of bone research. The vacuolar proton pump (V-ATPase) located on the plasma membrane of the osteoclast is responsible for creating a low pH environment critical for bone resorption, and therefore a potential molecular target for the discovery of novel bone antiresorptive ag ....Osteoclasts are directly related to many lytic bone disorders including osteoporosis, osteoarthritis and Paget's diseases. Development of strategies to control the formation or activities of osteoclasts has been a major focus of bone research. The vacuolar proton pump (V-ATPase) located on the plasma membrane of the osteoclast is responsible for creating a low pH environment critical for bone resorption, and therefore a potential molecular target for the discovery of novel bone antiresorptive agents useful for the treatment of lytic bone disorders. The proposed research will give considerable insight into the role of the both V-ATPase accessory subunit Ac45 and V-ATPase complex in osteoclasts. Understanding the molecular and cellular mechanisms by which V-ATPases regulate osteoclast bone resorption will facilitate the development of novel and selective inhibitors for the treatment of lytic bone disorders.Read moreRead less
