title: [Role of OPG in calcium metabolism].
abstract: Osteoprotegerin is a newly identified circulating factor that inhibits osteoclast differentiation and maturation. Molecular mechanisms for bone resorption have been becoming clear. Serum levels of OPG were examined in several clinical conditions. Furthermore, it has recently been suggested that OPG might play substantial roles in vascular calcification.
