Osteoporosis is a disorder in which there is a net bone loss and microarchitectural deterioration with an increased risk of bone fracture because of uncoupling of bone formation and bone resorption. The treatment of osteoporosis aims to inhibit bone resorption by osteoclasts and/or promote bone formation by osteoblasts. However, most of the current approaches for treating osteoporosis focus on inhibiting bone resorption. As the only US FDA-approved anabolic agent, the recombinant human parathyroid hormone is recommended for consecutive 2-year period treatment in a clinical setting. Therefore, it is highly desirable to identify novel bone anabolic agents or approaches for osteoporosis treatment. In this review, the authors introduce a new bone anabolic therapy by means of RNAi strategy. Specifically, the authors also discuss the current status and perspectives for RNAi as a novel anabolic approach in the treatment of osteoporosis.
