Inhibition of Osteoblastic Bone Formation by Nuclear Factor-kappaB
An imbalance in bone formation relative to bone resorption results in the net bone loss that occurs in osteoporosis and inflammatory bone diseases. Although it is well known how bone resorption is stimulated, the molecular mechanisms that mediate impaired bone formation are poorly understood.
