Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy. Researchers have now identified Atf4 as the regulatory gene that ...

Bone tissue homeostasis is maintained by a balance between bone formation by osteoblasts and bone resorption by osteoclasts. However, when osteoblast function declines with age, bone remodeling ...

Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy via secretion of the molecule osteocalcin. Gerard Karsenty and ...
