Deficiency of PDK1 in osteoclasts delays fracture healing and repair.

ABSTRACT: Bone fractures are common traumatic injuries of the musculoskeletal system. However, delayed union and non‑union fractures are a major clinical problem that present significant socioeconomic burden to patients and the public health sector. The bone‑resorbing osteoclasts and bone‑forming osteoblasts serve important roles in the fracture repair/healing process. Osteoclast deficiency or decreased osteoblast activity negatively impacts fracture healing. We previously demonstrated that the specific deletion of the serine/threonine kinase 3‑phosphoinositide‑dependent protein kinase 1 (PDK1) in osteoclasts leads to abrogated osteoclast formation and bone resorption in response to receptor activator of nuclear factor‑κB in vitro and protected mice against ovariectomized‑induced bone loss and lipop
