Exposure to ionizing radiation can result in bone damage, including decreased osteocyte number and suppressed osteoblastic activity. However, molecular mechanisms remain to be elucidated, and effective prevention strategies are still limited. This study was to investigate whether cerium oxide nanoparticles (CeO2 NP) can protect MC3T3-E1 osteoblast-like cells from damaging effects of X-ray irradiation, and to study the underpinning mechanism(s).
