Abstract:

Osteoporosis (OP) is a common disease in the elderly, which is characterized by decreased bone strength, decreased bone mineral density and increased risk of fracture. It is mainly caused by the imbalance of bone remodeling, that is, bone resorption caused by osteoclasts exceeds bone synthesis. Ferroptosis is an iron-dependent regulatory cell death mode caused by lipid peroxidation. Intracellular divalent iron ions (Fe2+) produce a large number of iron-dependent reactive oxygen species through REDOX reactions, which promote lipid peroxidation and lead to cell death. At present, the role and detailed mechanism of ferroptosis in the development of OP have not been fully elucidated. Ferroptosis may be mediated by glutathione peroxidase 4(GPX4), iron overload and lipid peroxidation affect osteoblasts and osteoclasts to accelerate the progression of OP. Based on the theory of ferroptosis, this review further discusses the role of ferroptosis in the development of OP and potential therapeutic targets, in order to provide new strategies and directions for the diagnosis and treatment of OP and drug research and development.

Key words: Ferroptosis, Osteoporosis, Osteoblasts, Osteoclasts
