Ferroptosis - A new target of osteoporosis.

Osteoporosis is a bone metabolic disease characterized by reduced bone mass and deterioration of bone tissue microarchitecture, leading to enhanced skeletal fragility and susceptibility to fracture. Unbalanced bone remodeling is the primary pathogenetic factor of osteoporosis, in which osteoclast-mediated bone resorption exceeds osteoblast-mediated bone formation. Bisphosphonates and calcitonin are among the drugs commonly used to treat osteoporosis, in addition to the bone nutrients vitamin D and calcium supplements.
