Abstract:
Ferroptosis, a distinct form of programmed cell death characterized by iron-dependent lipid peroxidation, has emerged as a critical factor in the pathogenesis of various diseases. Given the increasing prevalence of osteoporosis worldwide and the increasing incidence of osteoporosis, understanding the molecular mechanisms underlying bone loss is imperative for developing targeted therapies. Recent evidence suggests that ferroptosis plays a pivotal role in osteoporosis by influencing the balance between osteoblast and osteoclast activity. This review examines the mechanistic basis of ferroptosis and its pathological implications in osteoporosis. By delineating the interplay between ferroptosis and skeletal remodeling, we highlight potential therapeutic strategies aimed at modulating ferroptosis to mitigate osteoporosis progression.
Insights
Ferroptosis, a cell death process, is increasingly linked to osteoporosis. Targeting ferroptosis may offer new therapies for bone loss by balancing bone-forming and bone-resorbing cells.
Area of Science:
- Biomedicine
- Cell Biology
- Pathology
Background:
- Osteoporosis is a growing global health concern, necessitating a deeper understanding of bone loss mechanisms.
- Ferroptosis, a regulated cell death pathway involving iron and lipid peroxidation, is implicated in various diseases.
- Emerging evidence points to ferroptosis's role in disrupting the balance between osteoblasts and osteoclasts, key regulators of bone remodeling.
Purpose of the Study:
- To review the mechanistic underpinnings of ferroptosis.
- To explore the pathological role of ferroptosis in osteoporosis.
- To identify potential therapeutic strategies targeting ferroptosis for osteoporosis treatment.
Main Methods:
- Literature review of ferroptosis mechanisms.
- Analysis of studies linking ferroptosis to bone metabolism.
- Synthesis of current research on ferroptosis and osteoporosis.
Main Results:
- Ferroptosis influences osteoblast and osteoclast differentiation and function.
- Iron accumulation and lipid peroxidation are key events in ferroptosis-induced bone loss.
- Dysregulation of ferroptosis contributes to the pathogenesis of osteoporosis.
Conclusions:
- Ferroptosis is a significant contributor to osteoporosis.
- Modulating ferroptosis presents a promising therapeutic avenue for osteoporosis.
- Further research into ferroptosis pathways could reveal novel treatment targets.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
