Iron-Related Metabolic Targets in the Treatment of Osteosarcoma: Research Progress and Prospects

Area of Science:

• Oncology
• Biochemistry
• Cancer Biology

Background:

• Iron metabolism is a key regulator in cancer, with dysregulation linked to tumor initiation, progression, and resistance.
• Osteosarcoma (OS), a common bone cancer in young adults, exhibits significant iron dysregulation at cellular and microenvironmental levels.
• Current OS treatments have stagnated survival rates, necessitating novel therapeutic approaches.

Purpose of the Study:

• To provide an integrated overview of iron's role in osteosarcoma pathogenesis.
• To dissect emerging therapeutic strategies targeting iron regulatory networks in OS.
• To highlight innovative delivery platforms, such as nanomedicine, for iron-targeted therapies.

Main Methods:

• Review of current literature on iron metabolism in osteosarcoma.
• Analysis of preclinical data on iron-targeting strategies (chelation, receptor inhibition, ferroptosis, ferritinophagy).
• Integration of insights into OS molecular complexity and nanomedicine delivery.

Main Results:

• Osteosarcoma exhibits increased iron uptake, disrupted storage/export, and reliance on iron-dependent pathways promoting proliferation, metastasis, and immune evasion.
• Preclinical studies show efficacy for iron chelation, transferrin receptor inhibition, ferroptosis induction, and ferritinophagy modulation.
• Nanomedicine platforms show potential for targeted delivery of iron-modulating agents.

Conclusions:

• Iron metabolism plays a multifaceted role in osteosarcoma, offering a promising therapeutic target.
• Disrupting iron regulatory networks presents a viable strategy for novel osteosarcoma treatments.
• Further research is needed to translate these iron-targeted findings into effective clinical applications for osteosarcoma.
