Recent progress on targeting ferroptosis for cancer therapy

Area of Science:

• Biochemistry
• Cell Biology
• Oncology

Background:

• Ferroptosis is a distinct mode of cell death characterized by iron-mediated lipid peroxidation and reactive oxygen species (ROS) accumulation.
• Unlike other cell death types (necrosis, apoptosis, autophagy, pyroptosis), ferroptosis has unique cellular, molecular, and genetic signatures.
• Ferroptosis has emerged as a significant target for novel antitumor therapies.

Purpose of the Study:

• To provide a comprehensive overview of ferroptosis mechanisms regulating cancer cell sensitivity.
• To review research progress on ferroptosis-related drugs, including western medicine, traditional Chinese medicine, and nanomedicine.
• To explore the intricate relationship between ferroptosis and cancer treatment, drug resistance, and antitumor immunotherapy.

Main Methods:

• Literature review of ferroptosis mechanisms.
• Analysis of research on ferroptosis-inducing agents.
• Synthesis of information on ferroptosis in cancer therapy, resistance, and immunotherapy.

Main Results:

• Detailed mechanisms governing cancer cell ferroptosis sensitivity are elucidated.
• Current advancements in ferroptosis-targeting drugs across various modalities are presented.
• The multifaceted role of ferroptosis in cancer treatment, overcoming drug resistance, and enhancing immunotherapy is discussed.

Conclusions:

• Ferroptosis represents a critical area of research with substantial potential for cancer therapy development.
• Understanding ferroptosis mechanisms and drug development is key to improving cancer treatment outcomes.
• Ferroptosis holds promise for synergistic effects with existing cancer therapies, including immunotherapy.
