To elucidate the regulatory networks of ferroptosis in hepatocellular carcinoma (HCC) and propose strategies to enhance sensitivity to ferroptosis.
Approach:
Regulatory Networks: The study explores three interconnected regulatory networks of ferroptosis: metabolic, epigenetic, and microenvironmental, detailing their interactions.
Closed-loop Regulatory Model: A closed-loop regulatory model integrating metabolic biomarkers, epigenetic indicators, and microenvironmental features is proposed to enhance ferroptosis sensitivity.
Clinical Translation: The article summarizes clinical translation progress, toxicity risks, and challenges associated with ferroptosis-targeted therapies, highlighting specific obstacles.
Key Findings:
Ferroptosis is characterized by lipid peroxidation and is distinct from apoptosis and necrosis.
The GSH/GPX4 axis is a central pathway inhibiting lipid peroxidation and preventing ferroptosis.
Iron metabolism plays a crucial role in ferroptosis, with ferritinophagy increasing sensitivity to ferroptosis.
Interpretation:
The study provides a comprehensive roadmap for overcoming therapeutic challenges in HCC through ferroptosis-based precision medicine.
Limitations:
Research on the role of NRF2 in GSH synthesis and ferroptosis is limited.
There are significant challenges in the clinical translation of ferroptosis-targeted therapies.
Conclusion:
The article identifies future research directions, including the need for deeper exploration of ferroptosis mechanisms and therapeutic applications in HCC.
