Overview

Review synthesizes GPX4's dual role in ferroptosis and immune metabolism, suggesting precision strategies for therapy.

Key Points

This review examines the multifaceted role of GPX4 in the tumor microenvironment, particularly its regulatory functions beyond ferroptosis.
Synthesize recent advances in enzymology, immunology, and cancer metabolism.
Propose a lipid peroxidation threshold framework defining GPX4's impact across various cell types.
Discuss combination strategies involving GPX4 modulation and targeting of immune components.
GPX4 establishes cell-type-specific lipid peroxidation thresholds affecting ferroptosis susceptibility.
Therapeutic resistance to GPX4 inhibitors occurs due to Nrf2 and FSP1 pathways.
Rational combinations with ICB and myeloid-derived suppressor cells are suggested for enhanced efficacy.
