Nrf2 targeting in overcoming ferroptosis evasion in head and neck cancer

Ferroptosis is a recently identified type of regulated cell death characterized by lipid peroxidation and redox-active iron accumulation. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a crucial regulator of genes involved in glutathione biosynthesis, antioxidant responses, lipid metabolism, and iron meta-bolism, contributing to the evasion of ferroptosis. Inhibiting the Nrf2 pathway has been shown to sensitize cancer cells to ferroptosis. In head and neck cancer cells, we found that activation of the Nrf2-antioxidant responsive element pathway leads to ferroptosis resistance, and inhibiting this pathway reverses ferroptosis evasion. Our study suggests that modulating the Nrf2 pathway could be a promising strategy to overcome resistance in cancer therapy for head and neck cancer. Further research is required to investigate the potential of ferroptosis induction in therapy-resistant head and neck cancer. Targeting Nrf2 through ferroptosis-based cancer therapy may be a novel and effective approach to reverse the resistance of head and neck cancer therapy.& COPY; 2023 Elsevier Inc.

Automated summary

Ferroptosis, characterized by lipid peroxidation and iron accumulation, is inhibited by the Nrf2 pathway. In head and neck cancer cells, activating the Nrf2-antioxidant responsive element pathway leads to resistance to ferroptosis, while inhibiting this pathway reverses this resistance. Modulating the Nrf2 pathway could be a promising strategy to overcome resistance in head and neck cancer therapy.
