Clinical Report: Ferroptosis Mediates the Anti-Cancer Effects of Quercetin

Overview

This study investigates the role of quercetin in inducing ferroptosis in oral squamous cell carcinoma (OSCC) cells through the LGR4/NF-κB/GPX4 pathway. Quercetin demonstrated a dose-dependent reduction in OSCC cell viability.

Background

Oral squamous cell carcinoma (OSCC) is a prevalent malignancy with poor prognosis due to chemotherapy resistance and severe side effects. Understanding the mechanisms of compounds like quercetin that can induce ferroptosis may provide new avenues for OSCC treatment.

Data Highlights

FindingDetails
Quercetin EffectReduced OSCC cell viability in a dose-dependent manner.
Ferroptosis InhibitionLiproxstatin-1 counteracted quercetin-induced cell death.
GPX4 ExpressionQuercetin decreased GPX4 expression in OSCC cells.
Pathway SuppressionQuercetin suppressed the LGR4/NF-κB signaling pathway.
Mechanistic InsightLGR4 upregulates IKKβ, leading to NF-κB activation and GPX4 transcription.

Key Findings

  • Quercetin induces ferroptosis in OSCC cells.
  • Co-treatment with liproxstatin-1 inhibits quercetin's effects.
  • Quercetin reduces GPX4 expression by inhibiting the LGR4/NF-κB pathway.
  • LGR4 activation promotes NF-κB signaling, contributing to OSCC cell survival.
  • Ferroptosis may play a significant role in quercetin's anti-OSCC activity.

Clinical Implications

Further exploration of the LGR4/NF-κB/GPX4 pathway may enhance therapeutic strategies against OSCC.

Conclusion

Quercetin's ability to induce ferroptosis through the LGR4/NF-κB/GPX4 pathway presents findings that warrant further research.
