Abstract:
Esophageal squamous cell carcinoma (ESCC) is a deadly disease that requires extensive research. Here, we review the current understanding of the functions of the nuclear factor erythroid-derived 2-like 2 (NRF2) signaling pathway in the esophagus. Genomic data suggest that gene mutations and several other mechanisms result in NRF2 hyperactivation in human ESCC. As a consequence, NRF2high ESCC is more resistant to chemoradiotherapy and associated with poorer survival than NRF2low ESCC. Mechanistically, we believe NRF2, functioning as a transcription factor, causes an esophageal phenotype through regulation of gene transcription. We discuss metabolism, mitochondria, proteasomes, and several signaling pathways as downstream players that may contribute to an esophageal phenotype due to NRF2 hyperactivation. Finally, strategies are proposed to target the NRF2 signaling pathway for therapy of NRF2high ESCC.
Insights
The nuclear factor erythroid-derived 2-like 2 (NRF2) pathway is hyperactivated in esophageal squamous cell carcinoma (ESCC), leading to treatment resistance and poor survival. Targeting NRF2 offers a potential therapeutic strategy for ESCC.
Area of Science:
- Oncology
- Molecular Biology
- Cellular Signaling
Background:
- Esophageal squamous cell carcinoma (ESCC) is a significant global health challenge.
- The nuclear factor erythroid-derived 2-like 2 (NRF2) signaling pathway plays a critical role in cellular defense mechanisms.
- Dysregulation of NRF2 is implicated in various cancers, including ESCC.
Purpose of the Study:
- To review the current understanding of NRF2 pathway functions in the esophagus.
- To explore the mechanisms of NRF2 hyperactivation in human ESCC.
- To discuss the implications of NRF2 dysregulation for ESCC prognosis and treatment.
Main Methods:
- Review of genomic data and existing literature on NRF2 in ESCC.
- Analysis of NRF2's role as a transcription factor.
- Discussion of downstream molecular pathways affected by NRF2 hyperactivation.
Main Results:
- Genomic alterations frequently lead to NRF2 hyperactivation in ESCC.
- NRF2-high ESCC exhibits increased resistance to chemoradiotherapy.
- NRF2-high ESCC is associated with poorer patient survival outcomes.
Conclusions:
- NRF2 hyperactivation drives an esophageal cancer phenotype through transcriptional regulation.
- Metabolism, mitochondria, and proteasome function are key downstream effectors of NRF2 in ESCC.
- Targeting the NRF2 pathway presents a promising therapeutic avenue for NRF2-high ESCC.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
