摘要

Background

Cervical cancer poses a substantial global health challenge. Estrogen-related receptor alpha (ERRα) is a central regulator of cellular energy metabolism associated with poor cancer prognosis. However, the effect of ERRα expression on cervical cancer prognosis and immune infiltration has not been explored. This study aims to clarify the expression pattern and role of ERRα in cervical cancer.

Methods

We analyzed ERRα expression and its clinical prognosis in cervical cancer using multiple databases, including The Cancer Genome Atlas (TCGA) and Tumor Immune Estimation Resource (TIMER). The results were further validated through immunohistochemistry (IHC) on 221 cervical cancer tissue samples. Furthermore, Kaplan-Meier and Cox regression analyses were used to assess the clinical significance of ERRα in cervical cancer patients. All calculations were performed using the R package.

Results

ERRα expression was significantly higher in cervical cancer tissues compared to normal tissues. High ERRα expression was associated with poor overall survival (OS), disease-specific survival (DSS), and progression-free survival (PFS). Multivariate Cox regression analysis confirmed ERRα as an independent prognostic factor. Additionally, ERRα expression correlated with various immune cell types and immune checkpoints, indicating its role in the tumor immune microenvironment.

Conclusions

ERRα emerges as a promising prognostic biomarker in cervical cancer, influencing immune cell infiltration and potentially guiding personalized therapeutic approaches. Future investigations are warranted to delineate the mechanistic pathways through which ERRα contributes to cervical cancer progression and to assess its viability as a target for innovative immunotherapy strategies.
