However, its role in cervical cancer remains unclear. Methods: We aimed to demonstrate the relationship between INHBA expression and pan-cancer using The Cancer Genome Atlas (TCGA) database. Next, we validated INHBA expression in cervical cancer using the Gene Expression Omnibus (GEO) database, including GSE7803, GSE63514, and GSE9750 datasets. Enrichment analysis of INHBA was performed using the R package \"clusterProfiler.\" We analyzed the association between immune infiltration level and INHBA expression in cervical cancer using the single-sample gene set enrichment analysis (ssGSEA) method by the R package GSVA. We explored the association between INHBA expression and prognosis using the R package \"survival\". Results: Pan-cancer data analysis showed that INHBA expression was elevated in 19 tumor types, including cervical cancer. We further confirmed that INHBA expression was higher in cervical cancer samples from GEO database and cervical cancer cell lines than in normal cervical cells. Survival prognosis analysis indicated that higher INHBA expression was significantly associated with reduced Overall Survival (p = 0.001), disease Specific Survival (p = 0.006), and Progression Free Interval (p = 0.001) in cervical cancer and poorer prognosis in other tumors. GSEA and infiltration analysis showed that INHBA expression was significantly associated with tumor progression and some types of immune infiltrating cells. Conclusion: INHBA was highly expressed in cervical cancer and was significantly associated with poor prognosis. Meanwhile, it was correlated with immune cell infiltration and could be used as a promising prognostic target for cervical cancer.", "claims": [{"id": "claim-method", "statement": "To identify the prognostic value of markers for cervical cancer, we evaluated the correlation between high expression of INHBA and patients’ survival time using Kaplan-Meier analysis with Cox regression, including OS, DSS, and PFI.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:35058963", "locator": "sections[11] \"3.3 Association Between INHBA Expression and Cancer Patients Survival Prognosis\" paragraph 2", "quote": "To identify the prognostic value of markers for cervical cancer, we evaluated the correlation between high expression of INHBA and patients’ survival time using Kaplan-Meier analysis with Cox regression, including OS, DSS, and PFI."}], "state": "complete"}, {"id": "claim-data-access", "statement": "Publicly available datasets were analyzed in this study.
