Abstract
OBJECTIVE: To investigate the prognostic significance of CXCL8 in cervical cancer and its effect on immune response based on bioinformatics method. METHODS: This study employs the HPA database to investigate CXCL8 expression in normal human tissues.The TIMER2.0 database is utilized to analyze CXCL8 expression across various types of cancer.Utilizing the TCGA database, we analyze the correlation between CXCL8 and the overall survival (OS) and progression-free interval (PFI) of patients with various tumors using R 4.3.2.Additionally, its association with immune checkpoint-related genes across various types of cancer is examined.We further analyze the association between CXCL8 expression and the expression of LAG3, CTLA4, PDCD1, and CD274 in cervical cancer.The TIMER database is used to study the association between CXCL8 and the extent of Tumor-Infiltrating Immune Cells (TIICs) infiltration.Enrichment analysis of genes related to CXCL8 is conducted using the LinkedOmics database. RESULT: CXCL8 is found in a wide range of normal human tissues.In the majority of tumor tissues, CXCL8 expression is elevated compared to their normal counterparts.There is a significant correlation between CXCL8 expression and the overall survival (OS) and progression-free interval (PFI) of patients with various tumors.CXCL8 expression is associated with the expression of diverse immune checkpoint-related genes and the extent of Tumor-Infiltrating Immune Cells (TIICs) infiltration.Genes related to CXCL8 participate in diverse immune-related processes in cervical cancer. CONCLUSION: CXCL8 plays a role in modulating immune infiltration, thereby influencing the prognosis of patients with various tumors, particularly those with cervical cancer.CXCL8 could potentially act as a biomarker for forecasting the prognosis and immune response of patients with tumors.
