WBP5 Expression Influences Prognosis and Treatment Response in Head and Neck Squamous Cell Carcinoma

초록

Objectives: Head and neck squamous cell carcinoma (HNSCC) is characterized by complex genetic alterations. This study aimed to identify WBP5 as a promising therapeutic target and evaluate the effect of WBP5 expression on prognosis and treatment response in HNSCC. Methods: Publicly available datasets were comprehensively analyzed to investigate WBP5 expression through comprehensive bioinformatics analysis and functional validation. Results: WBP5 was particularly overexpressed in HNSCC, as analyzed through the Gene Expression Profiling Interactive Analysis version 2 (GEPIA2) database and validated using multiple Gene Expression Omnibus (GEO) datasets. Analysis with UALCAN confirmed that WBP5 expression was significantly higher in advanced cancer stages and tumor grades than that of normal samples. A Kaplan-Meier analysis demonstrated that patients overexpressing WBP5 had a poor prognosis. Moreover, WBP5 expression correlated with the overexpression of the epidermal growth factor receptor in HNSCC. In vitro experiments revealed that WBP5 knockdown significantly reduced FaDu cell proliferation and viability. Furthermore, silencing WBP5 enhanced cisplatin sensitivity, indicating its potential role in chemoresistance. Conclusions: These results indicate that WBP5 could act as a prognostic marker and a viable therapeutic target in HNSCC. Modulating WBP5 expression may represent a novel strategy to enhance treatment efficacy. Future studies should elucidate the precise mechanisms of WBP5 action and develop targeted therapies. This integrated approach, combining a comprehensive analysis of publicly available datasets with in vitro experimental validation provides strong evidence for the clinical significance of WBP5 in HNSCC.
