Bioinformatics analysis and clinical validation identify FBXW9 as a biomarker in bladder urothelial carcinoma

F-box and WD repeat domain-containing protein 9 (FBXW9), a member of the F-box protein family, is dysregulated and involved in the progression of human malignancies. However, its functional mechanisms and clinical significance in bladder urothelial carcinoma (BLCA) remain poorly understood. This study aimed to systematically investigate the diagnostic and prognostic value of FBXW9 in BLCA.
