Our analysis of the correlation between PRPF19 expression and the survival outcomes of bladder cancer patients, using the TCGA-BLCA dataset and the GSE13507 dataset, revealed that patients with high PRPF19 expression exhibited a significantly unfavorable prognosis in terms of both overall survival and disease-specific survival (Figures 1E–H). Here, PRPF19 is linked to urinary bladder carcinoma.
