RACGAP1 and urinary bladder cancer: Kaplan–Meier curves for disease-specific survival in patients with bladder cancer were plotted according to the relative expression levels of RACGAP1 of two GEO cohorts (GSE13507 and GSE32548), and the results indicated that patients with RACGAP1-high had poorer disease-specific survival than those with RACGAP1-low (Fig. 6D).
