Results: Comprehensive analysis indicates that the mutation rate of RA metabolism related genes in bladder cancer is about 20%, with significant gene amplification observed in RDH10 and CYP26B1. We identified a group of subsets with significantly increased RA metabolism activity in bladder cancer tumor epithelial cells and found that this subgroup was significantly associated with poor prognosis (p < 0.05). This evidence concerns the gene RDH10 and urinary bladder cancer.
