SRD5A3 stood out as one of genes upregulated in CDDP-resistant T24 cells compared to parental T24 cells, with log2FoldChange = 1.41 and P < 0.0001 (Fig. 1A), which provoked us to characterize the role of SRD5A3 in the context of bladder cancer. This evidence concerns the gene SRD5A3 and urinary bladder carcinoma.
