Through RT-qPCR experiments and bioinformatic analysis based on the TCGA database, we found that PEDS1 has significant differences in two types of urothelial carcinoma and is related to the worse survival in both types of urothelial carcinoma, particularly in UTUC (Figs. 3A–D and S2A–C). Here, PEDS1 is linked to urothelial carcinoma.
