Using the conventional Sanger’s method, we sequenced the PPARG and RXRA exons in 359 bladder tumors (199 of which were NMIBCs) from our CIT series of tumors (carte d’identité des tumeurs) and from a bank of samples collected at Strasbourg hospital, and in 25 bladder cell lines (Supplementary Table 1). Here, RXRA is linked to urinary bladder neoplasm.
