To validate array CGH data on the amplified regions, copy number changes of the Olfr1184 and Rapsn genes on mouse chromosomal region 2D-E1, the Cyp2g1, Cyp2a5, Cyp2a22, Cyp2a12, and Rab4b genes on 7qA3, the Klhl18, Kif9, and Nradd genes on 9F2, and Stxbp4 and Cox11 genes on 11C-D were investigated by qPCR in 2 and 4 samples of invasive bladder tumors obtained at 20 and 26 weeks, respectively, after the initiation of BBN treatment (S3 Table). Here, STXBP4 is linked to urinary bladder neoplasm.
