Of the 9 proteins with apparent altered glycosylation (rather than simply an increase in total concentration), 6 were previously identified as released by bladder cancer cell lines in vitro [24] (mucin-1 (MUC1), golgi apparatus protein 1 (GLG1), endoplasmin (HSP90B1), prostatic acid phosphatase (ACPP), Ig gamma-2 chain C region (IGHG2), and deoxyribonuclease-2-alpha (DNASE2A)), and 3 were not (voltage-dependent anion-selective channel 1, carbonic anhydrase 1 and bile salt-activated lipase 11) . This evidence concerns the gene MUC1 and urinary bladder cancer.
