Urine samples of the RCCC patients and healthy controls were collected in the morning.Weak cation exchange (WCX) bead-based MALDI-TOF MS technique was applied in detecting differential protein peaks in the urine of RCCC. ClinProTools2.2 software was utilized to determine the characteristic proteins in the urine of RCCC patients for the predictive model of RCCC.Results The technique identified 160 protein peaks in the urine that were different between RCCC patients and health controls; and among them, there was one peak (molecular weight of 2221.71 Da) with statistical significance (P=0.0304). With genetic algorithms and the support vector machine, we screened out 13 characteristic protein peaks for the predictive model.Conclusions The application of WCX magnetic bead-based MALDI-TOF MS in detecting differentiallyexpressed proteins in urine may have potential value for the early diagnosis of RCCC.展开更多
