Abstract

Owing to its availability, ease of collection and correlation with physiology and pathology, urine is an attractive source for clinical proteomics/peptidomics. However, the lack of comparable data sets from large cohorts has greatly hindered the development of clinical proteomics. Here, we report the establishment of a reproducible, high-resolution method for peptidome analysis of naturally occurring human urinary peptides and proteins - ranging from 800-17,000 Da - using samples from 3,600 individuals analyzed by capillary electrophoresis coupled to mass spectrometry (CE-MS). All processed data were deposited in a SQL database. This database currently contains 5,010 relevant unique urinary peptides that serve as a pool of potential classifiers for diagnosis and monitoring of various diseases. As an example, by using this source of information, we were able to define urinary peptide biomarkers for chronic kidney diseases (CKD) allowing diagnosis of these diseases with high accuracy. Application of the CKD-specific biomarker set to an independent test cohort in the subsequent replication phase resulted in 85.5% sensitivity and 100% specificity. These results indicate the potential usefulness of CE-MS for clinical applications in the analysis of naturally occurring urinary peptides.
