Abstract
The analysis of the urinary proteome is a potential source of information regarding the kidney's physiopathology. A clear knowledge of the protein composition of normal urine is an essential prerequisite to looking at its pathology. Technological evolution in the field of proteomics (2-dimensional [2D] electrophoresis, equalization, mass spectrometry and exosomes) has greatly expanded the power of analysis, allowing the detection of almost 2,000 spots in normal urine, only a minor part of which has been characterized as isoforms of known proteins. The identity of most spots (80%) remains to be determined. The analysis of urine composition in nephrotic syndrome (glomerulosclerosis and me...
