title: [The formation of the urine proteome in healthy human].
abstract: In the review it was represented the modern ideas on the processes involved in the formation of the protein composition of the urine of healthy people. In the last decade the development of highly sensitive mass spectrometric methods for the detection of proteins has given impetus to the study of the protein composition of human body fluids, including urine. Modern methods of separation of complex protein mixtures and determination of the individual components of these mixtures that are used in proteomics, can detect in urine significant number of proteins and peptides of different origin. Little-known, but very important problem for biomedical research is a physiological variation of the protein composition of urine revealed by proteomics. Under physiological conditions, there are many factors that affect the filtration of plasma proteins in the glomeruli and reabsorption in the proximal tubules of the nephron. These include hypoxia, oxidative stress, changes in acid-base balance and blood pressure, the effects of parathyroid hormone, angiotensin-II and other regulators of water and electrolyte metabolism. It is shown that the close structural and functional relationship of processes of reabsorption in the proximal tubules of the nephron causes dependence modulation of sodium reabsorption, water, chloride, phosphate, bicarbonate, and changes in the various parts of the process of re-absorption of the protein.
