Abstract

Objective: To explore whether urine proteome can reflect the difference between obese and normal weight people.
Methods: Urine samples from obese and normal weight people were collected and identified by non-label quantitative proteomics using high performance liquid chromatography tandem mass spectrometry (LC-MS/MS). The difference proteins of urine proteome between obese and normal weight people were screened for protein function and biological pathway analysis. The urine proteome of obese individuals was compared with that of normal weight people, and the common differential proteins were counted to analyze the protein function and biological pathways. Reported biomarkers of obesity were searched in the urine proteome of obese individuals.
Results: 38 different proteins can be identified in the urine proteome of obese people compared with normal weight people, some of which have been reported to be related to metabolism and obesity, and the biological processes of differential proteins are also related to metabolism and other processes. 8 common differential proteins in the urine proteome of obese individuals and normal weight people, among which some proteins have been reported to be related to metabolism and obesity, and the biological processes of differential proteins are also related to metabolism and other processes. Among the differential proteins in the urine proteome of obese individuals compared with the normal weight people, the reported obesity biomarkers can be matched.
Conclusions: The urine proteome can distinguish the obese people from the normal weight people, and the differential proteins in the urine proteome have key proteins that are known to be related to obesity and metabolism, and the biological processes of differential proteins also related biological processes such as nutrition and metabolism. Urine proteome has the potential to explore the pathogenesis of obesity and provide personalized treatment.
