Chronic kidney disease (CKD) is a gradual loss of kidney function and has an increased prevalence rate worldwide. Our study was intended to identify potential biomarkers of progression using urine proteomics. This preliminary study consisted of 32 patients with stage V CKD. Urine samples were subjected to liquid chromatography-mass spectrometry (LCMS), and the network of protein interaction was analyzed using STRING. A total of 135 proteins were identified, of which 35 were listed as candidates based on their clinical significance. Protein- protein interaction study provides novel insights into the functional constitution of the proteome, selecting urine as a source of biomarkers. The present study observed that the potential markers such as EndoG, HPX, APN, AnxA1, Mic60, LONP1, and HYOU1 correlate with renal damage and its progression to CKD stage V.
