Abstract:
Objective To screen early urine protein markers for minimal change nephropathy.Methods Adriamycin nephropathy was employed as minimal change nephropathy model.Urinary protein and ConA captured glycoproteins were respectively profiled.Results By profiling urine proteome,25 differential proteins were identified.These differential proteins were from leaked plasma proteins,secreted proteins from immuno-and inflammatory cells,specifically asecreted proteins from urinary tract,and so on.They took part in different pathogenic process,eg.hemodynamic changes,podocytes injury,immunological disorder and so on.By profiling ConA-enriched urinary glycoproteome,21 differential proteins were identified,among which 12(57%) were different from the above 25 differential proteins.This indicates that the knowledge of urine glycoproteome is complementary to urine proteome in understanding kidney condition.Conclusion These differential proteins can be potential indicators of minimal change nephropathy,and can help better understand the pathogenesis by further studying their functions.
