Abstract
Background: Proteome studies for multiple renal diseases is bare. Methodology & results: Using isobaric tags for relative and absolute quantitation labeling, many differentially expressed proteins (DEPs) were identified in acute kidney injury (AKI), AKI+chronic kidney disease (CKD), diabetic CKD and nondiabetic CKD with or without IgA nephropathy (IgAN). Comparative analysis indicated that 34, 35, 17, 91 and 14 unique DEPs were found in AKI, AKI + CKD, CKD, diabetic CKD and nondiabetic CKD. Compared with nondiabetic CKD with IgAN, 47 unique DEPs were found in that without IgAN. Serum amyloid A1 (SAA1) and hepatocyte growth factor activator were unregulated in AKI and nondiabetic CKD without IgAN, respectively. Regenerating islet-derived protein 3-α (Reg3A) upregulation is associated with AKI and AKI + CKD patients. Conclusion: This research contributes to urinary biomarker discovery from multiple renal diseases.
Highlights
Proteome studies for multiple renal diseases is bare
In diabetic chronic kidney disease (CKD), 91 specific differentially expressed proteins (DEPs) were screened out, while 14 particular DEPs were discovered in nondiabetic CKD patients
In comparison with nondiabetic CKD with IgA nephropathy (IgAN), which contains 38 specific DEPs. 47 unique urinary proteins were found in nondiabetic CKD without IgAN
