Urinary peptidomics analysis reveals proteases involved in diabetic nephropathy.


ABSTRACT: Mechanisms underlying the onset and progression of nephropathy in diabetic patients are not fully elucidated. Deregulation of proteolytic systems is a known path leading to disease manifestation, therefore we hypothesized that proteases aberrantly expressed in diabetic nephropathy (DN) may be involved in the generation of DN-associated peptides in urine. We compared urinary peptide profiles of DN patients (macroalbuminuric, n?=?121) to diabetic patients with no evidence of DN (normoalbuminuric, n?=?118). 302 sequenced, differentially expressed peptides (adjusted p-value?
