Urinary peptidomics analysis reveals proteases involved in diabetic nephropathy [PDF]

, 2017
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 ...
