A crucial role in renal pathophysiology is played by hydrogen sulphide (H<jats:sub>2<\/jats:sub>S) that is produced excessively by the kidney; however, the data regarding H<jats:sub>2<\/jats:sub>S bioavailability are inconsistent. We hypothesize that early type 1 diabetes (T1D) increases H<jats:sub>2<\/jats:sub>S production by a mechanism involving hyperglycaemia\u2010induced alterations in sulphur metabolism. Plasma and kidney tissue collected from T1D double transgenic mice were subjected to mass spectrometry\u2010based proteomic analysis, and the results were validated by immunological and gene expression assays.T1D mice exhibited a high concentration of H<jats:sub>2<\/jats:sub>S in the plasma and kidney tissue and histological, showed signs of subtle kidney fibrosis, characteristic for early renal disease. The shotgun proteomic analyses disclosed that the level of enzymes implicated in <jats:italic>sulphate activation modulators, H<jats:sub>2<\/jats:sub>S\u2010oxidation<\/jats:italic> and <jats:italic>H<jats:sub>2<\/jats:sub>S\u2010production<\/jats:italic> were significantly affected (ie 6 up\u2010regulated and 4 down\u2010regulated). Gene expression results corroborated well with the proteomic data. Dysregulation of H<jats:sub>2<\/jats:sub>S enzymes underly the changes occurring in H<jats:sub>2<\/jats:sub>S production, which in turn could play a key role in the initiation of renal disease. The new findings lead to a novel target in the therapy of diabetic nephropathy.
