Thioredoxin reductase-1 levels in lymphocytes from diabetic nephropathic patients. Lymphocyte samples from patients with nephropathy secondary to type 2 diabetes (black columns) and age-matched controls (white columns) were assayed for thioredoxin reductase-1 (TrxR-1) by Western blot as described in Materials and Methods. A representative immunoblot is shown. β-actin has been used as loading control. The bar graphs show the densitometric evaluation and values are expressed as mean ± standard error of mean of 3 independent analyses on 16–21 patients per group. *P < 0.05 vs control; D.U., densitometric units
