Fig. 9From: NAD(P)H: quinone oxidoreductase 1 attenuates oxidative stress and apoptosis by regulating Sirt1 in diabetic nephropathyThe expression of NQO1 in the kidneys of patients with DN. A Expression of NQO1 in the kidneys of patients with DN or in normal control kidneys was determined by immunohistochemical staining (Scale bar, 100 μm, n = 15). B Model showing the effect of NQO1-regulated NAD+/NADH on Sirt1-mediated oxidative stress and apoptosis in HG-induced renal tubular cellsBack to article page
