NADPH oxidase subunits protein expression in the kidney. Effect of OPLE on renal protein expressions of p22phox and p67phox NADPH oxidase subunit 4-week (A) or 12-week study (B). (i and iii) Representative western blots showing bands of p22phox, p67phox and β-actin as an internal control. Control (C), Diabetes Control (DC) and Diabetes + OPLE 1000 mg kg−1 (D + OPLE 1000); (ii and iv) Densitometric analysis of protein renal expression of p22phox and p67phox NADPH oxidase subunits. Data are expressed as mean ± SEM of four experiments for each group. a P < 0.05; aa P < 0.01; vs. corresponding control; b P < 0.05, vs. corresponding diabetes control.
