Cathepsin S inhibition has a rapid potent effect on albuminuria. Kidney sections of 19 week old MRL-(Fas)lpr mice of all groups were stained for WT1 and nephrin to quantify podocytes per glomerular cross section (A). Representative images are shown in (B) at an original magnification of x400 (scale 25 µm). Urinary albumin/creatinine (A/C) ratio was determined every 2 weeks and is expressed at logarithmic scale (C). Note that the highest dose of RO5459072 reduced A/C ratio quickly at 2 log scales more than MMF. Blood urea nitrogen (BUN) levels were determined at the same time points. Note the linear increae of BUN with time in vehicle-treated mice, while all treatments significantly reduced BUN (D). Data are expressed as means ± SEM (n = 8 to 10 in each treatment group). *p < 0.05, **p < 0.01, ***p < 0.001 versus vehicle group. #p < 0.05 base line values versus week 19 values.
