英文摘要

Editor′s Highlight: Sensitive and early noninvasive biomarkers of renal toxicity are needed to augment or replace current biomarkers. This report describes the development and validation of two bioassays for mouse urinary KIM-1 that may be of clinical value. Using a microbead-based assay and a quantitative dipstick assay, these assays demonstrated sensitivity and stability for detection of KIM-1 in models of renal toxicity when other biomarkers remained unchanged.Kidney injury molecule-1 (KIM-1) has been qualified by the Food and Drug Administration and European Medicines Agency as a urinary biomarker to monitor preclinical nephrotoxicity in rats and on a case-by-case basis for the translation of potentially nephrotoxic drugs into first-in human studies. Although mouse models are widely employed in preclinical studies, few urinary biomarker studies have been performed in mice due to limited urine availability and lack of sensitive assays. Here, we report the development and validation of two different assays for quantitative assessment of mouse urinary KIM-1 (uKIM-1) and compare the sensitivity of KIM-1 relative to other standard markers in ischemia reperfusion and aristolochic acid (AA)induced kidney injury in mice. A sensitive, reproducible, and quantitative microbead-based KIM-1 ELISA was established, which requires only 10 l urine for triplicate determination with an assay range of 12.21 pg/ml to 50ng/ml. The second assay is a laminar flow dipstick assay, which has an assay range of 195 pg/ml to 50ng/ml and provides quantitative assessment of KIM-1 in 15min. uKIM-1 levels increased with increasing time of ischemia or time after AA administration. After only 10-min ischemia followed by 24-h reperfusion, uKIM-1 was significantly elevated by 13-fold, whereas serum creatinine (sCr), blood urea nitrogen, N-acetyl--glucosaminidase (NAG), and proteinuria levels did not change. After AA administration, uKIM-1 levels were significantly upregulated by greater than threefold within 12h, whereas sCr and NAG levels were unchanged. Mouse KIM-1 was stable for multiple freeze-thaw cycles, for up to 5 days at room temperature and up to at least an year when stored at 80C.
