Neutrophil gelatinase-associated lipocalin (NGAL), cartilage intermediate layer protein 2 (CILP-2), 6-phosphogluconolactonase (6-PGLS), annexin A5, galectin 3, and protein S100-P were finally selected as final candidate urinary AKI biomarkers. The gene discussed is CILP2; the disease is acute kidney injury.
