Human studies by Valette et al. [9] and Yilmaz et al. [10] suggest that during the regenerative processes after kidney injury, NGAL is induced in proximal tubular epithelial cells and is a highly predictive biomarker of acute kidney injury (AKI), chronic kidney diseases (CKDs), and urinary tract infections (UTI). This evidence concerns the gene LCN2 and chronic kidney disease.
