LCN2 and acute kidney injury: As serum Cystatin C(Cys), a more accurate predictive biomarker of glomerular filtration rate (GFR), and neutrophil gelatinase-associated lipocalin (NGAL), an early predictive biomarker of AKI, have been successfully used in the liver diseases and LT studies [4,6,18-22], we approached to investigate the changes of renal RI values during anhepatic stage and early neohepatic stage as well as the Cys, NGAL after reperfusion in a rat liver transplantation model.
