We previously found that Otsuka Long-Evans Tokushima Fatty rats (OLETF), a model of type 2 DM, showed elevations in AKI markers such as neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) in the kidney after MI without an increase in serum creatinine (sCr) level3,4. Here, LCN2 is linked to acute kidney injury.
