LCN2 and acute kidney injury: Renal mRNA levels of two sensitive AKI markers, lipocalin 2 (Lcn2; also known as neutrophil gelatinase-associated lipocalin [Ngal]) and hepatitis A virus cellular receptor 1 (Havcr1; also known as kidney injury molecule 1 [Kim1]), were not different between Cth+/+, Cth+/−, and Cth−/− mice (Fig. 2B,C).
