LCN2 and acute kidney injury: Surprisingly, renal mRNA levels of the AKI marker lipocalin 2 (Lcn2; also known as neutrophil gelatinase–associated lipocalin [Ngal]) and kidney injury molecule-1 (Kim1, also named Tim1 and Havcr1), as well as renal mRNA levels of the pro–inflammatory cytokines interleukin (Il)–1 beta, Il–6 and tumor necrosis factor (Tnf) did not differ between sham or IR-injured kidneys of Trpv4 KO and WT mice (Fig. 2A–E).
