Noiri et al demonstrated that increase of urinary L-FABP was observed at 1 h after ischemia, even in the 5-min IRI group and urinary L-FABP was superior to BUN and urinary NAG for early and accurate detection of acute tubular necrosis in different models of animal AKI [23]. The gene discussed is FABP1; the disease is acute kidney tubular necrosis.
