Circulating FABP4 is taken up by kidney. Blood, kidney, liver and heart were collected at indicated time points after intravenous injection of ¹²⁵I-labeled recombinant FABP4 (¹²⁵I-FABP4) to assess FABP4 uptake by each tissue. The data were expressed as the percent injected dose per gram tissue (%dose/g). n = 5. ***p < 0.001.
