Figure 4From: Fatty acid-binding protein 4 impairs the insulin-dependent nitric oxide pathway in vascular endothelial cellsFABP4 analysis in total cell lysates. HUVECs were treated with the indicated concentrations of FABP4 for 30 minutes followed by 600 nM insulin for 30 minutes. Representative blots are shown. The data represent the mean ± standard deviation from three independent experiments. *P < 0.05 vs. the untreated control.Back to article page
