Given the increased circulatory level of FABP3 in myocardial injury (9) and PAD (18), the obscurity about the role of endothelial FABP3 and the observed complexity about the role of FABP3 in LPS-treated endothelial cells from our data, for clarity, we performed a qPCR array containing 84 endothelial and vascular disease-related genes. The gene discussed is FABP3; the disease is peripheral arterial disease.
