Similarly, en face imaging of the lesser curvature of aortic arch, an atherosclerosis-prone region of the vessel wall, showed more postprandial TG-rich neutral lipid accumulation in endothelial layers of the aorta in Atgl ECKO following an olive oil gavage compared with that of control mice (Figure 1G). The gene discussed is PNPLA2; the disease is atherosclerosis.
