In addition, several oxylipins, including PGD2 (p = 0.001) and 15-lipoxygenase (LOX) metabolites (15-hydroxyeicosatetraenoic acid [15-HETE] (p = 0.005), 15-hydroxyeicosapentaenoic acid [15-HEPE] (p = 0.020), and 17-hydroxydocosapentaenoic acid [17-HDoHE] (p = 0.020)), increased in the aneurysm area. The gene discussed is LOX; the disease is aneurysm.
