Notably, the sEH Glu287Arg variant has lower PT activity and is associated with hyperlipidemia and calcification in CAD patients.13, 14, 15 As of today, the role of PT and EH activity of sEH on cholesterol metabolism has yet to be understood, so further investigations delineating the roles and molecular mechanism underlying the effect of EH and PT activity of sEH on cholesterol metabolism and atherosclerosis are warranted. This evidence concerns the gene EPHX2 and atherosclerosis.
