![عکس صفحه اول مقاله: Cellular, molecular and clinical aspects of vitamin E on atherosclerosis prevention Cellular, molecular and clinical aspects of vitamin E on atherosclerosis prevention](/preview/png/1995868.png)
Randomised clinical trials and epidemiologic studies addressing the preventive effects of vitamin E supplementation against cardiovascular disease reported both positive and negative effects, and recent meta-analyses of the clinical studies were rather disappointing. In contrast to that, many animal studies clearly show a preventive action of vitamin E in several experimental settings, which can be explained by the molecular and cellular effects of vitamin E observed in cell cultures. This review is focusing on the molecular effects of vitamin E on the cells playing a role during atherosclerosis, in particular on the endothelial cells, vascular smooth muscle cells, monocytes/macrophages, T cells, and mast cells. Vitamin E may act by normalizing aberrant signal transduction and gene expression in antioxidant and non-antioxidant manners; in particular, over-expression of scavenger receptors and consequent foam cell formation can be prevented by vitamin E. In addition to that, the cellular effects of α-tocopheryl phosphate and of EPC-K1, a composite molecule between α-tocopheryl phosphate and l-ascorbic acid, are summarized.
