| pubmed-article:10357842 | pubmed:abstractText | Oxidation of lipoproteins is thought to be an early event in atherogenesis. To evaluate whether aortic lipoprotein lipid (per)oxidation contributes to atherosclerosis, we investigated the time-dependent changes to lipids and antioxidants in plasma and aortas of apolipoprotein E gene knockout (apoE-/-) mice receiving a high fat diet, and compared these changes with lesion development. Circulating buoyant lipoproteins and associated cholesterol (C), cholesteryl esters (CE), and alpha-tocopherol (alpha-TOH) increased within 1 month then remained largely constant up to 6 months. Coenzyme Q (CoQ) remained unchanged for the first 3 months and increased marginally after 6 months. With increasing duration of the diet, plasma lipids showed an increased propensity to undergo peroxyl radical-induced (per)oxidation. Absolute concentrations of aortic C, hydroperoxides and hydroxides of CE (CE-O(O)H) and alpha-TOH increased gradually while aortic CE increased more markedly with changes to cholesteryl linoleate being most pronounced. Aortic CoQ remained largely unchanged. Overall, the extent of aortic CE (per)oxidation remained low (</=1%) and the ratio of incremental changes of alpha-TOH to oxidizable lipid remained unchanged. Aortic biochemistry paralleled lesion formation, particularly that in the descending thoracic aorta.Together, our results show that progressing atherosclerosis in apoE-/- mice is associated with increased aortic lipid (per)oxidation as assessed by the concentrations of CE-O(O)H, measured directly by HPLC. This supports the oxidation theory. Measurement of aortic CE-O(O)H may be useful for mechanistic studies studying the relationship between inhibition of in vivo lipid (per)oxidation and atherosclerosis. | lld:pubmed |
