A total of 120 4-week-old broiler chickens were allotted to 12 pens and fed one of three diets including control, oxidized diet (5% oxidized oil), or antioxidant-added diet (500 IU vitamin E) for 2 weeks. Blood samples were collected at the end of feeding trial, and breast muscles were sampled immediately after slaughter. Breast meats were also collected 24 h after slaughter and used for meat q...
Elevated plasma concentration of the pro-atherogenic oxidized low density lipoprotein cholesterol (LDL) triggers adverse effects in pancreatic beta-cells and is associated with type 2 diabetes. Here, we investigated whether the endoplasmic reticulum (ER) stress is a key player coupling oxidative stress to beta-cell dysfunction and death elicited by human oxidized LDL. We found that human oxidiz...
It has been well documented that acute myocardial infarction is triggered by disruption of atherosclerotic plaques. Immunocytochemistry studies have shown that matrix metalloproteinase-1 (MMP-1) is specifically expressed by cells present in atherosclerotic plaques, including luminal and neovascular endothelial cells. Since MMP-1 degrades type I collagen, a major type of collagen in atherosclero...
PURPOSE To test the hypothesis that the accumulation of oxidized phospholipids (OxPL) in the macula is toxic to the retina unless neutralized by a variety of mechanisms, including binding by lipoprotein(a) [Lp(a)], which is composed of apolipoprotein(a) [apo(a)] and apolipoprotein B-100 (apoB). METHODS Human maculas and eyes from two Lp(a) transgenic murine models were subjected to morphologi...
To investigate the effect of RNA oxidation on normal cellular functions, we studied the translation of nonoxidized and oxidized luciferase mRNA in both rabbit reticulocyte lysate and human HEK293 cells. When HEK293 cells transfected with nonoxidized mRNA encoding the firefly luciferase protein were cultured in the presence of paraquat, there was a paraquat concentration-dependent increase in th...
We analyzed the influence of the atherogenic oxidized low density lipoproteins (LDL) on the activity of the platelet prothrombinase complex, a major contributor to overall thrombin formation in vivo. Platelet dependent thrombin generation was found to be strongly stimulated by in vitro oxidized LDL. The enhancement was additive to that observed with the platelet agonist thrombin. Oxidized LDL i...
