Oxidation of lipoprotein Lp(a). A comparison with low-density lipoproteins
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1991Aimed at identifying possible mechanisms of the suggested high atherogenicity of Lp(a), its susceptibility for Cu(II)-induced oxidation was studied and compared with that of LDL. Since the content of antioxidants as well as the fatty acid pattern of a lipoprotein greatly affects its oxidizability, Lp(a) and LDL were characterized first with respect to ...

Low-density lipoprotein oxidation in essential hypertension
Journal of Hypertension, 1993To investigate the occurrence of enhanced low-density lipoprotein (LDL) oxidation as an additional factor promoting atherosclerosis progression in hypertensive patients.The oxidation of plasma LDL was investigated in a group of untreated patients with mild-to-moderate essential hypertension without clinically evident target organ damage and in a group ...

Chromium and human low-density lipoprotein oxidation
Journal of Trace Elements in Medicine and Biology, 2020Chromium is a catalytic metal able to foster oxidant damage, albeit its capacity to induce human LDL oxidation is to date unkown. Thus, we have investigated whether trivalent and hexavalent chromium, namely Cr(III) and Cr(VI), can induce human LDL oxidation. Cr(III) as CrCl3 is incapable of inducing LDL oxidation at pH 7.4 or 4.5.

Oximes as inhibitors of low density lipoprotein oxidation
Life Sciences, 2008Several lines of evidence support the hypothesis that the oxidation of low density lipoprotein (LDL) may play a crucial role in the initiation and progression of atherosclerosis. Various studies have shown a positive effect of antioxidant compounds on oxidative modification of LDL and atherogenesis.

Scavenger receptors and oxidized low density lipoproteins
Clinica Chimica Acta, 1999Oxidized LDL has been shown to exhibit a number of potentially proatherogenic actions and properties, including receptor-mediated uptake and lipid accumulation within macrophages. It has been postulated that rapid, unregulated uptake of oxidatively modified LDL could account for the transformation of monocyte-derived macrophages to foam cells in ...

Low density lipoprotein oxidation, antioxidants, and atherosclerosis
Current Opinion in Cardiology, 2000Oxidized low density lipoproteins (LDLs) are believed to be the most atherogenic form of LDL. However, although a number of experimental data support this concept, the protective role of antioxidants that may prevent LDL oxidation in atherosclerosis is only partially confirmed by studies in humans.

Low-density lipoprotein oxidation.
Italian heart journal : official journal of the Italian Federation of Cardiology, 2001Free radical mediated oxidation of low-density lipoproteins (LDL), which has been extensively studied in the last two decades, plays a central role in the development of the atherosclerotic plaque. Oxidation involves the lipid moiety of LDL in a chain reaction mechanism.

Effects of phosphatidylserine on the oxidation of low density lipoprotein
International Journal of Biochemistry, 19941. LDL was incubated in the presence of 1 microM CuSO4 for 18 hr at 37 degrees C. The content of lipoperoxides was found to be approx. 40 nmol MDA equivalents/mg LDL protein. The addition of 50 microM phosphatidylserine (PS) reduced the content of lipoperoxides to 15% of control values. 2.

Oxidation of low-density lipoprotein by hemoglobin–hemichrome
The International Journal of Biochemistry & Cell Biology, 2003Hemoglobin and myoglobin are inducers of low-density lipoprotein oxidation in the presence of H(2)O(2). The reaction of these hemoproteins with H(2)O(2) result in a mixture of protein products known as hemichromes. The oxygen-binding hemoproteins function as peroxidases but as compared to classic heme-peroxidases have a much lower activity on small ...
