  • Title: Oxidized low-density lipoprotein, a two-faced Janus in coronary artery disease?
    Author: Parthasarathy S, Santanam N, Augé N.
    Journal: Biochem Pharmacol; 1998 Aug 01; 56(3):279-84. PubMed ID: 9744562.
    Abstract:
    The word antioxidant has become a household term, and every day we are bombarded with claims of antioxidant protection against a host of diseases. Atherosclerosis, cancer, gastric ulcers, memory loss, rheumatoid arthritis, endometriosis, pregnancy complications, hypertension, stroke, and a host of other diseases have been suggested to be induced by oxidative stress, and antioxidants have been suggested to be beneficial in the prevention and treatment of these disorders. While some of these may be exuberant claims, atherosclerosis is one disease in which the oxidation hypothesis has taken firm roots. The oxidation of low-density lipoprotein (LDL) has been suggested to be a key step in the initiation of the early atherosclerotic lesion. A number of proatherogenic effects have been described for both the protein and lipid components of oxidized low-density lipoprotein. In this commentary, a brief description of the involvement of oxidation and the potential for antioxidant treatment for cardiovascular disease will be provided. However, there are innumerable questions plaguing the hypothesis; this commentary, therefore, will also serve as a devil's advocate and propose that some form of oxidation might actually be beneficial.
