Importance
There is a large body of evidence suggesting that oxidative modifications of low-density lipoproteins (LDL) contribute significantly to the initiation and/or progression of atherosclerosis. Circulating LDL particles are able to penetrate the endothelium of arterial walls and become oxidized, promote inflammation, and drive injury to the overlying endothelium and surrounding smooth muscle cells (Ross, 1999).
The oxidation of LDL in vitro is accelerated significantly by metal ions and is inhibited by chelating agents. Ox-LDL exhibited chemical and biological properties similar but not identical to cell-modified LDL (Steinbrecher et al. 1984). Many investigators studying oxidized LDL have used Cu2+-catalyzed oxidation as an experimental model (Gebicki et al. 1991). The Cu2+ oxidation model has been useful in exploring many facets of the LDL oxidation process and may have biological relevance.
