Reactive oxygen species convert the omega-6 polyunsaturated fatty acid arachidonic acid into (15-HPETE); vitamin C mediates 15(S)-HPETE decomposition. 15(S)-HPETE initiates apoptosis in vascular smooth muscle cells. 15(S)-HPETE is a lipoxygenase metabolite that affects the expression of cell adhesion molecules (CAMs) involved in the adhesion of leukocytes and/or the accumulation of leukocytes in the vascular endothelium, these being the initial events in endothelial cell injury. 15(S)-HPETE induces a loss of cardiomyocytes membrane integrity. 15-(S)HPETE is a hydroperoxide that enhances the activity of the enzymes lipoxygenase [EC 1.13.11.12] and Na+, K+-ATPase [EC 3.6.3.9] of brain microvessels. Lipoxygenase(s) and Na+-K+-ATPase of brain microvessels may play a significant role in the occurrence of ischemic brain edema.
