Atherogenesis, the formation of atherosclerotic plaques, is a complex process
that involves several mechanisms, including endothelial dysfunction,
neovascularization, vascular proliferation, apoptosis, matrix degradation,
inflammation, and thrombosis. The pathogenesis and progression of atherosclerosis
are explained differently by different scholars. One of the most common theories
is the destruction of well-balanced homeostatic mechanisms, which incurs the
oxidative stress. And oxidative stress is widely regarded as the redox status
realized when an imbalance exists between antioxidant capability and activity
species including reactive oxygen (ROS), nitrogen (RNS) and halogen species,
non-radical as well as free radical species. This occurrence results in cell
injury due to direct oxidation of cellular protein, lipid, and DNA or via cell
death signaling pathways responsible for accelerating atherogenesis. This paper
discusses inflammation, mitochondria, autophagy, apoptosis, and epigenetics as
they induce oxidative stress in atherosclerosis, as well as various treatments
for antioxidative stress that may prevent atherosclerosis.
