Lipid peroxidation is the oxidation of lipids that results in cellular damage. Lipid peroxidation can occur as a result of aging or as the result of cell migration in diseased tissue. Lipid peroxides signal oxidative stress in cells, causing decomposition and reactive byproducts. These reactive byproducts of lipid peroxidation include MDA, 4-HNE, and 8-isoprostane.
In nearly all cells exposed to oxygen, oxygen free radicals are produced during cellular aerobic respiration to produce energy. These free radicals are highly reactive oxygen species that cause damage to cell membranes and cytoplasmic contents on contact. The most commonly produced reactive oxygen species is superoxide, which is an unstable oxygen molecule carrying an extra electron. It is an important defensive antioxidant, serving to catalyze the inactivation of superoxide and preventing it from causing cellular damage.
Cancer is a condition in which abnormal cells form in the body and keep growing in an uncontrolled manner. Treating cancer therefore aims at killing these cells or preventing their multiplication, at the very least.
