Detoxification of stress caused by reactive lipid peroxidation can be helped by ALDH1A1 (EC 1.2.1.36) a putative cancer stem cell marker [18] belonging to a superfamily of NAD(P)+-dependent enzymes that catalyze the oxidation of a wide variety of endogenous and exogenous aldehydes to their corresponding carboxylic acids [18, 19]. Here, ALDH1A1 is linked to cancer.
