“…Unfortunately, the clinical use of this drug is hampered due to the cumulative dose‐related cardiotoxicity and vascular damage, which may ultimately lead to a severe and irreversible form of vascular injury and cytotoxicity (Ohlig et al, ). Although numerous underlying mechanisms have been proposed, most studies support the view that an increase in oxidative stress, can be evidenced by increases in the levels of reactive oxygen species (ROS; Zhao et al, ), and lipid peroxidation (Benzer, Kandemir, Ozkaraca, Kucukler, & Caglayan, ), along with reductions in the levels of the antioxidant enzymes (superoxide dismutase [SOD], catalase [CAT], glutathione), mitochondrial membrane potential (MMP) and sulfhydryl groups (Hsu et al, ; Magalhães et al, ), in the pathogenesis of DOX‐induced vascular injury and cytotoxicity. This suggests that reductions in the levels of diverse antioxidant enzymes represent a common response to DOX treatment (Li, Danelisen, & Singal, ).…”
