Inhibition of cytochrome P450 epoxygenase promotes endothelium-to-mesenchymal transition and exacerbates doxorubicin-induced cardiovascular toxicity.

Doxorubicin (DOX) is a potent chemotherapy widely used in treating various neoplastic diseases. However, the clinical use of DOX is limited due to its potential toxic effect on the cardiovascular system. Thus, identifying the pathway involved in this toxicity may help minimize chemotherapy risk and improve cancer patients' quality of life. Recent studies suggest that Endothelial-to-Mesenchymal transition (EndMT) and endothelial toxicity contribute to the pathogenesis of DOX-induced cardiovascular toxicity. However, the molecular mechanism is yet unknown. Given that arachidonic acid and associated cytochrome P450 (CYP) epoxygenase have been involved in endothelial and cardiovascular function, we aimed to examine the effect of suppressing CYP epoxygenases on DOX-induced EndMT and cardiovascular toxicity in vitro and in vivo.
