Oxidative stress in heart and brain by the cancer chemotherapeutic drug adriamycin (ADR), used for treating solid tumors, is well established. Long‐term treatment with ADR in breast cancer patients has led to symptoms of cardiomyopathy. Less well recognized, but increasingly well documented, is cognitive dysfunction. After chemotherapy, free radical‐mediated oxidative stress has been reported in both heart and brain. We recently showed a significant increase in protein oxidation and lipid…

It is demonstrated that treatment with ADR led to an increased circulating level of tumor necrosis factor‐alpha in wild‐type mice and in mice deficient in the inducible form of nitric oxide (iNOSKO), and it is suggested that NO is an important mediator, coupling the effect of ADR with cytokine production and subsequent activation of iNOS expression.
