Chemotherapy-Induced Tissue Injury: An Insight Into The Role Of Extracellular Vesicles-Mediated Oxidative Stress Responses, Chontida Yarana, Daret K. St. Clair

Toxicology and Cancer Biology Faculty Publications

The short- and long-term side effects of chemotherapy limit the maximum therapeutic dose and impair quality of life of survivors. Injury to normal tissues, especially chemotherapy-induced cardiomyopathy, is an unintended outcome that presents devastating health impacts. Approximately half of the drugs approved by the Food and Drug Administration for cancer treatment are associated with the generation of reactive oxygen species, and Doxorubicin (Dox) is one of them. Dox undergoes redox cycling by involving its quinone structure in the production of superoxide free radicals, which are thought to be instrumental to the role it plays in cardiomyopathy. Dox-induced protein oxidation changes …
