Research advances in mechanism of doxorubicin-induced skeletal muscle dysfunction / 中国药理学与毒理学杂志

ABSTRACT

Doxorubicin(DOX) is a widely used clinical anti-tumor drug for cancer. Unfortunately, DOX can also cause skeletal muscle dysfunction in a dose-dependent manner, leading to a significant decline in the quality of life of cancer patients. In this paper, we summarize the toxic effects of DOX, the characteristics of DOX-induced skeletal muscle dysfunction and its related mechanisms. We focus on pathological mechanisms, including oxidative stress, Ca2+overload, mitochondrial energy metabolism disorder, autophagy and apoptosis, nitric oxide concentration and amino acid metabolism and myogenic regulatory factor expression. Research prospects are outlined. It is expected to provide a theoretical basis for the clinical study of DOX toxicity.
