Researchers use cachexia model to assess cancer-derived myocardial impairments Oncotarget recently published "Evaluation of cancer-derived myocardial impairments using a mouse model" which reported that Myocardial damage in cancer patients is emphasized as a cause of death; however, there are not many murine cachexia models to evaluate cancer-derived heart disorder. Using the mouse cachexia model that they established previously, the authors investigated myocardial damage in tumor-bearing mice. When rat cardiomyoblasts were treated with mouse cachexia model ascites and subjected to flux analysis, both oxidative phosphorylation and glycolysis were suppressed, and the cells were in a quiescent state. These results are in good agreement with those previously reported on cancerous myocardial damage.
