Exercise Effects on Chemotherapy in Breast Cancer Mouse Models

Most people are aware by now that exercise has positive effects in “healthy” individuals and in patients with cancer. In cancer patients, exercise has been shown to reduce adverse events, improve quality-of-life and respiratory fitness, and even decrease the risk of breast cancer recurrence. These results, and many others, have prompted major national and international cancer organizations to make exercise recommendations. “There also is a growing body of evidence that exercise may directly alter the tumor microenvironment to influence tumor growth, metastasis, and response to anticancer therapies.” However, scientists and researchers have only scratched the surface of understanding the extent of the benefits that are capable of being harnessed by exercise. While research shows that exercise may impact tumors, the exercise prescription needed to induce these beneficial tumor-related outcomes is still unclear. In an effort to better harness the benefits of exercise, researchers from the University of Florida conducted a study on the effects of wheel running in breast cancer mouse models and chemotherapy. Their paper was published as the cover of Oncotarget’s Volume 12, Issue 18, and entitled, “Normal tissue and tumor microenvironment adaptations to aerobic exercise enhance doxorubicin anti-tumor efficacy and ameliorate its cardiotoxicity in retired breeder mice.” “The goal of this study was to characterize the exercise prescription by evaluating the aerobic adaptations in both the normal tissue and the tumor microenvironment. Moreover, doxorubicin was used to assess the adjuvant effects of aerobic exercise on chemotherapy efficacy and toxicity.” Full blog - https://www.impactjournals.com/journals/blog/oncotarget/new-study-how-exercise-boosted-chemotherapy-in-mice/ Sign up for free Altmetric alerts about this article - https://oncotarget.altmetric.com/details/email_updates?id=10.18632%2Foncotarget.28057 DOI - https://doi.org/10.18632/oncotarget.28057 Full text - https://www.oncotarget.com/article/28057/text/ Correspondence to - Zachary R.
