Doxorubicin (DOX)-induced cardiotoxicity is widely studied using C57BL/6 mice. However, potential substrain differences between C57BL/6J (6J) and C57BL/6N (6N) remain unexamined. Comparative studies are needed to improve preclinical reproducibility and translation. Fifteen-week-old male 6N and 6J mice received either DOX (8 mg/kg/week for 3 weeks) or saline. Body weight was monitored weekly, followed by...
