p53 deletion attenuates doxorubicin cardiotoxicity in mice; hypothesis-generating for cardioprotection in patients, pending clinical validation.
Does p53 deletion prevent doxorubicin-induced cardiac injury in mice?
p53 mediates doxorubicin-induced cardiotoxicity through oxidative stress and mitochondrial injury, highlighting a potential mechanistic target for preventing chemotherapy-induced heart failure.
Vélez et al. (2011) studied this question.
