TP53 and endometrial cancer: <h4>Background</h4>Oxidative stress plays a crucial role in the development and treatment response of endometrial cancer, yet the antioxidant defense mechanisms in different tumor subtypes remain unclear.<h4>Methods</h4>We investigated the cellular response to oxidative (menadione) and genotoxic (doxorubicin) stress in two TP53-mutated endometrial cancer cell lines, AN3CA and KLE.
