Schematic representation of study outcome. Doxorubicin increased eNOS and NOX4 levels, which results in eNOS uncoupling and decreased eNOS phosphorylation, enhancing ROS production. Meanwhile, ursolic acid increased eNOS production and phosphorylation, and inhibited NOX4 levels, decreasing ROS levels through eNOS activation and reduced eNOS uncoupling
