NQO1 and cancer: The anticancer drug β‐Lap exerts its effects selectively on cancer cells that express high levels of NQO1, as these cancer cells generate elevated levels of toxic ROS through a futile cycle reaction involving β‐Lap and NQO1 (Bentle, Bey, et al. 2006, Bentle, Reinicke, et al. 2006, Bentle et al. 2007, Huang et al. 2012, Kim et al. 2014).
