Erratum: Selective killing of cancer cells by a small molecule targeting the stress response to ROS

Nature 475, 231–234 (2011) In this Letter we made errors in the description of the way we performed tumour measurements in the spontaneous (Fig. 2b and d) and the xenograft (Supplementary Fig. 9) mouse models. The legend of Fig. 2 incorrectly states that the graph of plotted tumour measurements represents tumour diameters from “grossly dissected tumours”.
