Abstract
Subsequent to the publication of the above article, the authors have realized that there were errors associated with Figs. 1c and 2b. In Fig. 1c, the authors noted that the same data were incorrectly presented for the 'Untreated cells" and 'DMSO' dot‑blot experiments. After having re‑examined their source data, the authors were able to confirm that the data correctly shown for the 'Untreated cells' experiment had inadvertently been included in the Figure as the data for the 'DMSO' experiment. Additionally, in Fig. 2b, the authors noticed that the percentage of untreated cells with active caspase‑3 was missing (the label for the 'No antibody' experiment). Corrected versions of Figs. 1 (including the correct data for the 'DMSO' dot blot) and 2 (with the label now incorporated) are shown opposite. Note that these changes do not affect the results or the conclusions reported in this paper, and all the authors agree to this correction. The authors apologize to the Editor and to the readership of the Journal for any inconvenience caused.
