In Figure 3 of this Letter, there were labelling errors on the x-axis in which the 05C48386 and 05C43079 cell-line labels were both duplicated. The labels should have corresponded to 05C44574, 05C48386, 03C23091 and 05C43079. The correct figure is shown here, and this has been corrected in the HTML and PDF version of the manuscript.
