Following the publication of the above paper, it was drawn to the Editor's attention by a concerned reader that, for the Transwell assay data shown in Fig. 2C on p. 582, the '24 h/1 µM' and '24 h/2.5 µM' data panels contained an overlapping section of cellular data; in addition, the '24 h/Control' and '48 h/Control' panels in Fig. 2E similarly contained an overlapping section of data, such that data which were intended to show the results from differently performed experiments appeared to have been derived from the same original sources. Upon analyzing the data independently in the Editorial Office, it came to light that the '0 h/1 µM' and '12 h/2.5 µM' data panels in Fig. 2A (showing the results of scratch-wound assay experiments) also contained an overlapping area, albeit the 12 h/2.5 µM' data panel had been rotated through 180° relative to the '0 h/1 µM' panel.
