In the original version of this article (1), two instances of inadvertent duplication of crystal violet staining images occurred in Fig. 1D (control shRNA conditions in MDA-MB-468 and BT-20) and in Fig. 1F (0 μmol/L gefitinib control conditions in MDA-468 and BT-20). In addition, the same set of STAT3 Western blot bands was inadvertently duplicated in Fig. 3A (BT-20 and HCC1937). These errors have been corrected in the latest online HTML and PDF versions of the article. The authors regret these errors.
