In the original version of this article (1), the authors discovered that the cancer cell lines MCF-7, BT474, HCC827, and HCC1954 were contaminated with HeLa cells. All experiments in which these cell lines were used (Figs. 1–5) have been repeated with new stocks of cell lines obtained from the ATCC. The findings and conclusions remain the same. The errors have been corrected in the latest online HTML and PDF versions of the article. The authors regret this error.
