This article (1) has been retracted at the request of the editors. The editors were made aware of concerns regarding potential manipulation of data in the article. An internal review by the editors determined that multiple tubulin Western blot bands appear to be duplicated in Figs. 3A and 6D. The authors were not able to provide the original data to dispel these concerns.

Fusco) did not agree to the retraction; two authors (A. Curcio and C. Indolfi) take no position; 10 authors (F. Pentimalli, A.J.P. Klein-Szanto, R. Visone, I. De Martino, C. Morisco, L.
