We the authors are retracting this Article as it has come to our attention that there has been inappropriate duplication of images between different figures of the published paper, and between figures in the paper and those in work previously published by the corresponding author (Hidalgo, I. et al. 2012). The figure panels affected are Figure 1d, Figure 3c, Figure 4e, Figures 6a, g, and Supplementary Figure 1b. The corresponding author, S. Gonzalez, was unable to supply a complete set of raw data on which the Article is based. The Centro Nacional de Investigaciones Cardiovasculares Carlos III and the first author I. Gonzalez-Valdes, together with the co-authors I. Hidalgo, A. Bujarrabal, E. Lara-Pezzi, L. Padron-Barthe, P. Garcia-Pavia, Pablo Gómez-del Arco, J.M. Redondo, J.M. Ruiz-Cabello, L.J.
