Western blot analyses were performed using a previously published method [15 (link)]. The following antibodies were used: rabbit Hsp27 antibody (Assay Designs, Villeurbanne, France, 1/5000), rabbit anti-eIF4E antibody (Cell Signaling, Ozyme, 1/1000, Saint-Cyr-l’école, France), anti-rabbit IgG HRP conjugate antibody (Santa Cruz Biotechnology, Heidelberg, Germany, 1/5000), and anti-rabbit Trueblot IgG HRP conjugate antibody (eBiosciences, 1/1000, Villebon-sur-Yvette, France). Loading levels were normalized using mouse anti-vinculin antibody (Sigma-Aldrich, 1/2000, Saint-Quentin-Fallavier, France). Re-blot Plus Mild Solution (Millipore, Molsheim, France) was used for membrane stripping during 9 min at RT.
