The Editor has retracted this article [1] following an investigation by the University of South Alabama which found:

• The same Western blot images were used for Caspase-7 (Fig. 4C) and AKT (Ser473, MT + I) (Fig. 7)

• In Fig. 4D, the 6 h band for MT was replicated, the image was then inverted and the band was used for the 36 h time point

• In Fig. 7, the same Western blot image was used to demonstrate responses in MT + I for PDK-1 (P-Ser241) and P-GSK-3beta

• In Fig. 7, the blot for P-FKHR-L1 at time point 0 was replicated and used for the 24 h time point
