Subsequently to the publication of this article, the authors have realized that Fig. 4 contained some incorrectly incorporated data panels; specifically, the A-d, B-b and B-c panels did not display the correct data. The revised version of Fig. 4 featuring the correct data for the A-d, B-b and B-c panels is shown on the next page.

Note that these errors did not affect the overall conclusions reported in the paper. The authors apologize to the Editor of Molecular Medicine Reports and to readership for any inconvenience caused.
