VOLUME 287 (2012) PAGES 12016–12026
The authors have identified two errors and two areas that needed clarification in this article.
PAGE 12020:
In the corrected Fig. 2A, dotted lines have been added to the immunoblots showing GSK3β and ERK phosphorylation to indicate areas of vertical splicing. All spliced images were from a single immunoblot; only the order was changed to have a consistent order among all cell lines.
PAGE 12021:
In the corrected Fig. 3A, dotted lines have been added to indicate the borders of different sections of the same immunoblot. Additionally, in the original figure, the actin controls were upside down compared with the original immunoblots. For clarity, this inversion has now been corrected.
PAGE 12022:
In the original Fig. 5A, the wrong LRP5 and LRP6 immunoblots were inadvertently inserted during assembly of the figure. This error has now been corrected in the corrected Fig. 5A.
None of these errors affect the results or conclusions of this work. We apologize for any confusion that these changes may have created.
