The editors were made aware of concerns by a reader regarding potential manipulation of data in this article (1). An internal review by the editors determined that lanes 2–4 of the β-actin Western blot image in Fig. 2C (MC26 cells) were rotated and duplicated in lanes 2–4 of the β-actin Western blot image in Fig. 2D. The editors are publishing this note to alert readers to these concerns.
