This Expression of Concern relates to the article ‘Suppression of intestinal tumorigenesis in Apc mutant mice upon Musashi-1 deletion’ by Andy R. Wolfe, Amanda Ernlund, William McGuinness, Carl Lehmann, Kaitlyn Carl, Nicole Balmaceda and Kristi L. Neufeld (2017). J. Cell Sci.130, 805-813 (doi: 10.1242/jcs.197574).

We have recently been made aware of concerns regarding some of the data in Fig. 2A and B, and Fig. 3A. After discussion with the corresponding author, Kristi Neufeld, this matter has been referred to the authors’ institute. Journal of Cell Science is publishing this note to make readers aware of the issue, and we will provide further information once it has been resolved.

This course of action follows the advice set out by COPE (Committee on Publication Ethics), of which Journal of Cell Science is a member.
