Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the TRAP‐stained images shown in Fig. 1 for the 'Diabetes' and 'IGF‐I' panels contained an overlapping section, such that data which were intended to have shown the results of differently performed experiments were apparently derived from the same original source. The authors have been contacted by the Editorial Office to offer an explanation for the apparent anomaly in the presentation of the data in their paper, and we are awaiting their response. The gene discussed is IGF1; the disease is diabetes mellitus.
