Description

A 2026 expression of concern flags figure problems in a study of constipation in a mouse model of Alzheimer's disease. Several image panels across five figures appear similar to panels in other figures or other papers, and one blot shows splice marks. The corresponding author stated that some panels are incorrect and supplied corrected figures from the original experiments. Shared control images and a two-gel layout were offered as explanations for other overlaps. The notice links the original images for reader review.
