After this article [1] was published, concerns were raised that in Fig 1, the CRABP1 and CRBP2 panels appear similar, when levels are adjusted to visualize the background.
The corresponding author (KL) stated that the original image data underlying the published panels are unavailable; as such, this issue cannot be resolved. However, PLOS concluded that the article’s overall results and conclusions are not significantly affected, since the panels of concern present negative results and subsequent results relate to CRABP2.
The PLOS One Editors issue this Editorial Note to inform readers of this unresolved concern.
