Following the publication of this article [1], concerns were raised regarding results presented in Figs 1 and 5. Specifically, when levels are adjusted to visualize the background:
The corresponding author provided additional methodological information to explain the appearance of vertical discontinuities:
The corresponding author provided the available uncropped underlying images for this article (S3–S7 Files) including the Dog and Fox panels of Fig 1B, and the Dog LJL23 panel of Fig 5, but they were unable to retrieve all original images for the figures included in the article.
In evaluating the “-” lane of the Dog panel of Fig 1B, PLOS noted some differences between the published figure and the underlying blot image. Although this issue was not resolved, PLOS concluded that the data provided for Figs 1B and 5 appear to support the results reported in [1].

S2 FileExample of a scanned underlying image showing a multiscreen apparatus blot.This is a scanned image of a multiscreen apparatus blot from an experiment unrelated to this article, provided to show the discontinuity in background seen in blots used in this methodology. Once scanned, the image appears flat and the negative lane appears similar to the blank background.(JPG)
