In addition, the Fig 2D NFATc1 panel was found to appear similar to a Fig 3B NFATc1 panel in another published article, despite being used to represent different experimental conditions. More extensive overlaps were identified between Fig 5 of the retracted paper and Fig 4 of a separate publication. The Editors report that Fig 5a and Fig 4a appear to partially overlap when flipped, Fig 5b matches Fig 4b, Fig 5c overlaps Fig 4d when flipped, and Fig 5e and Fig 5f each overlap their Fig 4 counterparts.

Within the retracted article itself, Figs 5i and 5k also appear to partially overlap, again despite representing different experimental conditions. The Editors state that all authors either did not respond directly or could not be reached regarding the concerns. The retraction notice was published on October 19, 2026, and is associated with the DOI 10.1371/journal.pone.0360868.
