RETRACTION: Resistance to Chicken Amyloid Arthropathy Is Associated With a Dysfunctional Mutation in Serum Amyloid A.

C. Falker-Gieske, N.-F. Paul, M. Spourita, J.D. Gilthorpe, K. Gustmann, and J. Tetens, "Resistance to Chicken Amyloid Arthropathy Is Associated With a Dysfunctional Mutation in Serum Amyloid A," The FASEB Journal 37, no. 1 (2023): e22700, https://doi.org/10.1096/fj.202200359RR. The above article, published online on 14 December 2022 in Wiley Online Library (http://onlinelibrary.wiley.com/), has been retracted by agreement between the authors; the journal Editor-in-Chief, Loren E. Wold; and Wiley Periodicals LLC. The authors contacted the journal to request a correction, due to their discovery of a mutation in the plasmid used to generate the control LMH SAA.WT cell lines. This development led to the deletion of the C-terminal KY dipeptide and the addition of a 20 amino acid C-terminal neopeptide fusion with a different sequence than what was reported in the article. The SAA.R90S plasmid carried the correct sequence, but the perceived effects of the LMH SAA.R90S protein in cells were being compared with the incorrect control LMH SAA.WT plasmid. This error influenced the interpretation of some of the published results. The authors noted that this was an unintentional error. However, because the errors impact the study's premise and results, the article must be retracted. A revised version is forthcoming.
