Retraction: Interleukin-6 Synthesis in Human Chondrocytes Is Regulated via the Antagonistic Actions of Prostaglandin (PG)E2 and 15-deoxy-Δ12,14-PGJ2.

This article, titled "Retraction: Interleukin-6 Synthesis in Human Chondrocytes Is Regulated via the Antagonistic Actions of Prostaglandin (PGE2) and 15-deoxy-Δ12,14-PGJ2," was retracted due to concerns raised about several figures. The concerns revolve around similarities between certain lanes and panels in the figures, indicating potential image manipulation. The corresponding author was unable to provide the underlying data to address these concerns. As a result, the editors of PLOS ONE decided to retract the article. The retraction decision was supported by one of the authors, while the other authors did not respond or could not be reached. It should be noted that some panels in the article were previously published and may not have been offered under a CC-BY 4.0 license. [Extracted from the article]
