Retraction Statement

The article "IRF9 Affects the TNF-Induced Phenotype of Rheumatoid-Arthritis Fibroblast-Like Synoviocytes via Regulation of the SIRT-1/NF-κB Signaling Pathway" [Cells Tissues Organs. 2020;209(2-3):110-119; https://doi.org/10.1159/000508405] by Fan Jiang, Hong-Yi Zhou, Li-Fang Zhou, Wei Zeng, and Li-Han Zhao has been retracted by the Publisher and the Editors.After publication of this article, concerns were raised about the integrity of the data presented in Figure 1. Specifically, panels in Figure 1c had previously been published by different author groups representing different experimental conditions.Figure 1c "control" panel is the same as Figure 3b panel "Anti-miR-C FITC-A" in [1], Figure 3b panel "NC siRNA" [2], and Figure 3a panel "SNORD44" in [3].Figure 1c "TNF" panel is the same as Figure 3a panel "Anti-miR-C" in [1].Figure 1c "TNF + sh-Ctrl" panel is the same as Figure 3a panel "Anti-miR-186" in [1] and Figure 3b panel "empty vector" in [3].Figure 1c "sh-IRF9" panel is the same as Figure 3b panel "miR-C FITC-A" in [1] and Figure 3b panel "blank" in [2].Figure 1c "TNF + sh-IRF9" panel is the same as Figure 3d panel "Anti-miR-186 FITC-A" in [1].Figure 1c "TNF + sh-SIRT1" panel is the same as Figure 3a panel "miR-C FITC-A" in [1] and Figure 3a panel "control" in [3].Figure 1c "TNF + sh-IRF9 + sh-SIRT1" panel is the same as Figure 3a panel "miR-186 FITC-A" in [1] and Figure 3a panel "empty vector" in [3].The authors did not respond to requests to comment on the concerns and provide the raw data within the given timeframe despite multiple attempts of contact. The matter was raised to the corresponding author's institution who did not respond to our request for an investigation. Given the severity of the concerns raised, this article is being retracted. The authors have not responded to our correspondence regarding this retraction despite multiple attempts of contact.
