Figure Legend Snippet: S100A8/A9 hi macrophages mediate CCL6 expression through activation of the transcription factor STAT3. (A) Venn diagram integrating multiple bioinformatic databases to identify potential upstream transcription factors regulating Ccl6 expression. (B) Protein‐protein interaction network between the nine transcription factors and S100A9. (C–F) BMDMs were stimulated with recombinant S100A8‐S100A9 protein (1 µg/mL) with or without pretreated with FPS‐ZM1 (1 µ m ), TAK‐242 (1 µ m ) or DMSO vehicle for 1 h. p‐STAT3 and total STAT3 were assessed by Western blot at 2 h (C and D), and CCL6 levels in culture supernatants were measured by ELISA at 24 h (E). The colocalization of S100A8/A9 with TLR4 in BMDMs was assessed by immunofluorescence staining (F); Scale bar, 20 µm. (G,H) Following pretreatment with or without Stattic (5 µ m ) for 1 h, BMDMs were stimulated with recombinant S100A8‐S100A9 protein (1 µg/mL). p‐STAT3 and total STAT3 levels were assessed by Western blot at 2 h (G), and CCL6 in culture supernatants was quantified by ELISA at 24 h (H). (I,J) BMDMs were transfected with siNC or si S100a9 , followed by treatment with Colivelin TFA (50 µg/mL) for 4 h to activate STAT3. Protein levels of S100A9, p‐STAT3/STAT3, and CCL6 were measured by Western blot (I), and p‐STAT3 expression was visualized by immunofluorescence (J; Scale bar: 500 µm). (K) Western blot analysis of p‐STAT3 levels in nuclear and cytoplasmic fractions of BMDMs transfected with siNC or siS100a9 . (L) Schematic representation of putative STAT3 binding sites within the Ccl6 promoter. (M) Dual‐luciferase reporter assays were performed in HEK 293T cells co‐transfected with a control vector (NC) or a Stat3 expression plasmid, together with reporter vectors pGL1‐Control, pGL1‐Ccl6 wild‐type (WT), or pGL1‐Ccl6 mutant (mut). Promoter activity was measured and normalized. N, O) BMDMs were treated with recombinant S100A8‐S100A9 protein (1 µg/mL) for 2 h. STAT3 recruitment to the Ccl6 promoter was analyzed by chromatin immunoprecipitation (ChIP) assay. The enrichment of p‐STAT3 at the promoter region was quantified by RT‐qPCR and expressed as a percentage of the total input (N). Representative agarose gel images confirmed the specificity of the PCR amplification (O). All values are expressed as mean ± SD. ns, no significant difference, * p < 0.05, ** p < 0.01, *** p < 0.001.
