Colon cancer cells and TLR8 Agonist Synonyms macrophage cells Following demonstrating that systemic STAT3 Activator Compound treatment with EKODE elevated colitis and tumor inflammation in vivo, we tested no matter if EKODE directly acted on colon cancer cells or immune cells to induce inflammation. To do so, we treated colon cancer (HCT-116) cells or macrophage (RAW 264.7) cells with 300 nM EKODE, then examinedinflammatory responses. We have determined the concentration of 300 nM, given that that is equivalent to the concentrations of endogenous EKODE in the colon of AOM/DSS-induced CRC mice (Fig. 2D). In HCT-116 cells, remedy with EKODE induced gene expression of pro-inflammatory cytokines (IL-6, IFN-, TNF-) after 24-h therapy, demonstrating its potent pro-inflammatory impact (Fig. 7A). Next, we tested the impact of EKODE on NF-B, which can be a vital signaling pathway involved in inflammation [14]. Just after 300 min remedy,L. Lei et al.Redox Biology 42 (2021)Fig. five. EKODE induces intestinal barrier dysfunction and increases LPS/bacterial translocation. A, LPS concentration in plasma (n = six mice per group). B, Gene expression of 16S rRNA gene in blood and spleen (n = four mice per group). C, Gene expression of Il-1, Tnf- and Il-10 in spleen (n = 4 mice per group). D, Gene expression of Occludin in colon (n = five mice per group). E, IHC staining of Occludin in colon (n = six mice per group, scale bars: 50 m). The results are imply SEM. The statistical significance of two groups was determined applying Student’s t-test or Wilcoxon-Mann-Whitney test.Fig. six. Treatment with EKODE exaggerates AOM/DSS-induced colon tumorigenesis in mice. A, Scheme of animal experiment (dose of EKODE = 1 mg/kg/day). B, Quantification of colon tumor in mice (n = eight mice per group). C, H E histology and IHC staining of PCNA and -catenin in colon (n = 8 mice per group, scale bars: 50 m). D, Gene expression of Mcp-1, Il-6, Ifn-, Pcna, Myc, Jun, Ccnd-1 and Vegf in colon (n = 8 mice per group). The results are expressed as suggests SEM. The statistical significance of two groups was determined utilizing Student’s t-test or Wilcoxon-Mann-Whitney test.L. Lei et al.Redox Biology 42 (2021)Fig. 7. EKODE induces inflammation in human colon cancer HCT-116 cells and mouse macrophage RAW 264.7 cells. The cells were treated with 300 nM EKODE or automobile (DMSO). A, EKODE increased gene expression of pro-inflammatory cytokines in HCT-116 cells following 24-h remedy (n = five per group). B, EKODE enhanced IB degradation in HCT-116 cells (n = three per group). C, EKODE improved nuclear translocation of p65 in HCT-116 cells (n = 3 per group). D, EKODE elevated gene expression of pro-inflammatory cytokines in RAW 264.7 cells soon after 24-h treatment (n = five per group). B, EKODE enhanced IB degradation in RAW 264.7 cells (n = 3 per group). C, EKODE improved nuclear translocation of p65 in RAW 264.7 cells (n = three per group). The results are imply SEM. The statistical significance of two groups was determined applying Student’s t-test or Wilcoxon-Mann-Whitney test. The cell culture experiments have been performed with at least 3 independent repeats.EKODE induced degradation of IB- and enhanced nuclear translocation of p65, demonstrating that it activated the NF-B signaling pathway (Fig. 7B ). A equivalent result was also observed in RAW 264.7 cells (Fig. 7D ). General, these final results demonstrate that therapy with EKODE, at nM doses, induced inflammatory responses and activated NF-kB pathway in each colon cancer cells and macrophage cells, illustrating its potent pro-inflammatory e.
