IL-23 Decreased the Integrity of Tumor Epithelial Tight Junction DCs generated from THP-1 monocytes were confirmed by both morphology plus the The epithelial barrier integrity loss potentially contributes to colon tumorigenesis. expression of DC-sign marker by immunofluorescence staining (Figure 3A). DCs represent Claudins group of immune cells that display twodysregulation has been shown to moduare tight junctional proteins and their various phenotypes as pro-tumorigenic a unique late barrier permeability, inflammation, and tumorigenesis within the gastrointestinalCD83and anti-tumorigenic determined by their phenotype maturation ligands (CD80-high, tractCancers 2021, 13,9 ofhigh) plus the expression of IL-23 [24,25]. The expression of IL-23 (IL-23+) inside a DC, in addition to the higher expression of phenotype maturation ligands, represents pro-tumorigenic phenotype which is involved in cancer progression and immune-suppression as in comparison with IL-23 damaging (IL-23-) phenotype [24]. We analyzed the possible correlation between IL23A with pro-tumorigenic DC marker gene expressions applying the TCGA-COAD RNA-seq database. The dataset revealed that elevated IL-23A expression was positively correlated with CD80 and CD83 (Figure 3B). In this study, we investigated irrespective of whether obesity-associated pro-inflammatory molecules and microbial toxins can polarize DCs into a pro-tumorigenic phenotype. We observed that the treatment of AA, PGE2 , LTA, and LPS induces myeloidderived DCs into a pro-tumorigenic DC phenotype together with the expression of CD80-high, CD83-high, and enhanced IL-23 levels compared to vehicle-treated DCs using the expression of CD80-low, CD83-low, and low IL-23 level (Figure 3C,D; Figures S4A and S11). three.six. Effect of AA, PGE2, and Bacterial Toxins on IL-23 Production in Macrophages Macrophages generated from THP-1 monocytes and have been confirmed by morphological appearance at the same time as by the expression of macrophage markers (IL-1, CD163) (Figures 3E and S11). Macrophages according to their microenvironment is usually converted into tumor-associated macrophages (TAMs), which have served as a paradigm for the connection among inflammation and cancer [26]. TAM influences all aspects of tumor growth and progression [27]. Cytokines play a essential role in the tumor-promoting functions of.
