IL-23 Decreased the Integrity of Tumor Epithelial Tight Junction DCs generated from THP-1 monocytes were confirmed by each 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 show twodysregulation has been shown to moduare tight junctional proteins and their different phenotypes as pro-tumorigenic a particular late barrier permeability, inflammation, and tumorigenesis inside the gastrointestinalCD83and anti-tumorigenic based on their phenotype maturation ligands (CD80-high, tractCancers 2021, 13,9 ofhigh) and also the expression of IL-23 [24,25]. The expression of IL-23 (IL-23+) within a DC, in conjunction with the higher expression of phenotype maturation ligands, represents pro-tumorigenic phenotype which can be involved in cancer progression and immune-suppression as when compared with IL-23 adverse (IL-23-) phenotype [24]. We analyzed the potential correlation involving IL23A with pro-tumorigenic DC marker gene expressions making use of 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 whether obesity-associated pro-inflammatory molecules and microbial toxins can polarize DCs into a pro-tumorigenic phenotype. We observed that the remedy of AA, PGE2 , LTA, and LPS induces myeloidderived DCs into a pro-tumorigenic DC phenotype using the expression of CD80-high, CD83-high, and increased IL-23 levels when compared with vehicle-treated DCs with the expression of CD80-low, CD83-low, and low IL-23 level (Figure 3C,D; Figures S4A and S11). 3.6. 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 look also as by the expression of macrophage markers (IL-1, CD163) (Figures 3E and S11). Macrophages according to their microenvironment is often converted into tumor-associated macrophages (TAMs), which have served as a paradigm for the connection in between inflammation and cancer [26]. TAM influences all elements of tumor growth and progression [27]. Cytokines play a crucial role in the tumor-promoting functions of.
