IL-23 Decreased the Integrity of Tumor Epithelial Tight Junction DCs generated from THP-1 monocytes have been confirmed by both morphology as well as 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 Avasimibe medchemexpress twodysregulation has been shown to moduare tight junctional proteins and their unique phenotypes as pro-tumorigenic a particular late barrier permeability, inflammation, and tumorigenesis in the gastrointestinalCD83and anti-tumorigenic according to 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+) in a DC, together with the higher expression of phenotype maturation ligands, represents pro-tumorigenic phenotype which can be involved in cancer progression and immune-suppression as compared to IL-23 damaging (IL-23-) phenotype [24]. We analyzed the prospective correlation involving IL23A with pro-tumorigenic DC marker gene expressions utilizing 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 regardless 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 with all the expression of CD80-high, CD83-high, and enhanced IL-23 levels when compared with vehicle-treated DCs with all the expression of CD80-low, CD83-low, and low IL-23 level (Figure 3C,D; Figures S4A and S11). 3.6. Impact of AA, PGE2, and Bacterial Toxins on IL-23 Production in Macrophages Macrophages generated from THP-1 monocytes and were confirmed by morphological appearance too as by the expression of macrophage markers (IL-1, CD163) (Figures 3E and S11). Macrophages depending on their microenvironment can be converted into tumor-associated macrophages (TAMs), which have served as a paradigm for the connection in between inflammation and cancer [26]. TAM influences all aspects of tumor development and progression [27]. Cytokines play a important part inside the tumor-promoting functions of.
