The immunomodulatory effects of periostin on monocyte-derived macrophages

ABSTRACT: To explore the effects of periostin on tumor-associated macrophagess, we first sorted CD14+ monocytes from peripheral blood mononuclear cells of healthy donors using magnetic-activated cell sorting and then induced their differentiation into macrophages by culture with M-CSF for 5 days. In the absence of IL-4 stimulation, these macrophages expressed CD163 and Arg1 (a marker of M2 macrophage activation) but not CD206, suggesting that they were similar to macrophages in the early stage of mycosis fungoides (low frequency of CD206+ cells and low IL-4 expression). We then stimulated these macrophages with or without 100 ng/ml of periostin for 6 hours and examined gene expression using a cDNA microarray. Periostin stimulated gene expression on monocyte-derived macrophages was measured at 6 hours after exposure to doses of 100 ng/ml periostin.

Periostin may act on monocytes and monocyte-derived macrophages with a pro-fibrotic phenotype in patients with systemic sclerosis (SSc)

Project description:Background: Circulating periostin levels are increased in systemic sclerosis (SSc) patients and correlates positively with disease severity. Additionally, monocytes/macrophages are one of the key cells in SSc pathogenesis. However, the effect of periostin on immune cells, particularly monocytes and macrophages, has not been well investigated. Objectives: To examine the effect of periostin on monocytes and monocyte-derived macrophages (MDMs) in SSc. Methods: Monocytes were purified from blood samples of nine diffuse cutaneous SSc patients and five healthy controls (HCs) and were differentiated into macrophages. Cell surface markers were assessed by flow cytometry. RNA sequencing analysis was performed on recombinant periostin-stimulated monocytes from three HCs. Cytokine/chemokine and extracellular matrix (ECM) protein expressions in MDMs differentiated supplemented with recombinant periostin were assessed by quantitative real-time polymerase chain reaction and bead-based immunoassays in six HCs. Moreover, we evaluated whether periostin was involved in monocyte migration by Transwell assay. Results: The modified Rodnan total skin thickness score correlated positively with the proportion of CD80-CD206+ M2 cells. The M2 macrophage proportion was reduced in rPn-stimulated MDMs in HCs, but not in SSc patients. mRNA expression levels of pro-fibrotic cytokine, chemokine, and ECM protein genes were significantly upregulated in recombinant periostin-stimulated monocytes and MDMs as compared to those from control monocytes and MDMs. Similar trends for their protein levels were also observed in MDMs. Moreover, the ratio of migrated cells in recombinant periostin-stimulated monocytes was significantly higher than that in control monocytes.

Gene Expression Analysis in Different Macrophage Phenotypes

Project description:Macrophage activation is the main immunological process occurring during the development of several diseases, and the heterogeneity of macrophage activation or differentiation has been suggested to be involved in disease progression. In the present study, we attempted to identify molecules specifically expressed on human classically activated macrophages (M1) to investigate the significance of the M1-like phenotype in human diseases. Human monocyte-derived macrophages were differentiated into M1, M2a, M2b, and M2c phenotypes, and gene expression profiles were analyzed by cDNA microarray analysis and were used for bioinformatics examination. The gene expression profiles of murine macrophages were additionally evaluated. We identified guanylate-binding protein 5 (GBP5), which is associated with leucine-rich repeat protein 3-mediated inflammasome assembly in the M1 macrophages of both humans and mice. Notably, GBP5 protein expression was detected in cultured M1 macrophages by Western blot analysis. GBP5 is a useful candidate marker of the M1 phenotype. CD14+ monocytes from human PBMC were cultured with GM-CSF(10 ng mLâ1) or M-CSF (50 ng mLâ1) for seven days to differentiate into macrophages.To induce macrophage subtypes [M1, M1(-), M2a, M2b, and M2c], the macrophages were further stimulated for 24 h with LPS (10 ng mLâ1) + IFN-Î³ (50 ng mLâ1), IFN-Î³ (50 ng mLâ1), IL-4 (10 ng mLâ1), IL-1Î² (10 ng mLâ1), and IL-10 (10 ng mLâ1). Control macrophages (M0) were prepared by incubating for 24 h without additional factors.Two independent experiments were performed using different donors.

Periostin cooperates with mutant p53 to mediate invasion

Project description:Periostin, a matricellular protein, has been reported to be important in supporting tumor cell dissemination. However, the molecular mechanisms underlying periostin function within the tumor microenvironment are poorly understood. In this study, we observe that loss of periostin decreases esophageal squamous cell carcinoma (ESCC) tumor growth in vivo and demonstrate that periostin cooperates with a conformational missense p53 mutation to enhance invasion. Pathway analyses reveal that invasive esophageal cells expressing periostin and p53R175H mutation display activation of signal transducer and activator of transcription 1 (STAT1) target genes, suggesting that the induction of STAT1 and STAT1-related genes could foster a permissive microenvironment that facilitates invasion of esophageal epithelial cells into the extracellular matrix (ECM). Genetic knockdown of STAT1 in transformed esophageal epithelial cells underscores the importance of STAT1 in promoting invasion and potentiate tumor resistance to genotoxic stress. Furthermore, we find that STAT1 is activated in ESCC xenograft tumors but this activation is attenuated with inducible knockdown of periostin in ESCC tumors. Overall, these results highlight the molecular mechanisms supporting the capacity of periostin in mediating tumor invasion during ESCC development.

Periostin Upregulated in Cancer-Associated Fibroblasts upon Direct Contact with Cancer Cells Promotes Esophageal Squamous Cell Carcinoma Progression by Enhancing the Migration of Cancer Cells and Stromal Cells

Project description:Cancer-associated fibroblasts (CAFs) in the tumor microenvironment are involved in the progression of esophageal squamous cell carcinoma (ESCC). We generated CAF-like cells by direct co-culture of human bone marrow-derived mesenchymal stem cells (MSCs), one of the origins of CAFs, with ESCC cell lines and found that periostin is highly expressed in CAF-like cells. Periostin activated Akt and Erk signaling pathways in ESCC cells, enhancing survival and migration via integrin β4, one of the receptors for periostin. Periostin also enhanced migration of MSCs and macrophages and caused macrophages to acquire tumor-associated macrophage (TAM)-like properties. High periostin expression in cancer stroma was associated with several clinicopathological factors and expressions of CAF markers and numbers of infiltrating TAMs. Moreover, ESCC patients with high periostin expression exhibited significantly poor postoperative outcomes. Thus, periostin secreted from CAFs enhanced the migration of ESCC cells, MSCs, and macrophages and contributed to developing the tumor microenvironment. These results indicate that periostin may be a novel therapeutic target for ESCC.

Periosteum contains skeletal stem cells with high bone regenerative potential controlled by Periostin

Project description:Bone regeneration relies on the activation of skeletal stem cells (SSCs) that still remain poorly characterized. Here, we show that periosteum contains SSCs with high bone regenerative potential compared to bone marrow stromal cells/skeletal stem cells (BMSCs) in mice. Although periosteal cells (PCs) and BMSCs are derived from a common embryonic mesenchymal lineage, post-natally PCs exhibit greater clonogenicity, growth and differentiation capacity than BMSCs. During bone repair, PCs can efficiently contribute to cartilage and bone, and integrate long-term after transplantation. Molecular profiling uncovers genes encoding Periostin and other extracellular matrix molecules associated with the enhanced response to injury of PCs. Periostin gene deletion impairs PC functions and fracture consolidation. Periostin-deficient periosteum cannot reconstitute a pool of PCs after injury demonstrating the presence of SSCs within periosteum and the requirement of Periostin in maintaining this pool. Overall our results highlight the importance of analyzing periosteum and PCs to understand bone phenotypes.

Emodin inhibits macrophage alernative activation [Control-IL4-Emodin]

Project description:In order to fully characterize emodin's effects on macrophage alternative activation, peritoneal macrophages were stimulated with IL4 with or without emodin and gene expression was analyzed using a whole genome microarray. Emodin significantly attenuated the IL4 induced changes in a large percentage of genes (60%) through inhibiting multiple signaling pathways. RT-qPCR was used to confirm the results in several genes associated with M2 macrophage activation including: Arg1, Chi3l3, and CD206. Three-condition, one-color experiment: Vehicle control, IL4 or IL4-Emodin treated periferal WBC PMN samples: 4 biological replicates each.
