mRNA profiling of monocytes derived macrophages and PDAC cell lines supernants-induced tumor-associated macrophages (TAMs)

Project description:Tumor associated macrophages have been demonstrated to promote tumor progression, but the mechanism is still unclear. We found the gene expression of monocytes derived macrophages is different from TAMs by comparing mRNA profiling.

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.

Expression data from in vitro-induced non-hypoxic tumour associated macrophages (TAMs)

Project description:Active immunotherapy is a promising strategy for anti-angiogenic cancer therapy. Recently, we have reported that a vaccine using human umbilical vein endothelial cells (HUVECs) induced specific anti-endothelial immune responses in the most of immunized patients, and resulted in tumor regression in some patients with recurrent malignant brain tumors, whereas not in colorectal cancer patients. In this study, we hypothesized that non-hypoxic perivascular tumor associated macrophages (TAMs) in colorectal cancer, but not in glioblastoma, might negatively alter the therapeutic efficacy of anti-angiogenic active immunotherapy. To test this hypothesis, we examined global gene expression profiles of non-hypoxic macrophages stimulated in vitro by soluble factors released from tumor cells of human glioblastoma U-87MG (‘brain TAMs’) or colorectal adenocarcinoma HT-29 (‘colon TAMs’). Murine non-hypoxic TAMs were induced in vitro by incubation with soluble factors released from human cancer cell lines U-87MG ('brain TAMs') or HT-29 ('colon TAMs'), for RNA extraction and subsequent hybridization on Affymetrix microarrays. To evaluate homogeneous macrophage populations at different tumour developmental stages, RNA aliquots of control macrophages and TAMs obtained at five different time-points, i.e. 8h, 16h, 24h, 32h and 40h, were pooled and used for screening of differentially expressed genes. The experiments for TAMs as well as for control unstimulated macrophages were performed in triplicates.

Increased pro-inflammatory phenotype of peripheral blood monocytes and monocyte-derived macrophages among patients with excessive ethanol intake

Project description:Excessive alcohol consumption adversely affects the immune system and triggers the activation of peripheral blood (PB) monocytes and tissue macrophages, contributing to alcohol- related organ damage. This study aimed to analyze the M1/M2 and inflammatory phenotypes of circulating monocytes and macrophage-derived monocytes (MDMs). This single-center cross- sectional study included 20 excessive alcohol drinkers (EADs) and 22 healthy controls. PB samples were collected under fasting conditions for isolation of CD14+ monocytes and short-term culture without stimulation, LPS/IFNγ, or IL4/IL13. These conditions were also used to polarize monocyte-derived macrophages (MDMs) into M0, M1, or M2 phenotypes. Cytokine production was assessed in the blood samples and supernatants. M1/M2 related markers in PB monocytes and MDMs were analyzed using mRNA expression and surface marker analyses. In addition, the miRNA profile was analyzed in CD14+ monocytes. PB samples from EADs exhibited increased levels of pro-inflammatory cytokines.

mRNA profiling of schwann cells cultured with monocytes derived macrophages and PDAC cell lines supernants-induced tumor-associated macrophages (TAMs)

Project description:Tumor associated macrophages(TAMs) have been demonstrated to promote tumor progression and perineural invasion in PDAC, however the underlying machanism of TAMs interacting with Schwann cells is still unclear. We found the gene expression of Schwann cell is different from TAMs-induced Schwann cells by comparing mRNA profiling.

Gene expression profiles of tumor-associated macrophages (TAMs) overexpressing miR-511-3p

Project description:Hematopoietic stem/progenitor cells (HS/PCs) were transduced with lentiviral vectors overexpressing OFP and either miR-511-3p or a control, mutated miRNA sequence (miR-511-3p-mut). The transduced HS/PCs were then transplanted in recipient C57BL/6 mice. Tumors (Lewis lung carcinomas, LLC) were injected s.c. 4 weeks after HS/PC transplant. Lentiviral vector-transduced (OFP+), tumor-associated macrophages (TAMs) were isolated 4 weeks after LLC injection by fluorescence-activated cell sorting. Gene expression profiles of TAMs overexpressing either miR-511-3p or miR-511-3p-mut were obtained from 3 independent biological samples/each. Gene expression profiles of miRNA-overexpressing TAMs were then compared with the gene expression profiles of wild-type TAMs isolated from LLCs grown in nontransplanted C57BL/6 mice; the latter TAMs were subfractioned into MRC1+CD11c(low) or CD11c+MRC1(low) subsets before RNA isolation and analysis. Comparison of gene expression profiles of TAMs revealed that miR-511-3p overexpression tunes down the expression of multiple genes that are classically upregulated in protumoral MRC1+CD11c(low) TAMs. TAMs were isolated from Lewis lung carcinomas grown s.c. in C57BL/6 mice.
