Two faces of polarized macrophages: differential effects of M1 and M2 macrophage subtypes on lung cancer progression

ABSTRACT: Macrophages in tumor microenvironment have been characterized as M1- and M2-polarized subtypes. This study sought to investigate the effects of different macrophage subtypes on the biological behavior and global gene expression profiles of lung cancer cells. Expression microarray and bioinformatics analyses indicated that the different macrophage subtypes mainly regulated genes involved in cell cycle, cytoskeletal remodeling, coagulation, cell adhesion and apoptosis pathways in A549 cells, a pattern that correlated with the altered behavior of A549 cells observed after coculture with macrophage subtypes. We used microarrays to identify the global gene alterations in lung cancer cells A549 after culture in conditioned media from different subtype macrophages.

Genome-wide analysis of M1 and M2 polarized macrophages with CNI-1493 treatment

Project description:Analysis of the effects of CNI-1493 treatment on M1 and M2 polarized macrophages. The purpose of this microarray is to identify genes that may be differentially expressed in M1 or M2 macrophages after treatment with CNI-1493. CNI-1493 is a known inhibitor of M1 macrophages but details of its molecular mechanism are unknown. The effect of CNI-1493 on M2 macrophages has yet to be explored, but we hypothesize that CNI-1493 treatment will attenuate pro-tumor properties of M2 macrophages. We demonstrate with this array that known macrophage markers are unchanged after treatment with CNI-1493, indicating that CNI-1493 does not change the macrophage phenotype on a transcriptional level. Additionally, no candidate genes to suggest how CNI-1493 may attenuate the pro-tumor effects of M2 macrophages are readily identifiable. Total RNA extracted from M1 or M2 macrophages after polarization with GM-CSF (25ng/ml) or M-CSF (25ng/ml) for 7 days, followed by addition of IFN-γ (20ng/ml) and LPS (100ng/ml) or IL-4 (40ng/ml) for 18 hours, respectively, from CD14+ human PBMCs, and treated with CNI-1493 (200nM)

Differentially polarized human monocyte-derived macrophages (M0, M1, M2/IL10, M2/IL4, TAM-like)

Project description:In order to assess whether differences in the transcriptomic profile of human tumor-associated macrophages vs. alveolar macrophages from adjacent non-tumor-tissue (GSE162669) were caused by factors secreted by tumor cells, primary human monocyte-derived macrophages (MDMs) were polarized towards a TAM-like phenotype by cultivating them in tumor cell-conditioned medium. A genome-wide comparison by bulk RNA-Seq confirmed a high similarity of ex vivo TAMs and in vitro polarized TAM-like macrophages. Other polarization schemes (M1: LPS/IFN-gamma, M2: IL10 or IL4) did not lead to similar transcriptomic changes. For details, see Hoppstädter et al., 2021 (doi:10.1016/j.ebiom.2021.103578).

MiR expression profiles in M1-polarized compared with unstimulated (MÐ¤) bone marrow-derived macrophage cells

Project description:The global change of the miR expression profile during atherosclerosis is due to the infiltration of different types of leukocytes into the arterial vessel wall in addition to disease-specific regulation in vascular cells. Monocyte-derived macrophage accumulation in the subintimal region is critical in the formation of atherosclerotic plaques. It is currently unknown which miRs are involved in the atherogenic macrophage response. The comparison of the miR expression profile in LPS/Interferon-gamma activated mouse macrophages with the miR expression in the unstimulated mouse macrophages was performed to detect M1-type macrophage-enriched miRs. This screening combined with our miR profiling in atherosclerotic vessels may help to identify M1-type macrophage-enriched miRs in atherosclerotic vessels that may play a role in the macrophage function during atherogenesis. Bone marrow cells were harvested from femura of 6- to 8-week-old female C57BL/6 mice, re-suspended in DMEM-F12/10% FCS/10% L929-conditioned medium, and cultured for 7 days to differentiate into primary macrophages. F4/80 and CD11b expression was determined by flow cytometry to confirm the macrophage phenotype. Macrophages were stimulated with LPS (100ng/ml, 14 hours) and INF-g (10ng/ml, 6 hours), and the M1 polarization was verified by quantification of mannose receptor C type 1 (MRC1), arginase II (ArgII), inducible nitric oxide synthase (iNOS), and arginase I (ArgI) by qRT-PCR. Total RNA (M1-type and unstimulated (MÐ¤) macrophages) was isolated using the mirVana microRNA Isolation Kit.

Gene expression data from murine M1 and M2 macrophages

Project description:Macrophages have distinct characteristics depending on their microenvironment. We performed proteomic analysis between M1 and M2 macrophages and found that cellular metabolism is the key regulator of macrophage function. We used microarray to support proteomic data between M1 and M2 macrophages. M1 macrophages are obtained using cell sorting of CD45+MHCII+CD8a-F4/80+ population from C57BL/6J bone marrow cell derived heterogenous cells under GM-CSF conditioning for 7 days. M2 macrophages are differentiated with 20% L929 cell supernatant for 7 days and sorted from CD45+F4/80+CD11b+ population.

Glycoproteomics of human THP-1-derived M0, M1 and M2 macrophages

Project description:In this study, we used human THP-1-derived macrophages as an immune cell model, and systematically performed glycoproteomics of three subtypes of macrophages by StrucGP.To study the N‑Glycoproteomic of them, the intact glycopeptides were first enriched and identified using triplicate mass spectrometry (MS)-based glycoproteomic approaches, then StrucGP was used for subsequent analysis. In total three subtypes of macrophages, these intact glycopeptides consist of 253 N-linked glycan structures at 652 unique glycosites from 372 N-glycoproteins, along with their PSM information. A total of 135, 163, and 201 N-glycan structures were identified from M0, M1, and M2 macrophages, respectively.

Identification of downregulated microRNA in a gastric cancer cell line co-cultured with M1- or M2-polarized macrophage

Project description:We showed that co-culture with TAMs triggered Bmi1 expression in gastrointestinal cancer cell lines. miRNAs have been found to target various oncogenes and tumor suppressors. We therefore hypothesized that the regulation of Bmi1 expression in gastrointestinal cancer cells may be mediated by miRNAs using miRNA microarray analysis. THP-1 cells were seeded in the transwell inserts (3540, Corning) for 6-well plates (1 M-CM-^W 106 cells/well). For preparation of M1-polarized THP-1 macrophages, 320 nM phorbol myristate acetate (PMA) was added to THP-1 cells for 6 h, followed by PMA plus 20 ng/ml interferon (IFN)-M-NM-3 and 100 ng/ml lipopolysaccharide for the following 18 h. For preparation of M2-polarized THP-1 macrophages, 320 nM PMA was added to THP-1 cells for 6 h, followed by PMA plus 20 ng/ml interleukin (IL)-4/IL-13 for the following 18 h. After three washes to remove cytokines, M1- or M2-polarized THP-1 macrophages were co-cultured in upper inserts with AGS cells in 6-well plates (1 M-CM-^W 105 cells/well) without direct contact, in each medium without 10% FBS as described above. After 24 h of co-culture, the upper inserts containing macrophages were discarded. AGS cells were collected and analyzed to identify downregulated microRNA in a gastric cancer cell line co-cultured with M1- or M2-polarized macrophage.

Gene expression profiles from murine BALB/c macrophages at the extremes of the M1 and M2 polarized phenotypes

Project description:Macrophages possess the hallmark feature of plasticity, allowing them to undergo a dynamic transition between M1 and M2 polarized phenotypes. The aim of the present study was to screen for differentially expressed genes (DEGs) that were associated with macrophage polarization. The transcription profiles of three M1 and three M2 samples were obtained using microarray analysis. Based on the threshold of fold-change >2.0 and a p-value < 0.05, we screened a total of 1,253 DEGs, of which 696 were upregulated and 557 downregulated in M1 macrophages compared to that in M2 macrophages. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were also performed. A gene-gene interaction network of the DEGs was constructed using the STRING database. GO annotation identified three categories, which included cellular component (CC), molecular function (MF), and biological process (BP), with 34 and 40 enrichment terms consisting of upregulated and downregulated DEGs, respectively. GO enrichment analysis of DEGs was mainly associated with protein binding, response to stimulus, cell differentiation, and regulation of biological process. KEGG enrichment identified 15 and four pathways involving upregulated and downregulated DEGs, respectively. Signaling pathway analysis showed that these DEGs were mainly involved in apoptosis, HIF-1 signaling pathway, innate immune system, TNF signaling pathway, cytokine-cytokine receptor interaction, and other signal transduction pathways. Interaction network analysis indicated that Tnf, Il6, Il1b, Socs3, Nos2, Hif1a, and other genes may play key roles in macrophage polarization. This study provides new insights into the role of genes in macrophage differentiation and polarization.
