TMT-based quantitative proteomics analysis of PSMα3-treated THP-1 derived macrophages

ABSTRACT: This study employed tandem mass tag (TMT) quantitative proteomics to investigate the dose-dependent effects of Staphylococcus aureus virulence factor phenol-soluble modulin α3 (PSMα3) on the global protein expression profile of human macrophages. THP-1 monocytic cells were differentiated into macrophages using PMA and then treated with 0 (control), 1, or 3 μM PSMα3 for 24 hours. Cellular proteins were extracted, digested, labeled with TMT reagents, and analyzed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) on an Orbitrap Exploris 480 platform. The dataset aims to identify proteins and pathways significantly altered by PSMα3 exposure, providing insights into the molecular mechanisms underlying macrophage responses to staphylococcal infection and potential targets for therapeutic intervention.

Analysis of mixed-oxysterol treatment on the THP-1 macrophage

Project description:THP-1 monocytes were differentiated, via PMA treatment, to macrophages. THP-1 macrophages were then treated with a mixed-oxysterol treatment (7-ketocholesterol and 7beta-hydroxycholesterol) for 24 hours. The mixed-oxysterol treatment was mixed to a ratio that represents the cytotoxic oxysterol content of human atherosclerotic plaque. Control and treated macrophages were analysed using both 2-DE with peptide mass-fingerprinting and tandem-mass spectrometry.

Dose-dependent phorbol 12-myristate-13-acetate mediated monocyte-to-macrophage differentiation induces unique proteomic signatures in THP1 cells

Project description:Macrophages are sentinels of the immune system and THP1 monocytic cells are one of the widely used models to study immune responses in macrophages. Several monocyte-to-macrophage differentiation protocols exist with phorbol 12-myristate-13-acetate (PMA) being widely used and accepted. However, the concentrations and durations of PMA treatment to induce differentiation varies widely in published literature. In this study, we determined the proteome expression dynamics of THP1 macrophages differentiated from monocytes by three commonly used PMA-based differentiation protocols using dimethyl labeling-based quantitative proteomics analysis. Our analysis shows that variations in PMA concentration and varying periods of rest post-stimulation result in downstream differences in proteome expression and cellular processes. We demonstrate that these differences result in altered expression of cytokines upon stimulation with different TLR ligands. Together, these findings provide a valuable resource that significantly expands the knowledge of protein expression dynamics in in vitro models of macrophages which in turn has profound impact on the immune responses being studied.

RNA Sequencing of human THP-1 derived macrophages transcriptomes

Project description:THP-1 cells were treated with phorbol 12-myristate 13-acetate (PMA) at 25μg/ml for 48h.Then remove PMA and rest for 24h to obtain M0 macropahges. Further applied LPS and IFNγ or IL-4 and IL-13 for 24h to obtain M1, M2 macrophages, respectively. During polarization, cells were growth within control medium(LN) or medium with extra lipid mixture(LH).M0,M1,M2 cells were collected and applied to RNA-sequencing. We found that differential activation of macrophage had distinct metabolic signature.Extra lipids supplement did not significantly alter transcriptomes of macrophages.

MitomiR profiling of mitochondria extracted from monocytic cell line

Project description:MiRNAs play pivotal roles in regulating macrophage functions, including differentiation, polarization, recruitment, and activation of inflammation. in this review, to provide novel insight into macrophage differentiation-specific mitomiR signatures and associated mitochondrial pathways, we performed a global miRNA profiling on extracted mitochondria and total cell content of human macrophages. The THP-1 monocytic cell line was treated with phorbol-12-myristate-13-acetate (PMA) to induce differentiation into macrophages The human monocytic cell line THP-1 cells were differentiated into THP-1 derived macrophages with 40 ng/mL phorbol 12-myristate 13-acetate (PMA),The mitochondrial fraction of the cells were enriched and purified using anti-TOM22 microbeads (Miltenyi Biotec). After total RNA extraction, and using Taqman low-density arrays (TLDA), we performed the global miRNA profiling on extracted mitochondria and compared with total cell content

Transcriptome-wide regulation of pre-mRNA splicing and expression by the RNA-binding protein Quaking during monocyte to macrophage differentiation [Microarray]

Project description:Expression levels of the RNA-binding protein Quaking (QKI) are low in monocytes of early, human atherosclerotic lesions, but abundant in macrophages of advanced plaques. Specific depletion of QKI protein impaired monocyte adhesion, migration, differentiation into macrophages, and foam cell formation in vitro and in vivo. RNA-seq and microarray analysis of human monocyte and macrophage transcriptomes, including those of a unique QKI haploinsufficient patient, revealed striking changes in QKI-dependent mRNA levels and splicing of RNA transcripts. Microarray analysis of gene expression and splicing in THP-1 cells transfected with shRNAs, with or without PMA treatment to induce differentiation. 12 total samples were analyzed: THP-1 monocytic cell line transfected with QKI or control shRNAs; samples taken at day 0 or day 3 of PMA-induced differentiation into macrophages.
