Project description:Analysis of the transcriptome of THP-1 cells upon Huh7 cell-derived ectosomes incubation. Monocytic THP-1 cells were incubated with or without ectosomes (10 mg/ml) derived from scramble sequence transfection (Scramble Ecto) or PKM2 knocking down (PKM2 KD Ecto) Huh7 cells for 24 h. Results provide a novel insight into monocyte differentiation.
Project description:Open chromatin regions have been shown to associate with the location of transcriptiotal enhancers, i.e., the binding locations of DNA-binding transcription factors. To investigate the effects of short-term treatment by the nuclear hormone 1α,25-dihydroxyvitamin D3 (VD), a specific ligand of the transcription factor vitamin D receptor, on chromatin accessibility, FAIRE-seq was utilized on the chromatin samples from THP-1 monocytic leukemia cells that were treated with 100 nM 1α,25-dihydroxyvitamin D3 for 20, 40, 60, 80, 100 and 120 min, or with vehicle (0.1% (v/v) ethanol) for 20 and 100 min. THP-1 monocytic leukemia cells were treated with 100 nM 1α,25-dihydroxyvitamin D3 for 20, 40, 60, 80, 100 and 120 min or with vehicle (0.1% (v/v) ethanol) for 20 and 100 min. Chromatin sample from one biological replicate for each time point was subjected to the FAIRE-seq protocol and subsequent data analysis using an Input chromatin sample as control.
Project description:Monocytic leukemia cell line, THP-1 cells are known to respond to CXCL14. To identfy transcriptional regulation of CXCL14 signalling, we analyse gene expression changed with CXCL14 treatment. THP-1 treated with CXCL14 or PBS treated sample were used.
Project description:Analysis of acute effects of ligand-treatment on vitamin D receptor binding genome-wide using ChIP-seq. THP-1 monocytic leucemia cells were treated with 1?,25(OH)2D3 (1,25D) or left unstimulated to investigate the acute effects of VDR chromatin occupancy. We identified in total 2340 VDR binding sites with and without the ligand. Without the ligand, there is a considerable presence of VDR already on the chromatin. However, upon a short (40 min) ligand treatment VDR shifts from sites that rarely contain a DR3 type element to sites that frequently contain one or more DR3-type element. Genome-wide identification of VDR binding in THP-1 cells at the unstimulated state and after 40 min ligand (10 nM 1?,25(OH)2D3 (1,25D, calcitriol)) treatment.
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
Project description:Transcriptome comparison to assess the responses of human monocytic cells (THP-1) to gold-nanoparticles (Au-NPs) of two different diameter sizes (5 or 20 nm) with different surface functional groups, i.e., alkylammonium bromide, alkyl sodium carboxylate, or poly(ethylene glycol) (PEG)-terminated thiolate Au-NPs.
Project description:To explore the mechanism related to the induction of monocytic differentiation in AML combination of ATRA and RAD001, gene expression patterns of THP-1 cells were analyzed using the Agilent Whole Human Genome Expression Array. Gene expression patterns of THP-1 cell cultured under four different conditions were analyzed. The conditions were as follows; 1, untreated. 2, treated with ATRA (1mM) and RAD001 (2.5nM). Total RNA was extracted at 5 days after starting treatment.
Project description:Streptococcus suis is an important zoonosis pathogen that causes significant economic losses worldwide characterized by meningitis, septicaemia, arthritis, bronchopneumonia endocarditis. Streptcoccus suis 2 strain SC19 was isolated in Sichuan province in China, during the outbreak in 2005. Septicemia is most popular symptoms for SC19 infection, and mortality is high. We used human acute monocytic leukemia cell line (THP-1) infected SC19 to analysis the pathomechanism of septicemia in SS2 infection. Human acute monocytic leukemia cell line (THP-1) cells were stimulated with Streptcoccus suis 2 (SS2) strain SC19. We added SS2 to THP-1 cells at a MOI of 1:1 (bacteria/cells). Uninfected control cells were incubated with PBS only. After 3 hours incubation, cells were collected for RNA extraction and hybridization on Affymetrix microarrays. A total of 4 samples were challenged, and 4 samples were used as controls. 4 microarrays were used in this experiment.
