Project description:Differentially regulated miRNA candidates in H37Rv infected THP-1 cells were analysed with respect to uninfected THP-1 reference samples. THP-1 cells are monocytes differentiated to macrophages after treatment with PMA for 48 hrs. Total RNA was isolated from infected THP-1 cells after 24 hrs of infection, cDNA was synthesized for TLDA real time PCR reaction using TaqMan MicroRNA Reverse Transcription kit and Megaplex Human Pool A and Pool B stem loop RT primers (version 3.0) as per manufacturer’s protocol. Further real time reaction was performed on QuantStudio 12K Flex Real-Time PCR System (Applied Biosystems) by using cDNA (without pre-amplification) on TLDA card A and card B (version 3.0).

Project description:Quercetin is a flavonol modifying numerous cell processes with potent antiproliferative effects on cancer cell-lines. The aim of this study was to explore by gene-array analysis the effect of quercetin on cancer-related gene expression in HepG2 cells, followed by verification with RT-PCR and analysis of the expected phenotypic changes (migration, cell cycle, cell proliferation). Quercetin induces significant changes on cell-adhesion related genes, leading to reduced migratory capacity and disorganization of the actin cytoskeleton. Several genes related to DNA functions, cellular metabolism and signal-transducer activities were also modified, while an early effect on G–protein related cascades possibly via protease-activated receptor 2 and phospholipase C-?1 was identified. Cyclin-D associated events in G1 and ubiquitin-dependent degradation of cyclin-D1 were also affected, resulting in cell-cycle arrest without activation of apoptosis pathways. In conclusion quercetin (3?M) exerts its cellular effects by modifying numerous genes related to mechanisms involved in cancer initiation and promotion. HepG2 cells were serum starved for 24 hours and were then treated with serum free medium with or without quercetin (3?M). Total RNA was collected at 2, 4, 12 and 24 hours and was used for gene-array experiments.

Project description:There is currently no human macrophage cell line and in vitro experiments requiring these cells currently require mitogenic stimulation of a macrophage precursor cell line (for example THP-1 cells) or ex vivo maturation of circulating primary monocytes. We have derived a unique sub-clone of the THP-1 cell line capable of spontaneous and perpetual differentiation into alveolar macrophage-like cells. Here we used the Agilent G4851C (v3) array to look at the gene expression of the new cell line which can be compared it with THP-1 cells and PMA stimulate THP-1 cells (Accession number E-MTAB-4153). In addition the new human alveolar macrophage like cell line has been treated with unmodified lipid to look at lipid uptake by these cells and the effect on gene expression.

Project description:Myeloid leukemia cell lines HL60, THP-1, and U937 undergo macrophage-like differentiation after treatment with phorbol ester. To explore genes whose exon usage was altered during macrophage differentiation, we compared exome of PMA-treated (differentated) and vehicle-treated (undifferentiated) myeloid cell lines. HL60, THP-1, and U937 cells were treated with either phorbol 12-myristate 13-acetate (PMA,30nM) or its vehicle (DMSO) for 3 days, and subjected to exome analysis using Affymetrix human exon 1.0ST arrays.

Project description:THP-1 monocyte-like suspension cells can be differentiated into macrophage-like adherent cells by TPA (PMA) treatment. Proteomic analysis was carried out on (i) normal THP-1 cells, (ii) THP-1 cells in which KPNA1 (importin-alpha5) was knocked down or not by siRNA, and (iii) THP-1 TetOn-KPNA2 (importin-alpha1) cells induced or not by Dox. Total and nuclear proteins were prepared from both the monocyte-like and macrophage-like cells and quantified by a label-free method.

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.

Project description:The aim was to investigate mechanisms contributing to quercetin’s previously described effects on cell-proliferation and -differentiation, which contradicted its proposed anti-carcinogenic potency. In a 10-day experiment, 40 µM quercetin stabilized by 1mM ascorbate reduced Caco-2 differentiation up to 50% (P<0.001). Caco-2 RNA from days 5 and 10, hybridized on HG-U133A2.0 Affymetrix® GeneChips®, showed 1,743 affected genes on both days (P<0.01). All 14 Caco-2 differentiation-associated genes showed decreased expression (P<0.01), including intestinal alkaline phosphatase that was confirmed technically (qRT-PCR) and functionally (enzyme-activity). The 1,743 genes contributed to 27 affected pathways (P<0.05) categorized under 6 gene ontology (GO) processes, including apoptosis and cell-cycle. Genes within these GO-processes showed fold changes that suggest increased cell-survival and -proliferation. Furthermore, quercetin downregulated expression of genes involved in tumor-suppression and phase II metabolism, and upregulated oncogenes. Gene expression changes mediated by ascorbate-stabilized quercetin were concordant with those occurring in human colorectal carcinogenesis (≈ 80-90%), but were opposite to those previously described for Caco-2 cells exposed to quercetin in the absence of ascorbate (≈ 75-90%). In conclusion, gene expression among Caco-2 cells exposed to ascorbate-stabilized quercetin showed mechanisms contrary to what is expected for a cancer-preventive agent. Whether this unexpected in vitro effect is relevant in vivo, remains to be elucidated. Keywords: Colon cancer; Caco-2; quercetin; differentiation

Project description:Lipid laden macrophages (LLM) can often be found in the airway and may indicate aspiration secondary to gastro-oesophageal reflux (GOR). GOR is often associated chronic inflammatory airways diseases. We therefore sought to determine whether lipid droplets from undigested or partially digested food had an effect on macrophage gene expression leading to bronchial inflammation. To test this, we generated an in vitro model using differentiated THP-1 cells which were treated with a high fat liquid feed. Gene expression, using the Agilent G4851C (v3) array, in phorbol myristate acetate (PMA) differentiated THP-1 cells was compared to undifferentiated cells and lipid treated differentiated THP-1 cells.
