Caco-2 cocultured with THP-1, time course

Project description:Previously, we constructed a coculture model to analyze the effect of macrophages on intestinal epithelial cells, and found that TNF-a secreted from human macrophage-like THP-1 cells induced cell damage to intestinal epithelial Caco-2 cells (Exp.Cell.Res. 2006, 312(19):3909-19). In this study, we present activation of NF-kB in Caco-2 cells within 15 min after coculturing. To reveal how TNF-a secreted from THP-1 cells affects Caco-2 cells in an early stage of coculture, we exhaustively analyzed the changes of gene expression in Caco-2 cells cocultured with THP-1 cells over the time periods of 0, 1, 3, 6, 24, and 48 h by using a DNA microarray. Differentially expressed genes extracted with maSigPro demonstrated that IEX-1 was the lowest p-value gene, that is, the most significantly changed gene among the up-regulated genes. The genes expressed in a similar pattern to IEX-1 involved immunity, apoptosis, and protein kinase cascade. These findings suggest that the stimuli of TNF-a from THP-1 cells activates NF-kB, leading induction of various gene expression. This pattern of gene expression indicates that not only early defense response but also cell death occurs at the same time, causing inflammatory condition. Caco-2 cells were cultured for 14 days on a semi-permeable support, and THP-1 cells were differentiated with phorbol myristate acetate (PMA) for 4 days in 12-well plates. Then, the semi-permeable support membrane in which Caco-2 cells had been cultured was placed on the 12-well plates on which THP-1 has been cultured.

RNA-seq analysis of the effect of BSA and NaOH added to standard culturing medium on THP-1 macrophages

Project description:The data is supplementary to the RNA-seq analysis of LPS and palmitate stimulation of THP-1 macrophages (E-MTAB-6064), where palmitate for the cell treatment was dissolved in sodium hydroxide and coupled with BSA at a molar ratio 7.5:1. Here we stimulated THP-1 macrophages with the corresponding concentration of BSA (4%) and NaOH (0.4 mM) in the presence of 10 nM phorbol 12-myristate 13-acetate (PMA) for 24 hours added to the standard RPMI 1640 medium with 10% fetal bovine serum (FBS) to estimate the effects and compared them with unstimulated THP-1 macrophages cultured in RPMI 1640 medium with 10% FBS and 10nM PMA.

Transcriptomics of THP-1 macrophages treated with or without IL-26 for 24h

Project description:Purpose: The aim of this study was to obtain a comprehensive transcriptomic analysis of IL-26-exposed macrophages. Methods: THP-1 derived macrophage were generated by incubating THP-1 cells with PMA (50 ng/ml) for 24h.Then THP-1 macrophages were treated with IL-26 for 24h, which were collected and applied to RNA-sequencing. The constructed sequencing library was sequenced using an Illumina Novaseq 6000 system. The expression of transcripts was calculated as fragments per kilobase of exon model per million mapped reads (FPKM). Results: In total, we identified 1303 differentially expressed protein-coding genes between untreated and IL-26-treated macrophages, including 667 up-regulated and 636 down-regulated genes.

The association and difference of normal THP-1 cell and H37Rv infected THP-1 cell.

Project description:①Background:Tuberculosis is mainly a respiratory tract infection caused by mycobacterium tuberculosis and one of the leading causes of death worldwide. According to the Global Tuberculosis Report in 2021, About a quarter of the world's population is infected with Mycobacterium tuberculosis and China is the second highest burden of TB. Although TB diagnosis and prevention techniques have become more mature, the number of TB cases is still increasing, mainly due to: the prevalence of drug-resistant tuberculosis bacteria, tuberculosis and HIV co-infection, long incubation time of mycobacterium tuberculosis difficult to early diagnosis and so on. Therefore, it is of great significance to study the pathogenesis of mycobacterium tuberculosis infection.②Method: THP-1 cells were treated with 50ng/ml PMA for 24 hours, so that THP-1 cell can be induced into macrophages. After that THP-1 macrophages were infected with mycobacterium tuberculosis H37Rv(MOI=1), which were collected and applied to RNA-sequencing. The constructed sequencing library was sequenced using an Illumina Novaseq 6000 system.

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.

Differential gene expression in human THP-1 cell line undifferentiated, 3 days or 8 days differentiated with phorbol myristate acetate (PMA)

Project description:We analysed the capacity of THP-1 cells (differentiated to macrophagoid cells) to recognize RNA sequences via pattern recognition receptors in vitro. Gene expression was analysed by RNA-Microarray. Cytokine production was analysed by ELISA assays. We used microarrays to investigate differential gene expression in THP-1 cell line undifferentiated in comparison with 3 days or 8 days differentiated with phorbol myristate acetate (PMA). Microarray analysis revealed differential gene expression patterns of THP-1 when differentiated. THP-1 cells, undifferentiated, 3 days PMA-differentiated and 8 days PMA-differentiated
