Expression analysis to identify inducible genes in T cells

ABSTRACT: Expression microarrays were employed to identify genes induced by phorbol ester and ionomycin stimulation of EL4 cells. EL4 is a murine T cell line. To identify induced genes that were independent of new protein synthesis cells were pre-treated with cycloheximide. This expression study was used in conjunction with histone acetylation ChIP-chip to determine if inducible genes had a specific histone acetylation profile and whether the acetylation profile differed for genes with different kinetics of induction. Keywords: drug treatment comparison Cells were pre-treated with either DMSO or cylcoheximide in DMSO, then they were stimulated with PMA and Ionomycin for either 0h or 4h. 3 biological replicates were used for each treatment-stimulation combination.

Defining the chromatin signature of inducible genes in T cells.

Genome biology 20091006 10

<h4>Background</h4>Specific chromatin characteristics, especially the modification status of the core histone proteins, are associated with active and inactive genes. There is growing evidence that genes that respond to environmental or developmental signals may possess distinct chromatin marks. Using a T cell model and both genome-wide and gene-focused approaches, we examined the chromatin characteristics of genes that respond to T cell activation.<h4>Results</h4>To facilitate comparison of gen ...[more]

Identification of c-Rel and RelA binding regions in stimulated EL4 cells

Project description:c-Rel and RelA are members of the NF-kappaB family of transcription factors. They both have important roles in T cell activation. To discover where in the genome c-Rel and RelA bind and hence which genes they may directly target, we used ChIP-chip with EL4 cells stimulated with phorbol ester (PMA) and Ionomycin. We have identified regions in EL4 cells (background strain: C57BL/6N) activated for 2h or 8h by PMA and Ionomycin, that bind the transcription factors c-Rel and RelA. Immunoprecipitated samples from EL4 cells stimulated with PMA and ionomycin for 2 h and 8 h with antibodies against RelA or c-Rel respectively were used for ChIP-on-chip experiments. In addition, samples from total input and mock immunoprecipitation were used as controls. Biological triplicates were used.

miR-155 role in osteoclast differentiation

Project description:We used microarrays to understand the effect miR-155 has on osteoclast differentiation. RAW264.7 cells were grown in a-MEM supplemented with 10% FBS and antibiotics. mRNA extracted from wild-type RAW264.7 cells and miR-155 mis-expressing cells either before or after 72 hr of stimulation with 20ng/ml RANKL and M-CSF to induce osteoclast differentiation.

MHC Class I Peptides Convey Intracellular mTOR Signals to the Cell Surface

Project description:EL4 cells were treated or not with 20nM rapamycin for 48h. Total RNA was extracted from rapamycin-treated and untreated EL4 cells with TRIzol RNA reagent (Invitrogen) as instructed by the manufacturer. Samples were purified using DNase (Qiagen, Mississauga, ON, Canada) and the RNeasy Mini kit (Qiagen), and the overall quality was analyzed with the 2100 Bioanalyzer (Agilent Technologies). Purified RNA (10 ?g/sample) was hybridized on MM8 385K NimbleGen chips according to the manufacturer's instruction. Arrays were scanned using a GenePix4000B scanner (Axon Instruments, Molecular Devices, Sunnyvale, CA) at 5 ?m resolution. Data were extracted and normalized using the NimbleScan 2.4 extraction software (NimbleGen Systems, Madison, WI). Further microarray analyses were performed using GeneSpring GX 7.3.1.

LEOPARD Syndrome iPS, BJ iPS and Fibroblasts

Project description:Expression data from LEOPARD Syndrome-iPS clones, BJ-iPS cells and parental Fibroblasts 9 samples in total are analyzed. Among 22011 genes in expression data, there are 3657 genes with at least 2 fold expression change between the average of the three fibroblast lines versus all of the iPS lines/HES samples. A heatmap can be generated for the expression levels for the 3657 genes and 9 samples.

Microarray of four types of mouse immune samples including those of the spleen (SP), bone marrow (BM), lymph node (LN), and peripheral blood mononuclear cell (PBMC) and three tumor tissues including MC38, EL4 and LLC

Project description:We performed MIcroarray experiments on a total of 12 immune organs, including spleen (SP), bone marrow (BM), lymph node (LN) and Peripheral blood mononuclear cell (PBMC) and three tumor tissues including MC38, EL4 and LLC. 12 mice from four immune organs, including the spleen (SP), bone marrow (BM), lymph nodes (LN), and Peripheral blood mononuclear cell (PBMC), were isolated using routine experimental methods.9 mice were randomly divided into 3 groups and implanted subcutaneously(s.c.) with EL4 (2.0*10^5 /mice), MC-38 (1.0*10^6 /mice), and LLC-JSP-t2 (2.0*10^5 /mice) cells, respectively. All mice were sacrificed and tumor tissues were collected when the tumor volume reached 100 mm 3 . The tissues were ground up with liquid nitrogen and the lysates were stocked using Trizol for subsequent array analysis. RNA isolation and hybridization were performed by Capitalbio Technology Corporation according to the standard Affymetrix protocol .

Expression data from cord blood derived CD4+ CD25+ (Treg) and CD4+ CD25- (Thelper) cells, both while resting & after stimulation

Project description:Here we compare the effects of stimulation on cord blood derived CD4+ CD25+ (Treg) and CD4+ CD25- (Thelper) cells, isolated by MACS protocols & expanded in vitro using dynabeads. Expansion was carried out at a ratio of 3 beads/cell in the presence of 1000units/ml of recombinant human IL2 for 8 days, followed by 3 days of culture without beads. RNA was extracted from resting cells on day 4 after expansion. Stimulated cells were treated with Ionomycin for 2hrs prior to RNA extraction. Four way comparison of resting and stimulated Tregs versus Thelpers. A total of 18 arrays were analysed containing RNA from 5 individual cord blood donors.

Listeria monocytogenes induces T cell receptor unresponsiveness via its pore-forming toxin listeriolysin O

Project description:The success of many pathogens relies on their ability to circumvent the innate and adaptive immune defenses. How bacterial pathogens subvert host responses is not clear. Cholesterol-dependent cytolysins (CDCs) represent an expansive family of homologous pore-forming toxins produced by more than 20 Gram-positive bacterial species. Here we show that listeriolysin O (LLO), a prototype CDC produced by Listeria monocytogenes, inhibits antigen receptor-induced T cell proliferation. In vivo proliferation of OT II T cells was highly diminished in the presence of wild type but not the LLO-deficient bacteria. T cells pre-exposed to LLO ex vivo were also impaired in proliferation upon TCR activation in vivo and in vitro. Our results suggest that LLO-induced T cell unresponsiveness is due to the sub-threshold activation of T cells via the induction of a calcium-NFAT dependent transcriptional program that drives the expression of negative regulators of TCR signaling. Keywords: Listerilysin O, Ionomycin, 3 hours stimulation Pooled primary CD4+ T cells isolated from spleen and mesenteric lymph nodes were incubated in either control (Ctrl) medium or medium containing 0.25 ug/ml listeriolysin O (LLO) or 1 uM Ionomycin (Iono) for 3 hours. Thereafter, cells were washed and RNA was prepared.
