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

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

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.

Transcription profiling by array of human jurkat cells after mitogen stimulation

Project description:Gene expression analysis identified 27 of these 744 p300 and pol II associated genes as significantly increased (p? 0.05) within the first hour following mitogen stimulation Experiment Overall Design: Total RNA was purified from Jurkat T-cells treated 0, 30, and 60 min with phorbol ester and ionomycin. Antisense biotin-labeled RNA (aRNA) suitable for application to the Affymetrix microarray platform was generated using the Ambion MessageAmp 2-Biotin Enhanced kit as suggested by the manufacturer (www.Ambion.com). Purified biotin-labeled aRNA was fragmented and hybridized to U133 plus 2 GenechipsTM (Affymetrix), as recommended by the manufacturer. All samples were hybridized as technical replicates. Affymetrix U133 plus 2 GenechipsTM contain probe-sets corresponding to over 56,000 targets.

Human memory T cells of the bone marrow are resting and maintain long-lasting memory

Project description:To compare human memory CD4+ T cell subsets in peripheral blood (PB) and bone marrow (BM) of healthy individuals at transcriptional level, we analyzed the global gene expression of ex vivo PB CD69- as well as BM CD69- and CD69+ memory CD4+ T cells from 4 paired PB and BM samples. The gene expression of these subsets was additionally compared to the transcriptional profile of 8 PB samples taken ex vivo or stimulated with phorbol myristate acetate (PMA) and Ionomycin for 3 hours.

Effects of PMA on exon usage of HL60, THP-1, and U937 cells

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.

Greater transiency in modulation of gene expression is the predominant difference between the actions of bryostatin 1 and phorbol ester in LNCaP and U937 cells [set 2]

Project description:Bryostatin 1, like the phorbol ester PMA, activates protein kinase C (PKC) in vitro but paradoxically blocks many phorbol ester responses in vivo. Results with a limited panel of genes suggested that transiency of action was an important mechanism contributing to this differential cellular response. Here, we examined global gene expression in LNCaP and U937 cell lines to probe the extent to which transiency of action captures the difference in response. While different genes showed different patterns of relative response, the overall pattern was reflective of an initial PMA-like response to bryostatin 1 followed by variable transiency of the continued response. This conclusion was further strengthened by detailed time course measurements by qPCR of selected genes. Merle 23, a bryostatin derivative with biological behavior intermediate between that of bryostatin 1 and PMA, was likewise intermediate for transiency of action. Both the LNCaP and U937 cell lines behaved similarly, but the extent of transiency in response to bryostatin 1 was greater in the LNCaP cells.
