Expression profiling comparisons of human CD4+ T cells treated with RORgt inhibitors

ABSTRACT: The aim of this study was to identify differential gene expression resulting from the inhibition of RORgt in human CD4+ T cells. Human CD4+ T cells were cultured with anti-CD3/anti-CD28 mAb for 20 to 60 hours concurrent with exposure to Vehicle (DMSO), TMP778 (0.2 uM) or TMP776 (0.2 uM). All samples were then processed for RNA extraction, labeling, and hybridization to Affymetrix arrays.

IL-17-producing CD4(+)Th17 cells, CD8(+)Tc17 cells, and γδ T cells play critical roles in the pathogenesis of autoimmune psoriasis. RORγt is required for the differentiation of Th17 cells and expression of IL-17. In this article, we describe a novel, potent, and selective RORγt inverse agonist (TMP778), and its inactive diastereomer (TMP776). This chemistry, for the first time to our knowledge, provides a unique and powerful set of tools to probe RORγt-dependent functions. TMP778, but not TMP776 ...[more]

Expression profiling comparisons of human PBMC treated with class I/IIb or class IIa HDAC inhibitors

Project description:The aim of this study was to identify differential gene expression resulting from the inhibition of class IIa HDACs in human PBMC. Human PBMC were cultured ex vivo with a mitogenic stimulus (1 ug/ml phytohemagglutinin, PHA) for 60 hours concurrent with exposure to vehicle (DMSO), vorinostat (3 uM), or TMP195 (3 uM). In addition to the whole PBMC populations, a portion of the cultures treated with DMSO or TMP195 were used for FACS purification of mutually exclusive CD3+ (T cell), CD19+ (B cell), and CD14+ (monocyte) populations. All samples were then processed for RNA extraction, labeling, and hybridization to Affymetrix arrays. Vehicle vs. vorinostat vs. TMP195 treatments in PBMC; Vehicle vs. TMP195 treatment in CD3+, CD19+ or CD14+ cells

Expression profiling of lung T cell subsets from wild-type and Serpinb1a-/- mice

Project description:The aim of this study was to identify differential gene expression in lung T cell subsets upon germline Serpinb1a ablation. CD8-CD19- lymphocytes enriched by negative selection from digested lungs of naÃ¯ve, 9-12 week old wild-type 129S6 mice or Serpinb1a homozygous null mice were FACS sorted into CD4+ CCR6+ effector/ memory T cells, gd T cells, or CD4+ CD25hiCD127low regulatory T cells. FACS sorted cells were collected into RLT buffer (Qiagen) directly, lysed, and total mRNA was isolated using Quiagen's RNeasy mini kit. Wild-type vs. Serpinb1a-/- gd+ T cells, CD4+ CCR6+ effector/ memory T cells, or CD4+ CD25hiCD127low regulatory T cells

Expression profiling of MDR1+ and MDR1- human memory T cells from the blood and clinically-inflamed gut tissue

Project description:The aim of this study was to characterize the transcriptional signature of MDR1+ human memory T cells isolated from clinically inflamed gut tissue, and compare it to local MDR1- memory T cells Human mononuclear cells were isolated from the peripheral blood of a healthy adult donor (Ficol density centrifugation) or from resected lesioned gut tissue of a patient with active Crohn's disease. For cell isolation from gut tissue, tissue was rinsed with PBS, treated with 0.15% DTT to remove mucous, then with 1 mM EDTA to remove epithelial cells and intra-epithelial lymphocytes. Remaining tissue was digested using Liberase-TL (Roche) plus 10 U/mL DNase I. Mononuclear cells were then filtered through 70 mM nylon filters and isolated via a 30%/ 70% Percol gradient. Mononuclear cells from blood or gut tissue were FACS-sorted into CD3+ CD4+ CD45RO+ MDR1+ or MDR1- memory T cells, using Rhodamine 123 (Rh123) efflux as a surrogate for MDR1 expression/ activity. Sorted cells were harvested directly ex vivo (without further in vitro culture or manipulation) prior to RNA extraction. MDR1- memory CD4+ T cells vs. MDR1+ memory CD4+ T cells from healthy donor peripheral blood or from active Crohn's disease lesioned tissue; MDR1- or MDR1+ memory CD4+ T cells from blood vs. inflamed gut tissue

Transcriptional responses of wild-type and Gcn2-/- Th17 cells to halofuginone and rapamycin

Project description:This study was designed to evaluate similarities and differences between transcriptional responses of developing Th17 cells to the prolyl-tRNA synthetase inhibitor, halofuginone, and the mTOR inhibitor, rapamycin. Further comparisons between wild-type and Gcn2-/- Th17 cells allow for investigation into which gene modules regulated by halofuginone or rapamycin treatment require Gcn2. Murine CD4+ CD25- T cells were magnetically isolated from wild-type or Gcn2-/- T cells. These cells were activated through anti-CD3/ anti-CD28 antibodies and polarized into Th17 cells using TGFb plus IL-6. 10 nM halofuginone, 10 nM rapamycin, or vehicle control (DMSO) were added to cultures at the time of activation. Cells were harvested at 4, 18, or 72 hours post-activation and differentiation. RNA was isolated from each sample and used for microarray analysis. Each culture condition and time-point was repeated twice in independent experiments using cells isolated from different wild-type or Gcn2-/- mice. Vehicle versus halofuginone, vehicle versus rapamycin, halofuginone versus rapamycin. Gcn2-/- versus wild-type T cells treated with vehicle, halofuginone, or rapamycin.

Gene expression profiles of Herceptin-resistant breast cancer cells

Project description:Herceptin (trastuzumab) is a humanized monoclonal antibody targeted to the Her2 receptor tyrosine kinase. Despite a robust response rate to Herceptin-based therapies in Her2-positive patients, resistance frequently arises within one year of the initial response. To address the mechanism of Herceptin resistance, we selected clonal variants of Her2-positive BT474 human breast cancer cells (BT/HerR) that are highly resistant to the anti-proliferative effects of Herceptin in the presence of 0.2 uM or 1.0 uM Herceptin. Our original report on these cell lines demonstrated sustained PI3K/Akt signaling and sensitivity to PI3K inhibitors in BT/HerR cells in the presence of Herceptin, suggesting dysregulation of that pathway as an essential component of Herceptin-resistant proliferation. To address the mechanism by which BT/HerR cells and their PI3K/Akt signaling pathway became resistant to Herceptin, we analyzed gene expression profiles of two clones (BT/HerR1.0C and BT/HerR 1.0E) that were selected in 1.0 uM Herceptin and two clones (BT/HerR0.2D and BT/HerR 0.2J) that were selected in 0.2 uM Herceptin, in comparison to the Herceptin sensitive BT474 parent cells. Total cellular RNAs were extracted from BT474 (control) and four BT/HerR subclones, two that were originally selected in 1.0 uM Herceptin and two that were originally selected in 0.2 uM Herceptin. Two RNA samples independently prepared from each clone were analyzed.
