Comparative transcriptome analysis of Th22 and Th17 cells

Project description:Microarray was used to delineate the global gene expression profile underlying the specific developmental program of two divergent antigen-specific T helper subsets (Th22 versus Th17) by identifying upregulation or downregulation of key lineage-determining transcription factors, cytokines, chemokines and other genes that govern their functional attributes. To identify factors that might distinguish the Th22 and Th17 developmental programs, comparative global transcriptome analysis between these 2 subsets was performed. Naïve splenic CD4+ T cells from OT-II-transgenic mice were isolated and grown in vitro under T-helper lineage-specific conditions in the presence of cognate antigen (ovalbumin) to identify their distinctive global gene-regulation profiles.

Induction of pathogenic Th17 cells by salt inducible kinase SGK-1 (NaCl)

Project description:Th17 cells are highly proinflammatory cells that are critical for clearing extracellular pathogens like fungal infections and for induction of multiple autoimmune diseases1. IL-23 plays a critical role in stabilizing and endowing Th17 cells with pathogenic effector functions2. Previous studies have shown that IL-23 signaling reinforces the Th17 phenotype by increasing expression of IL-23 receptor (IL-23R)3. However, the precise molecular mechanism by which IL-23 sustains the Th17 response and induces pathogenic effector functions has not been elucidated. Here, we used unbiased transcriptional profiling of developing Th17 cells to construct a model of their signaling network and identify major nodes that regulate Th17 development. We identified serum glucocorticoid kinase-1 (SGK1), as an essential node downstream of IL-23 signaling, critical for regulating IL-23R expression and for stabilizing the Th17 cell phenotype by deactivation of Foxo1, a direct repressor of IL-23R expression. A serine-threonine kinase homologous to AKT4, SGK1 has been associated with cell cycle and apoptosis, and has been shown to govern Na+ transport and homeostasis5, 6 7, 8. We here show that a modest increase in salt (NaCl) concentration induces SGK1 expression, promotes IL-23R expression and enhances Th17 cell differentiation in vitro and in vivo, ultimately accelerating the development of autoimmunity. The loss of SGK1 resulted in abrogation of Na+-mediated Th17 differentiation in an IL-23-dependent manner. These data indicate that SGK1 is a critical regulator for the induction of pathogenic Th17 cells and provides a molecular insight by which an environmental factor such as a high salt diet could trigger Th17 development and promote tissue inflammation.

Transcription profiling of mouse spleen CD4+ CD44Low CD62LHigh cells stimulated with anti-CD3 or anti-CD28 in the presence or absence of hTGFb-1 and mouse IL-6

Project description:Mouse spleen CD4+CD44LowCD62LHigh cells were stimulated with 2ug/ml anti-CD3(eBioscience), 2ug/ml anti-CD28 (eBioscience) in the presence (Th17 condition) or absence (Th0 condition) of hTGFb-1 (1ng/ml eBioscience), mouse IL-6(10ng/ml eBioscience). Cells were collected after 24 hourÕs culture using RNAeasy columns (Qiagen) for total RNA isolation. Isolated total RNA from Th0 and Th17 conditioned cells were submitted for the microarray gene transcription comparison analysis using Affymetrix Mouse 430A 2.0 array chips.

Genome wide STAT3 RNAi expression profiling data from Thp,Th0 and Th17 cells

Project description:STAT3 is an immidiate regulator of Th17 differentiation. STAT3 difieciency downmodulate Th17 specific genes and Th17 responses. Therefore, we intend to identify genome wide targets of STAT3. We used microarrays to profile gene expression of STAT3 regulated genes during Th17 polarization. Total RNA was extracted from non-targeting and STAT3 siRNA treated Thp, Th0 and Th17 cell samples from different time points. Total RNA subjected to poly-A selection and hybridization on Affymetrix microarrays.

miRNA-seq study between Th0 and Th17 cells

Project description:To explore the differences in miRNA profiles, naive CD4+CD62L+ helper T cells were sorted by magnetic cell sorting from spleens of female C57BL/6 mice and were induced to differentiate into Th1 or Th17 cells, then total RNA was extracted and miRNA-seq were conducted. The results showed that many microTNAs presented a different expression pattern between Th1 and Th17 cells, which prompted us to further study their roles in Th117 differenciation. miRNA profiles of Th0 and Th17 cells were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500

Expression data from MDA-MB-231 parental and xenograft tumor cells treated with Smac mimetic SM-164.

Project description:Small-molecule Smac mimetics target inhibitor of apoptosis (IAP) proteins to induce TNFÎ±-dependent apoptosis in cancer cells and several Smac mimetics have been advanced into clinical development as a new class of anticancer drugs. However, preclinical studies have shown that only a small subset of cancer cell lines are sensitive to Smac mimetics used as single agents and these cell lines are at risk of developing drug resistance to Smac mimetics. Thus, it is important to understand the molecular mechanisms underlying intrinsic and acquired resistance of cancer cells to Smac mimetics in order to develop effective therapeutic strategies to overcome or prevent Smac mimetic resistance. We established Smac mimetic resistant sublines derived from MDA-MB-231 breast cancer cells, which exhibit exquisite sensitivity to the Smac mimetic SM-164, and used microarrays to detail the global programme of gene expression underlying SM-164 resistance in MDA-MB-231 cells and identified differentially expressed genes in SM-164-resistant and -sensitive MDA-MB-231 cells. SCID mice with MDA-MB-231 xenograft tumors were treated with 5 mg/kg of SM-164 intravenously for 5 days/week for 2 weeks. SM-164-regressed MDA-MB-231 tumors regrew after treatment ended. Tumor cells from these regrown MDA-MB-231 tumors were isolated and total RNAs were prepared for microarray analysis.

A validated regulatory network for Th17 cell specification

Project description:Th17 cells have critical roles in mucosal defense and are major contributors to inflammatory disease. Their differentiation requires the nuclear hormone receptor RORγt working with multiple other essential transcription factors (TFs). We have used an iterative systems approach, combining genome-wide TF occupancy, expression profiling of TF mutants, and expression time series to delineate the Th17 global transcriptional regulatory network. We find that cooperatively-bound BATF and IRF4 contribute to initial chromatin accessibility, and with STAT3 initiate a transcriptional program that is then globally tuned by the lineage-specifying TF RORγt, which plays a focal deterministic role at key loci. Integration of multiple datasets allowed inference of an accurate predictive model that we computationally and experimentally validated, identifying multiple new Th17 regulators, including Fosl2, a key determinant of cellular plasticity. This interconnected network can be used to investigate new therapeutic approaches to manipulate Th17 functions in the setting of inflammatory disease. 143 RNA-seq, 83 ChIP-seq, 65 ChIP-seq controls, and 16 FAIRE-seq
