Sentrix Human-6 Expression BeadChip
Description
Special AT-rich binding protein 1 (SATB1) is a global chromatin organizer and a transcription factor induced by interleukin-4 (IL-4) during the early T helper 2 (Th2) cell differentiation. In this study, we investigated the role of SATB1 in T helper cell differentiation by performing gene expression profiling of human differentiating Th cells in which expression of SATB1 was downregulated by RNA interference (RNAi). Our results indicate that SATB1 is involved in the regulation of more than three hundred genes in primary human CD4+ T cells, including several IL-12 and/or IL-4 regulated factors, suggesting a role in the development or function of Th subtypes.

Description
STAT6 is a major transcription factor driving the polarization of Th2 cells in response to cytokine IL-4. Here we have analyzed on a genome wide level the STAT6 mediated gene expression after IL-4 induction in naive human CD4+ T cells. RNAi mediated STAT6 knockdown was used to reveal the genes specifically regulated by STAT6.

Illumina HiSeq 2500
Description
Human CD4 positive T cells were isolated from cord blood using CD4 positive isolation kit from Dynal. Cells were activated with plate bound anti-CD3 and soluble anti-CD28 in presence (iTreg) or absence (Th0) of IL2, TGF beta and ATRA. The cells were harvested at 0, 0.5, 1, 2, 4, 6, 12, 24, 48, and 72 hours. Overall design: Comparing the gene expression in activated CD4+ cells and iTreg differentiated cells in human. 9 time points, 3 replicates for each time point.

Description
Advanced ovarian cancers are initially responsive to chemotherapy with platinum drugs but develop drug resistance in most cases. We showed recently that hepatocyte growth factor (HGF) enhances death of human ovarian cancer cell lines treated with cisplatin (CDDP) and that this effect is mediated by the p38 mitogen-activated protein kinase. In this work, we integrated genome-wide expression profiling, in silico data survey, and functional assays to identify transcripts regulated in SK-OV-3 ovarian cancer cells made more responsive to CDDP by HGF. Using oligonucleotide microarrays, we found that HGF pretreatment changes the transcriptional response to CDDP. Quantitative reverse transcription-PCR not only validated all the 15 most differentially expressed genes but also confirmed that they were primarily modulated by the combined treatment with HGF and CDDP and reversed by suppressing p38 mitogen-activated protein kinase activity. Among the differentially expressed genes, we focused functional analysis on two regulatory subunits of the protein phosphatase 2A, which were down-modulated by HGF plus CDDP. Decrease of each subunit by RNA interference made ovarian cancer cells more responsive to CDDP, mimicking the effect of HGF. In conclusion, we show that HGF and CDDP modulate transcription in ovarian cancer cells and that this transcriptional response is involved in apoptosis regulation. We also provide the proof-of-concept that the identified genes might be targeted to either increase the efficacy of chemotherapeutics or revert chemotherapy resistance.

Description
The biologic basis for NSCLC metastasis is not well understood. Here we addressed this deficiency by transcriptionally profiling tumors from a genetic mouse model of human lung adenocarcinoma that develops metastatic disease owing to the expression of K-rasG12D and p53R172H. We identified 2,209 genes that were differentially expressed in distant metastases relative to matched lung tumors. Mining of publicly available data bases revealed this expression signature in a subset of NSCLC patients who had a poorer prognosis than those without the signature.
