  1. RGS9-2-controlled adaptations in the striatum determine the onset of action and eficacy of antidepressants in neuropathic pain states ArrayExpress

    ID: E-GEOD-71527

    Description: The striatal protein Regulator of G protein signaling-2 (

  2. Striatal microRNA controls cocaine intake through CREB signalling ArrayExpress

    ID: E-GEOD-21901

    Description: iption factor CREB (cAMP response element-binding protein) is considered a core regulator of cocaine reward. We show that miR-212 controls responsiveness to cocaine by dramatically amplifying striatal CREB signaling. This action occurs through miR-212-enhanced Raf-1 activity, resulting in adenylyl cyclase sensitization and increased expression of the essential CREB co-activator TORC (Transducer of Regulated CREB; also known as CRTC). Our findings suggest that striatal miR-212 signaling plays a key role in vulnerability to addiction, and that noncoding RNAs such as the miRNAs may serve as novel targets for the development of anti-addiction therapeutics. To identify potential targets for miR-212, we transfected cells with a vector to overexpress miR-212 or an empty vector. We then analyzed profiled gene ex...

  3. Transcriptomic responses of Anguilla anguilla elvers fed dietary LPS ArrayExpress

    ID: E-GEOD-53346

    Description: immune status of the animals. Elvers (1.7 ± 0.2 g) obtained from local fishermen (Delta del Ebro, Spain) were fed at different doses of c (0, 20 and 40 μg LPSp kg BW-1 day-1) for a period of 70 days (4 replicates per dietary group). LPSp was added to the diet (52% protein, 24% fat, 9% ash) by top coating the pellets with the lyophilized powder of LPSp dissolved in 2% fish oil (diets manufactured by ALLERQUA, Denmark). The trial was conducted in 100 L tanks (40 L functional volume) connected to a recirculation unit (IRTAmar®) and water quality was as follows: temperature, 21 ± 0.5 ºC; pH, 7.5 ± 0.1; photoperiod, 12 L:12 D and oxygen at saturation levels. At the end of the trial, fish were measured for growth (BW), size dispersion, histological organization of the intestinal mucosa and the transcriptomic responses of the spleen were evaluated by means of a 60K (15000 gene signatures) custom oligonucleotide microarray (Agilent Technologies Inc.). No significant differ...

  4. Identification of Differential Gene Expression During Transition of Bovine Corpus Luteum from Early To Mid–Phase ArrayExpress

    ID: E-GEOD-10662

    Description: of PGF2alpha receptors; therefore differences in signaling events might be responsible for LS. Hence differential gene expression at two developmental stages, days 4 (D-4) and 10 (D-10) post estrus, might account for differences in signal transduction pathways associated with LS. This possibility was examined in these studies. Microarray analysis (n=3 per stage) identified 167 genes that were differentially expressed (p<0.05). These were categorized into genes involved in cell signaling, steroidogenesis and metabolism, protein degrad...

  5. Systems biology of gene expression of bladder papilloma cells modulated by a malignant-derived extracellular matrix ArrayExpress

    ID: E-GEOD-9291

    Description: iles of RT4 cells grown on Matriges over 12 hours-9 days timecourse. Total 5881 hypervariable (HV) genes were found to vary significantly over the time points, indicating a response to matrix change. Correlational clustering showed these HV genes fell into distinct families, predominantly genes which became highly expressed on ECM. Another cluster show genes expressed at 12 hours after grown on Matrigel and...

  6. Global transcriptional response of macrophage-like THP-1 cells ArrayExpress

    ID: E-GEOD-19315

    Description: dual genes. However, it is known that many of the signaling pathways activated by Stxs regulate the expression of multiple genes in mammalian cells. To expand the scope of analysis of gene expression and to better understand the underlying mechanisms for the various effects of Stxs on cell functions, we carried out comparative microarray analyses to characterize the global transcriptional response of human macrophage-like THP-1 cells to Shiga toxin type 1 (Stx1) and LPS. Data were analyzed using a rigorous combinatorial a...

  7. Gene profiling studies in postnatal Mfrprd6 mutant eyes reveal differential expression of Prss56, a trypsin-like serine protease, and genes involved i... ArrayExpress

    ID: E-GEOD-53411

    Description: he expression of RPE-specific visual transduction protein, RPE65, was significantly decreased in Mfrprd6 mutants. As an indirect consequence of the primary RPE cell defect due to the Mfrprd6 mutation, retinal specific transcripts Rgr, Pde6a, GuCa1b, and Rgs9 were also significantly decreased. We also confirmed the significantly elevated levels of Prss56, a gene previously associated with myopia and open angle glaucoma. In the Mfrprd6 mutant, a progressive increase in Prss56 mRNA levels from 14- to 70-fold was observed from P7 to P21, respectively. In situ hybridization and glutamine synthetase staining of mutant eyes indirectly identified Müller glia in the inner nuclear layer of retina as the cell type expressing the Prss56 transcript. This experiment had one model term, a combination of strain and time, which consisted of four levels (B6_P0, B6_P14, Rd6_P0 and Rd6_P14). Three biological replicates were used per term level. A total of 12 Affymetrix Mouse 430v2 Arrays were used in gene expression analysis....

  8. Combined RNA-seq and Polr2a ChIP-seq Identifies Gene Targets for Transcriptional Regulation in Vasopressin-Sensitive Collecting Duct Cells ArrayExpress

    ID: E-GEOD-79573

    Description: duced changes in the abundance of the aquaporin-2 protein. Defects in the long-term regulation have been implicated in multiple water balance disorders. With the objetive to identify genes that are transcriptionally regulated in response to vasopressin in cultured mouse collecting duct cells (mpkCCD), we carried out both RNA-seq to measure all transcripts (n=9) and ChIP-seq for RNA polymerase II (Polr2a) binding along the genome (n=3). Observations were made both after 24-hr treatment wit...

  9. Effects of knockdown of ROCK1 and ZIPK on gene expression in cultured human vascular smooth muscle cells ArrayExpress

    ID: E-GEOD-56819

    Description: o-associated kinase (ROCK) and zipper-interacting protein kinase (ZIPK) have been implicated in diverse physiological functions, including smooth muscle contraction, cell proliferatio...

  10. Runx2 Transcriptome of Prostate Cancer Cells: Insights into Invasiveness and Bone Metastasis ArrayExpress

    ID: E-GEOD-24261

    Description: lators (SDC2, Twinfilin, SH3PXD2A), intracellular signaling molecules (DUSP1, SPHK1, RASD1) and transcription factors (Sox9, SNAI2, SMAD3) functioning in epithelium to mesenchyme transition (EMT), tissue invasion, as well as homing and attachment to bone. Consistent with the gene expression data, induction of Runx2 in C4-2B cells enhanced their invasiveness. It also promoted cellular quiescence by blocking the G1/S phase transition during cell cycle progression. Furthermore, the cell cycle block was reversed as Runx2 levels declined after Dox withdrawal. Conclusions: The effects of Runx2 in C4-2B/Rx2dox cells, as well as similar observations made by employing LNCaP, 22RV1 and PC3 cells, highlight multiple mechanisms by which Runx2 promotes the metastatic phenotype of PCa cells, including tissue invasion, homing to bone and induction of high bone turnover. Runx2 is therefore an attractive target for the development of novel diagnostic, prognostic and therapeutic approaches to PCa management. Targeting Runx2 may prove more effective than focusing on its individual downstream genes and pathways. C4-2B/Rx2dox cells were subjected to microarray gene expression analysis after one and two days of treatment with either Dox or vehicle in biological quadruplicates (a total of 16...
