Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In order to study the gene expression profile in C57Bl/10 mouse blood, we exposed three different groups of animals. First was exposed to PO2 21% or normoxia. The second was exposed to chronic hypoxia (from PO2 21% to PO2 8%) and the third was also exposed to the same chronic hypoxia (CH) protocol but followed by two weeks under normoxia, and called as recovery group. The blood was extracted from inferior vena cava, the RNA was extracted, amplified and hybridized to Affimetrix MOE 430 V2.o chip. The results were analyzed using Partek Genome suite software. Using two fold cuttoff and 0% FDR parameters, we observed genes 512 diferentially expressed, of which one gene was up-regulated in both hypoxic and recovery condition, 202 were up-regulated during CH and then down-regulated after the recovery, 18 genes were down-regulated afteh CH and the up-regulated after recovery, ans finally 9 genes were down-regulated in both CH and recovery conditions.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Severe loss-of-function alleles of DCL1 are embryonic lethal. Defects in cell division were seen as early as the globular stage in the strong loss-of-function allele dcl1-15. Phenotypic work with dcl1-15 and the null allele dcl1-5 suggested that, in addition to the severe patterning defects, the mutants were maturing earlier than wild-type embryos.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Temporal coordination of developmental programs is necessary for normal ontogeny, but the mechanism by which this is accomplished is poorly understood. We have previously shown that two components of the Mediator CDK8 module, CENTER CITY (CCT/MED12) and GRAND CENTRAL (GCT/MED13), are required for timing of pattern formation during embryogenesis in Arabidopsis.
Publication Title
The Arabidopsis Mediator CDK8 module genes CCT (MED12) and GCT (MED13) are global regulators of developmental phase transitions.

Description
The aim of this study is to identify the SPIN1 target genes in liposarcoma cells Overall design: Liposarcoma is one of the most common histological subtypes of soft tissue sarcoma and causes high incidence of morbidity and mortality. Since therapeutic options for liposarcoma treatment are insufficient, there is an urgent need to identify novel therapeutic targets. Here, we show that knockdown of SPIN1, a reader of H3K4me3 and H3R8me2a chromatin marks, strongly reduces proliferation and survival of liposarcoma cells in vitro and in xenograft mouse models. Combining genome-wide chromatin binding and transcriptome analyses, we found that SPIN1 in cooperation with the transcription factor MAZ directly enhances expression of GDNF, an activator of the RET signaling pathway. Accordingly, knockdown of SPIN1 results in reduced levels of GDNF and activated RET explaining diminished liposarcoma cell proliferation and survival. In line with these observations, levels of SPIN1, GDNF, and activated RET are highly increased in human liposarcoma compared to lipoma or normal adipose tissue. Importantly, SPIN1-mediated transcriptional control depends on binding to H3K4me3 suggesting that targeting of this interaction with small molecule inhibitors is a novel strategy to treat liposarcoma.

Description
Pancreas organogenesis is a highly dynamic process where neighbouring tissue interactions lead to dynamic changes in gene regulatory networks that orchestrates endocrine, exocrine and ductal lineage formation. To understand the spatio-temporal regulatory logic we have used the Forkhead transcription factor Foxa2-Venus fusion (FVF) knock-in reporter mouse to separate the FVF+ pancreatic epithelium from the FVF- surrounding mesenchyme and blood vessels to perform a whole genome-wide mRNA expression profiling at embryonic day (E)12.5-15.5. This allowed us to annotate genes and molecular processes differentially regulated in these cell types and compartments of the pancreas to generate a dynamic transcriptional landscape.

Description
This experiment aims to identify the biological pathways and diseases associated with the cytokine Interleukin 13 (IL-13) using gene expression measured in peripheral blood mononuclear cells (PBMCs). Overall design: The experiment comprised of samples obtained from 3 healthy donors. The expression profiles of in vitro IL-13 stimulation were generated using RNA-seq technology for 3 PBMC samples at 24 hours. The transcriptional profiles of PBMCs without IL-13 stimulation were also generated to be used as controls. An IL-13R-alpha antagonist (Redpath et al. Biochemical Journal, 2013) was introduced into IL-13 stimulated PBMCs and the gene expression levels after 24h were profiled to examine the neutralization of IL-13 signaling by the antagonist.
