- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
TGF-b1-stimulation induces an epithelial dedifferentiation-process, throughout which epithelial cell sheets disintegrate and gradually switch into fibroblastic-appearing cells (EMT-like transition). The purpose of these profiles was to identify differentially expressed genes that are regulated transcriptionally. Standard microarry-based gene expression profiles measure steady-state RNA but do not provide insight into underlying regulatory principles. NIAC-NTR-based gene expression profiling (Kenzelmann et al., PNAS, 2007) essentially enables the dissection of transcriptionally versus non-transcriptionally regulated genes within respective analysed time-frames. Briefly, NIAC-NTR relies on incorporation of 4sU (thio-uridine) into nascent RNA, which can subsequently be specifically isolated by custom-made columns. Total- and enriched (4sU-labeled) are then further processed for microarray gene expression profiling by standard procedures. This dataset complements previously released data of NIAC-NTR-based gene expression profiling of cells treated with TGF-b1 and 4sU for 2hrs [GSE23833].

Description
TGF-b1-stimulation induces an epithelial dedifferentiation-process, throughout which epithelial cell sheets disintegrate and gradually switch into fibroblastic-appearing cells (EMT-like transition). Several transcription factors, some of them being TGF-b1-responsive, are functionally involved in such a switch and affect epithelial differentiation and plasticity.

- Affymetrix Xenopus laevis Genome 2.0 Array (xlaevis2)
Description
The Notch signaling pathway functions in a number of processes during embryologic development, especially the maintenance or aquisition of cell fate. We purturb the Notch signalling pathway in embryonic Xenopus laevis in order to 1) better characterize the downstream targets of Notch signalling, and 2) determine the extent to which early embryos can recover from transient purturbations to critical signalling pathways, if at all.

Description
PTEN encodes a lipid phosphatase that is underexpressed in many cancers owing to deletions, mutations or gene silencing. PTEN dephosphorylates phosphatidylinositol 3,4,5-triphosphate (PIP3), thereby opposing the activity of class I phosphatidylinositol 3-kinases (PI3Ks) that mediate growth and survival factors signaling through PI3K effectors such as AKT and mTOR. To determine whether continued PTEN inactivation is required to maintain malignancy, we generated an RNAi-based transgenic mouse model that allows tetracycline-dependent regulation of PTEN in a time- and tissue-specific manner. Postnatal PTEN knockdown in the hematopoietic compartment produced highly disseminated T-cell leukemia (T-ALL). Surprisingly, reactivation of PTEN mainly reduced T-ALL dissemination but had little effect on tumor load in hematopoietic organs. Lymphoma infiltration into the intestine was dependent on CCR9 G-protein coupled receptor (GPCR) signaling, which was amplified by PTEN loss. Our results suggest that in the absence of PTEN, GPCRs may play an unanticipated role in driving tumor growth and invasion in an unsupportive environment. They further reveal that the role of PTEN loss in tumor maintenance is not invariant and can be influenced by the tissue microenvironment, thereby producing a form of intratumoral heterogeneity that is independent of cancer genotype.

Description
Obesity, an immense epidemic affecting approximately half a billion adults, has doubled in prevalence in the last several decades. Epidemiological data support that obesity due to intake of a high-fat, western diet increases the risk of colon cancer; however, the mechanisms underlying this risk remain unclear. Here, utilizing next generation RNA sequencing, we aimed to determine the high-fat diet mediated gene expression profile in mouse colon and the AOM/DSS model of colon cancer.
