- 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 Mouse Clariom S Array (clariomsmouse)
Description
Scope: As a result of population ageing, the number of Alzheimer’s disease (AD) patients has rapidly increased. There are many hypothesises on the pathogenesis of AD, but its detailed molecular mechanism is still unknown, and so no effective preventive or therapeutic measures have been established. Some reports showed a decrease in levels of norepinephrine (NE) has been suspected to be involved in the decline of cognitive function in AD patients and NE concentrations were decreased in postmortem AD patient brains. Tyr-Trp was identified as being the most effective dipeptide in enhancing norepinephrine (NE) synthesis and metabolism. And Tyr-Trp treatment ameliorated the short-term memory dysfunction in AD model mice caused by amyloid beta (Aβ) 25-35. So, the purpose of this study was to investigate the preventive or/and protective effects of Tyr-Trp administration in AD model mice.
Publication Title
Tyr-Trp administration facilitates brain norepinephrine metabolism and ameliorates a short-term memory deficit in a mouse model of Alzheimer's disease.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The mouse anterior-posterior (A-P) axis polarization is preceded by formation of the distal visceral endoderm (DVE). However, the mechanism of the emergence of DVE cells is not well understood. Here, we show by in vitro culturing of embryos immediately after implantation in micro-fabricated cavities (narrow; 90 micro-meter, wide; 180 miro-meter in diameter) that the external mechanical cues exerted on the embryo, i.e. cultured in the narrow cavity, are crucial for DVE formation as well as elongated egg cylinder shape. This implies that these developmental events immediately after implantation are not simply embryo-autonomous processes but require extrinsic mechanical factors. Further whole genome-wide gene expression profiles with DNA microarray revealed that no significant difference of transcripts were evident with or without mechanical cues except DVE-related markers. Thus, we propose that external mechanical cues rather than not specific molecular pathways can trigger the establishment of the A-P axis polarization, which is one of the fundamental proccesses of mammalian embryogenesis.
Publication Title
External mechanical cues trigger the establishment of the anterior-posterior axis in early mouse embryos.

Description
Ovarian clear cell carcinoma (OCCC) shows unique clinical features including an association with endometriosis and poor prognosis. We previously reported that the contents of endometriotic cysts, especially high concentrations of free iron, are a possible cause of OCCC carcinogenesis through iron-induced persistent oxidative stress. In this study, we conducted gene expression microarray analysis using 38 ovarian cancer cell lines and identified genes commonly expressed in both OCCC cell lines and clinical samples, which comprise an OCCC gene signature. The OCCC signature reproducibly predicts OCCC specimens in other microarray data sets, suggesting that this gene profile reflects the inherent biological characteristics of OCCC. The OCCC signature contains known markers of OCCC, such as hepatocyte nuclear factor-1b (HNF-1b) and versican (VCAN), and other genes that reflect oxidative stress. Expression of OCCC signature genes was induced by treatment of immortalized ovarian surface epithelial cells with the contents of endometriotic cysts, indicating that the OCCC signature is largely dependent on the tumor microenvironment. Induction of OCCC signature genes is at least in part epigenetically regulated, as we found hypomethylation of HNF-1b and VCAN in OCCC cell lines. This genomewide study indicates that the tumor microenvironment induces specific gene expression profiles that contribute to the development of distinct cancer subtypes.
