Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Inhibition of calcineurin-NFAT pathway at the early stage can block somatic cell reprogramming. In order to study how the calcineurin-NFAT pathway contributes to the early stage of reprogramming, we designed this microarray experiment and tried to find out which genes or signalings were changed after inhibition of calcineurin-NFAT signaling by CSA (a specific inhibitor of calcineurin-NFAT pathway).

Description
Selenium (Se) is an important trace element for many organisms and is incorporated into selenoproteins as selenocysteine (Sec). In eukaryotes, selenophosphate synthetase SPS2 is essential for Sec biosynthesis. In recent years, genetic disruptions of both Sec biosynthesis genes and selenoprotein genes have been investigated in different animal models, which provide important clues for understanding the Se metabolism and function in these organisms. However, a systematic study on the knockdown of SPS2 has not been performed in vivo.

Description
The young panicles 2 cm length were used for expression analysis in well watered control and drought stressed treatment. The panicle samples from biological replicates of six rice varieties were obtained in three independent experiments. The expression profiles were generated using Affymetrix rice genome arrays.

Description
Unraveling the mechanisms underlying early neural differentiation of ESCs is crucial to the cell-based therapies of neurodegenerate diseases. Neural fate acquisition is proposed to be controlled by a default mechanism, for which the molecular regulation is not well understood. In this study, we investigated the functional roles of Mediator Med23 in pluripotency and lineage commitment of embryonic stem cells (ESCs). Unexpectedly we found that, despite the largely unchanged pluripotency and self-renewal of ESCs, Med23-depletion rendered the cells prone to neural differentiation in different differentiation assays. Knockdown of other Mediator subunit, Med1 or Med15, did not alter the neural differentiation of ESCs; and Med15 knockdown selectively inhibited endoderm differentiation, suggesting the specificity of cell fate control by distinctive Mediator subunits. Gene profiling revealed that Med23-depletion attenuated the BMP signaling in ESCs. Mechanistically, MED23 modulated Bmp4 expression by controlling the activity of ETS1 that is involved in the Bmp4 promoter-enhancer communication. Interestingly, Med23 knockdown in zebrafish embryos also enhanced the neural development at early embryogenesis, which could be reversible by coinjection of bmp4 mRNA. Taken together, our study reveals an intrinsic, restrictive role of MED23 in early neural development, thus providing new molecular insights for neural fate determination.

Description
Dietary restriction (DR) is the most powerful natural means to extend lifespan. Here we obtain temporally resolved transcriptomes during calorie restriction and intermittent fasting in Caenorhabditis elegans, and find that early and late responses involve metabolism and cell cycle/DNA damage, respectively.

Description
The roles of histone demethylases (HDMs) for the establishment and maintenance of the pluripotent state are incompletely defined. Here, we show that JmjC domain-containing protein 1c (Jmjd1c), a putative histone H3 Lys 9 (H3K9) demethylase, is required for mouse embryonic stem cell (ESC) self-renewal. To understand how Jmjd1c knockdown (KD) and resultant changes in the H3K9 methylations would affect ESCs at a global gene expression level, we compared the whole genome transcriptomes between the control and Jmjd1c KD ESCs (6 samples, including 2 shNT control samples and 4 shJmjd1c samples, 2 from #3 and 2 from #4 shRNA, respectively) using affymetrix microarray.
