Illumina HiSeq 2000
Description
Transcriptome analysis of cold-treated leaves (unifoliates) of soybean seedlings were performed. RNAseq analysis was performed using two lanes on a Illumina HiSeq2000 and sequenced on a 100bp, paired-end run. Overall design: Two-weeks old soybean (c.v. 'Williams 82') seedlings were cold-treated (4 °C) starting at 4 h after the lights turned on (Zeitgeber Time, ZT4 h, 18 hours light/6 hours dark) and maintaining 4 °C continuously with the light cycle till harvest time (0, 1, and 24 hours). All treatment samples were performed in triplicate (with n=6 plants per replication).

Description
The possible benefits of selenium (Se) supplementation are currently under investigation for prevention of certain cancers and treatment of neurological disorders. Little is known concerning the response of the brain to increased dietary Se under conditions of Se sufficiency, despite the majority of Se supplementation trials occurring in healthy subjects considered Se sufficient. We evaluated the transcriptional response of the zebrafish (Danio rerio) brain to supplementation with nutritionally relevant levels of dietary Se (sodium selenite) during conditions of assumed Se sufficiency.

Description
Domesticated animal populations often show profound reductions in predator avoidance and fear-related behavior compared to wild populations. These reductions are remarkably consistent and have been observed in a diverse array of taxa including fish, birds, and mammals. Experiments conducted in common environments indicate that these behavioral differences have a genetic basis. In this study, we quantified differences in fear-related behavior between wild and domesticated zebrafish strains and used microarray analysis to identify genes that may be associated with this variation.

Description
The undifferentiated state of pluripotent stem cells depends heavily on the culture conditions. We show that a unique combination of small molecules, SMC4, added to culture conditions converts primed pluripotent stem cells to a more nave state. By conducting Affymetix analysis we show of majority of lineage markers are repressed in SMC4 culture.

Description
Erythropoiesis in mammals replenishes the circulating red blood cell (RBC) pool from hematopoietic stem/progenitor cells (HSPCs). Two distinct erythropoietic programs have been described. In the first trimester, hematopoietic precursors in the fetal yolk sac follow a primitive pattern of erythropoiesis. However, in the second trimester, hematopoietic stem cells (HSCs) from the fetal liver and later from the bone marrow differentiate by a definitive program of erythropoiesis to yield enucleated erythrocytes. RBCs can also be derived from human induced pluripotent stem cells (hiPSCs) and can express many of the red cell proteins required for normal erythrocyte function, presaging in vitro RBC production for clinical use. However, expansion and enucleation from hiPSCs is less efficient than with erythroblasts (EBs) derived from adult or cord blood progenitors. We hypothesized that substantial differential gene expression during erythroid development from hiPSCs compared to that from adult blood or cord blood precursors could account for these hitherto unexplained differences in proliferation and enucleation. We have therefore grown EBs from human adult and cord blood progenitors and from hiPSCs. Gene expression during erythroid culture from each erythroblast source was analyzed using algorithms designed to cluster co-expressed genes in an unsupervised manner and the function of differentially expressed genes explored by gene ontology. Using these methods we identify specific patterns of gene regulation for adult- and cord- derived EBs, regardless of the medium used, that are substantially distinct from those observed during the differentiation of EBs from hiPSC progenitors which largely follows a pattern of primitive erythropoiesis.

Description
We used microarray analyses in adult female zebrafish (Danio rerio) to identify metabolic pathways regulated by starvation in two key organs that 1) serve biosynthetic and energy mobilizing functions (liver) and 2) consume energy and direct behavioral responses (brain). Starvation affected the expression of 574 transcripts in the liver, indicating an overall decrease in metabolic activity, reduced lipid metabolism, protein biosynthesis and proteolysis, and cellular respiration, and increased gluconeogenesis. Starvation also regulated expression of many components of the Unfolded Protein Response, the first such report in a species other than yeast (Saccharomyces cerevisiae) and mice (Mus musculus). The response of the zebrafish hepatic transcriptome to starvation was strikingly similar to that of rainbow trout (Oncorhynchus mykiss), but very different from common carp (Cyprinus carpio) and mouse. The transcriptome of zebrafish whole brain was much less affected than the liver, with only two differentially expressed genes, both down-regulated. Down-regulation of one of these genes, matrix metalloproteinase 9 (mmp9), suggests increased inhibition of apoptosis (neuroprotection) and decreased restructuring of the extracellular matrix in the brain of starved zebrafish. The low level of response in the transcriptome of whole zebrafish brain agrees with observations that the brain is metabolically protected compared to the rest of the body.

Description
Human pluripotent stem cells in culture are often associated with the prime state which represents a more developed state relative to the nave state which is often associated with the inner cell mass and thought to have the potential to give rise to all cell types. We have developed a small molecule-driven cocktail FMM that maintains human pluripotent stem cells in a state similar to the naive state as defined by several properties including gene expression profile.
