Description
Using RNA-Seq, we reported novel findings in the comparison of transcriptome profiles of isogenic HMDM and IPSDM during differentiation and polarization. First, IPSDM lost expression of pluripotency markers, had remarkably distinct gene expression profiles relative to precursor iPSCs, and had largely similar gene expression as HMDM. Second, macrophage polarization to M1 was associated with a dramatic change in the transcriptome; expression profiles of IPSDM- and HMDM-derived M1 lines were highly correlated with each other but much less so with their respective IPSDM and HMDM precursors. Third, M2-HMDM lines had limited difference in gene expression compared to their non-polarized precursors, likely due to the known M2-like phenotype of M-CSF differentiated macrophages and their similarity to the IL-4 derived M2 phenotype Finally, through RNA-Seq we identified many new genes modulated during polarization in both HMDM and IPSDM thus providing novel, and potentially regulatory, candidates that warrant further study. Overall design: iPS, IPSDM (including M1/M2) and HMDM (including M1/M2)cells were sequenced by Illumina HiSeq 2000 with poly-A selection

Affymetrix Bovine Genome Array (bovine)
Description
Sexual dimorphism in mammals is mostly attributable to sex-related hormonal differences in fetal and adult tissues; however, this may not be the sole determinant. Though genetically-identical for autosomal chromosomes, male and female preimplantation embryos could display sex-specific transcriptional regulation which can only be attributted to the differences in sexual chromosome dosage.

Sex determines the expression level of one third of the actively expressed genes in bovine blastocysts.

Description
We sought to determine the impact of chorioamnionitis exposure on term neonatal monocyte transcription. RNA-seq was performed on term healthy and chorioamnionitis-exposed umbilical cord blood purified CD14+ monocytes under unstimulated and LPS stimulated conditions. Overall design: RNA-seq on 11 samples with 2-3 replicates per exposure/stimulation group (each replicate contains 3 pooled samples)
Publication Title
Chorioamnionitis exposure remodels the unique histone modification landscape of neonatal monocytes and alters the expression of immune pathway genes.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
In bacteria, the biosynthesis of cysteine is accomplished by two enzymes that are encoged by the cysK and cysM genes. CysM is also able to incorporate thiosulfate to produce S-sulfocysteine. In plant cells, the biosynthesis of cysteine occurs in the cytosol, mitochondria and chloroplasts. Chloroplasts contain two O-acetylserine(thiol)lyase homologs, which are encoded by the OAS-B and CS26 genes. An in vitro enzymatic analysis of the recombinant CS26 protein demonstrated that this isoform possesses S-sulfocysteine synthase activity and lacks O-acetylserine(thiol)lyase activity. In vivo functional analysis of this enzyme in knockout mutants demonstrated that mutation of cs26 suppressed the S-sulfocysteine synthase activity that was detected in wild type; furthermore, the mutants exhibited a growth phenotype, but penetrance depended on the light regime. The cs26 mutant plants also had reductions in chlorophyll content and photosynthetic activity (neither of which were observed in oas-b mutants), as well as elevated glutathione levels. However, cs26 leaves were not able to properly detoxify ROS, which accumulated to high levels under long-day growth conditions. The transcriptional profile of the cs26 mutant revealed that the mutation had a pleiotropic effect on many cellular and metabolic processes. Our finding reveals that S-sulfocysteine and the activity of S-sulfocysteine synthase play an important role in chloroplast function and are essential for light-dependent redox regulation within the chloroplast.

Arabidopsis S-sulfocysteine synthase activity is essential for chloroplast function and long-day light-dependent redox control.

Description
Glycolytic Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) catalyzes the conversion of glyceraldehyde 3-phospate to 1,3-bisphosphoglycerate by coupling with the reduction of NAD+ to NADH. We generated mutants of the Arabidopsis plastidial GAPDH isoforms (At1g79530, At1g16300; GAPCp1, GAPCp2). gapcp double mutants (gapcp1 gapcp2) display a drastic phenotype of arrested root development and sterility.Complex interactions occurring between ABA and sugar signal transduction pathways have been shown, but the molecular mechanisms connecting both pathways are not well understood. Since we found drastic carbohydrate changes in gapcp1 gapcp2, we studied their response to ABA. by performing a microarray analysis comparing gapcp1 gapcp2 and wild type seedlings after a long term treatment with ABA.

Description
To understand the funtion of Colorectal cancer GWAS results, we perform a comprehensive analysis using biofeatures of HCT116 colon cancer cell line and got a list of risk-asscociated SNP. Risk-associated SNP are likely exerting their effects through promoters or enhancer. In order to understand the importance of the genes with risk-associated SNP in their promoters and enhancers'' putatively targeted genes, we did a comparison of these genes between HCT116 colon cancer cell and normal colon and try to understand their function Overall design: Two biological replicates of HCT116 were compared to the data of two normal colon samples already deposited in GEO (GSM1010974 and GSM1010942).
