Description
We isolated and selected intestinal adenoma organoids from villin-CreER; Apcflox/flox and villin-CreER; Apcflox/flox; Prox1flox/flox mice and added tamoxifen to induce the deletion of the Apc and Prox1 genes in the intestinal epitheliul ex vivo. Microarray experiments were carried out 7 days after the addition of tamoxifen.

Description
Cell lines derived from NK cell neoplasms were characterized using RNA sequencing and high-throughput drug sensitivity profiling to identify therapeutically actionable drivers in malignant NK cells. Overall design: RNA sequencing data was obtained from natural killer and T cell lines for gene expression profiling and mutation detection in parallel with drug sensitivity profiling. The ''NK_cell_line_GEO_drug_sensitivity.txt'' contains drug sensitivity scores of cell lines screened using 459 compounds. Breifly, compounds were preprinted on 384-well plates (Corning) in five different concentrations covering a 10,000-fold concentration range with an acoustic liquid handling device (Echo 550, Labcyte Inc.) and dissolved in 5 l culture medium on a shaker for 10 min. 20 l of single-cell suspension of cell lines (3,000 cells per well) were dispensed using Multi-Drop Combi peristaltic dispenser (Thermo Scientific). Plates were incubated at 37 C and 5% CO2 for 72 h after which cell viability was measured using CellTiter-Glo 2.0 reagent (Promega) according to the manufacturer s instructions with a Pherastar FS plate reader (BMG Labtech). Cell viability luminescence data were normalized to DMSO-only wells (negative control) and 100 mM benzethonium chloride-containing wells (positive control). The data were quantified using the drug sensitivity score (DSS) (Yadav et al., Scientific Reports 2014).

Description
Anopheles gambiae,the primary African malarial mosquito, exhibits numerous behaviors that are under diel and circadian control, including locomotor activity, swarming, mating, host seeking, eclosion, egg laying and sugar feeding. However, little has been performed to elucidate the molecular basis for these daily rhythms. To study how gene expression is globally regulated by diel and circadian mechanisms, we have undertaken a DNA microarray analysis ofA. gambiaehead and bodies under 12:12 light:dark cycle (LD) and constant dark (DD, free-running) conditions. Zeitgeber Time (ZT) with ZT12 defined as time of lights OFF under the light:dark cycle, and ZT0 defined as end of the dawn transition. Circadian Time (CT) with CT0 defined as subjective dawn, inferred from ZT0 of the previous light:dark cycle.

Description
Chronic inflammation during placental malaria (PM) caused by Plasmodium falciparum is most frequent in first-time mothers and is associated with poor maternal and fetal outcomes. In the first genome wide analysis of the local human response to sequestered malaria parasites, we identified genes associated with chronic PM, then localized the corresponding proteins and immune cell subsets in placental cryosections.

Description
Estrogen-related receptor (ERR) alpha is an orphan nuclear receptor highly expressed in the kidneys. ERRalpha is implicated in renal sodium and potassium homeostasis and blood pressure regulation. We used microarray analysis to identify differentially expressed genes in ERR alpha knockout mice kidneys versus wild-type. The results provide insight on the roles of ERRalpha in the kidney.

Description
Purpose: we tested the hypothesis that Hltf deletion in placenta either caused or exacerbated neonatal hypoglycemia via Hif-1a regulation of nutrient transporters. Methods: Individual samples [1 term placenta/sample x 5 biological replicates for test and control littermate female mice = 10 total samples] were flash frozen and sent to Otogenetics Corp. (Norcross, GA) for RNA-seq assays. Paired-end 100 nucleotide reads were aligned to genomic assembly mm10 and analyzed using the platform provided by DNAnexus, Inc. (Mountain View, CA). Results: There was no measureable evidence of uteroplacental dysfunction or fetal compromise. Conclusion: Our study is the first to show only the truncated Hltf isoform is expressed in E18.5 term placenta, and we identified a functional link between alternative splicing of Hltf and immunosuppression at the feto-maternal interface. Overall design: Placental mRNA profiles of E18.5 term placenta from five wild type control and five Hltf null mouse samples were generated by deep sequencing by Illumina HiSeq2000/2500.

Description
We describe a chemical method to label and purify 4-thiouridine (s4U) -containing RNA. We demonstrate that methanethiolsulfonate (MTS) reagents form disulfide bonds with s4U more efficiently than the commonly used HPDP-biotin, leading to higher yields and less biased enrichment. This increase in efficiency allowed us to use s4U-labeling to study global microRNA (miRNA) turnover in proliferating cultured human cells without perturbing global miRNA levels or the miRNA processing machinery. This improved chemistry will enhance methods that depend on tracking different populations of RNA such as 4-thiouridine-tagging to study tissue-specific transcription and dynamic transcriptome analysis (DTA) to study RNA turnover. Overall design: s4U metabolic labeling of RNA in 293T cells, followed by biochemical enrichment of labeled RNA with two biotinylation reagents, RNAs >200nt and miRNAs in separate experiments
