Illumina HumanHT-12 V4.0 expression beadchip
Description
This study aimed to generate a new panel of comprehensively, genomically characterized high-grade serous ovarian carcinoma (HGSOC) cell line and xenograft models. Multidimensional genomic data were generated and compared between cell lines/xenografts and the tumours they were derived from, indicating the cell lines/xenografts are highly similar to their patient-matched tumours. Cell line/xenograft data were also compared to TCGA ovarian tumours to show the cell lines are good models of clinical HGSOC.

Illumina HiSeq 1500
Description
PEST-domain-enriched tyrosine phosphatase (PEP) is a cytoplasmic protein tyrosine phosphatase that regulates immune cell functions, including mast cell functions. Using bone marrow derived mast cells (BMMCs) from PEP+/+ and PEP-/- mice, RNA-seq data showed that dinitrophenol (DNP) - activated PEP-/- BMMCs have misregulated gene expression, with some cytokine/chemokine genes (eg.TNFa, IL13, CSF2) showing reduced gene expression in the dinitrophenol (DNP) - activated PEP-/- BMMCs compared to (DNP)-activated PEP+/+ BMMCs. Also, the ability of the glucocorticoid dexamethasone (Dex) to negatively regulate DNP - induced COX-2 gene expression in PEP-/- BMMCs was inhibited compared to the PEP+/+ BMMCs. Overall design: Biological replicates are sequenced and analyzed. The samples are either wild-type or mutant for PEP and cells were sensitized with Ig-E, activated with Dinitrophenol and glucocorticoid treatment done with Dexamethasone.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Saccharomyces cerevisiae flocculation occurs when fermentable sugars are limiting and is therefore considered as a way to enhance the survival chance of Flo-expressing yeast cells. In this paper, the role of Flo1p in mating was demonstrated by showing that the mating efficiency, which contributes to the increased survival rate as well by generating genetic variability, is increased when cells flocculate. This was revealed by liquid growth experiments in a low shear environment and differential transcriptome analysis of FLO1 expressing cells compared to the non-flocculent wild-type cells. The results show that a floc provides a uniquely organized multicellular ultrastructure that provides a suitable microenvironment to induce and perform cell conjugation.

Description
Besides the established selection criteria based on embryo morphology and blastomere number, new parameters for embryo viability are needed to improve the clinical outcome of in vitro fertilization (IVF) and more particular of elective single embryo transfer (eSET). The aim of the study was to analyse genome-wide whether the embryo viability was reflected by the expression of genes in the oocyte surrounding cumulus cells. Early cleavage (EC) was chosen as a parameter for embryo viability.

Description
During pneumonic plague, the bacterium Yersinia pestis elicits the development of inflammatory lung lesions that continue to expand throughout infection. This lesion development and persistence is poorly understood. Here, we examine spatially distinct regions of lung lesions using laser capture microdissection and RNAseq analysis to identify transcriptional differences between lesion microenvironments. We show that cellular pathways involved in leukocyte migration and apoptosis are down regulated in the center of lung lesions compared to the periphery. Probing for the bacterial factor(s) important for the alteration in neutrophil survival, we show both in vitro and in vivo that Y. pestis increases neutrophil survival in a manner that is dependent on the type-III secretion system effector YopM. This research explores the complexity of spatially distinct host - microbe interactions and emphasizes the importance of cell relevance in assays in order to fully understand Y. pestis virulence. Overall design: We examine spatially distinct regions of lung lesions using laser capture microdissection and RNAseq analysis to identify transcriptional differences between lesion microenvironments. Sample types: uninfected BM-PMN, infected BM-PMN, lesion periphery, lesion center.

Description
Venous thromboembolism (VTE) is a major cause of morbidity and mortality. Pulmonary embolism is a life threatening manifestation of VTE that occurs in at least half the patients on presentation. In addition, VTE recurs in up to 30% of patients after a standard course of anticoagulation, and there is not a reliable way of predicting recurrence. We investigated whether gene expression profiles of whole blood could distinguish patients with VTE from healthy controls, single VTE from those with recurrence, and DVT alone from those with PE. 70 adults with VTE on warfarin and 63 healthy controls were studied. Patients with antiphospholipid syndrome or cancer were excluded. Blood was collected in PAXgene tubes, RNA isolated, and gene expression profiles obtained using Affymetrix arrays. We developed a 50 gene model that distinguished healthy controls from subjects with VTE with excellent receiver operating characteristics (AUC 0.94; P < 0.0001). We also discovered a separate 50 gene model that distinguished subjects with a single VTE from those with recurrent VTE with good receiver operating characteristics (AUC 0.75; P=0.008). In contrast, we were unable to distinguish subjects with DVT from those with PE using gene expression profiles. Gene expression profiles of whole blood can distinguish subjects with VTE from healthy controls and subjects with a single VTE from those with recurrence. Additional studies should be performed to validate these results and develop diagnostic tests. Gene expression profiling is likely translatable to other thrombotic disorders(e.g., patients with cancer and VTE).

Description
Two nutrient sensing and regulatory pathways, the general amino acid control (GAAC) and the target of rapamycin (TOR), control yeast growth and metabolism in response to changes in nutrient availability. Starvation for amino acids activates the GAAC pathway, involving Gcn2p phosphorylation of eIF2 and preferential translation of GCN4, a transcription activator of genes involved in amino acid metabolism. TOR senses nitrogen availability and regulates gene expression through transcription factors, such as Gln3p. We used microarray analyses to address the integration of the GAAC and TOR pathways in directing the yeast transcriptome in response to amino acid starvation and rapamycin treatment. Of the ~2500 genes whose expression was changed by 2-fold or greater, Gcn4p and Gln3p were required for 542 and 657 genes, respectively. While Gcn4p activates a common core of 57 genes in response to amino acid starvation or rapamycin treatment, the different stress arrangements allow for variations in Gcn4p-directed transcription. With few exceptions, genes requiring Gcn2p eIF2 kinase for induced expression also required Gcn4p, emphasizing the role of Gcn2p as an upstream activator of Gcn4p-directed transcription. There is also significant coordination between the GAAC and TOR pathways, with Gcn4p being required for activation of more genes during rapamycin treatment than Gln3p. Importantly, TOR regulates the GAAC-directed transcription of genes required for assimilation of nitrogen sources, such as -amino-butyric acid. Therefore, yeast has integrated gene expression responses to amino acid abundance and nitrogen source quality through the control of Gcn2p phosphorylation of eIF2 and GCN4 translation.
