IlluminaHiSeq2000
Description
Human D14+ / CD16+ monocytes were treated with GPBAR1 agonists or controls, and were stimulated with interferon gamma and LPS. At 6 and 24 hours, the cells were profiled by RNAseq Overall design: 40 total samples, 5 per group with eight groups. Individual donors used for multiple comparisons, so paired analysis is possible. Control samples include unstimulated cells, and stimulated cells treated with vehicle control (DMSO).

Description
Analysis of transcriptomic fidelity between primary and pdx tumor. The hypothesis tested in the present study was that pdx can serve as high fidelity models of human cancer and guide longitudinal care. Results provide important information on the response of preservation of gene expression changes between the primary tumor and the first generation pdx.

- Affymetrix S. aureus Genome Array (saureus)
Description
Staphylococcus aureus is a highly adaptable human pathogen; therefore a constant search for new effective antibiotic compounds is being preformed. Gene expression profiling can be used to determine potential targets and mechanisms of action (MOA) of known or potential drugs. The goal of our study was a development of a focused transcriptome platform to be used for confirming the MOA of new chemical entities which are designed as inhibitors of Mur ligases. A model transcriptional profile was set up for well described inhibitor of MurA ligase, fosfomycin. Moreover, we wanted to identify the pathways and processes primarily affected by this compound. S. aureus ATCC 29213 cells were treated with low concentrations of fosfomycin (1 and 4 g/ml, respectively) and harvested at 10, 20 and 40 minutes after treatment, respectively. RNA was isolated, transcribed, labeled and hybridized to S. aureus GeneChips, representing approximately 3000 S. aureus genes.

Description
The comparison of trancriptomes was part of the study by Pfender, Kuznetsov, Pasternak et al, titled: "Live imaging RNAi screen reveals genes essential for meiosis in mammalian oocytes". The goal was to check if the oocytes cultured in vitro in follicles (for RNAi studies) correspond to real gametes obtained directly from mice (in vivo). Apart from functional experiments showing that they can be fertilized and develop into an embryo, we also compared transcriptomes of those oocytes. Overall design: 3 samples of 50 oocytes were collected for both groups of in vitro and in vivo grown oocytes.

Description
The study entails novel bio-marker discovery of Tumor Aggressive Grade signature (TAGs) genes and their role in recurrence free survival of breast cancer (BC) patients. Current BC dataset was used for co-expression analysis of TAGs genes and their role in BC progression. Additionally, recent findings have suggested an importance of structural organization of sense-antisense gene pairs (SAGPs) for transcription, post-transcriptional and post-translational events and their associations with cancer and disease. We studied SAGPs in which both gene partners are protein encoding genes (coding-coding SAGPs), their role in human BC development and demonstrated their potential for BC stratification and prognosis. Based on gene expression and correlation analyses we identified the robust set of breast cancer-relevant SAGPs (BCR-SAGPs). We isolated and characterized the sense-antisense gene signature (SAGS) and evaluated its prognostic potential in various gene expression datasets comprising 1161 BC patients. The methods used included the Cox proportional survival analysis, statistical analysis of clinicopathologic parameters and differential gene expression. The SAGS was effective in identification of BC patients with the most aggressive disease. Independently, we validated the SAGS using 58 RNA samples of breast cancer tumors purchased from OriGene Technologies (Rockville, MD).

Description
Glucocorticoids (GCs) are essential steroid hormones that regulate the immune system. GCs have been widely used to treat various inflammation disorders and auto-immune diseases, due to their potent immune repression properties. Overall design: HeLa cells were cultured with DMEM plus 10% charcoal-stripped FBS. HeLa cells were treated in the presence of 100 nM triamcinolone acetonide (TA) for 4 hours. Cells were then collected for RNA-seq.

Glucocorticoids (GCs) are essential steroid hormones that regulate the immune system. GCs have been widely used to treat various inflammation disorders and auto-immune diseases, due to their potent immune repression properties. Overall design: Monocytes from healthy donors were cultured in the presence of 100 nM triamcinolone acetonide (TA), 100 nM Dexamethasone (Dex) or 100 nM Prednisolone (Pred) for 4 hours. Cells were then collected for RNA-seq.

Description
Dyskeratosis congenita (DC) is an inherited multi-system disorder, characterized by oral leukoplakia, nail dystrophy, and abnormal skin pigmentation, as well as high rates of bone marrow failure, solid tumors, and other medical problems such as osteopenia. DC and telomere biology disorders (collectively referred to as TBD here) are caused by germline mutations in telomere biology genes leading to very short telomeres and limited proliferative potential of hematopoietic stem cells. We found that skeletal stem cells (SSCs) within the bone marrow stromal cell population (BMSCs, also known as bone marrow-derived mesenchymal stem cells), may contribute to the hematological phenotype.
