We report high-throughput profiling of gene expression from whole zebrafish ventricles. We profile mRNA in uninjured ventricles and those undergoing regeneration 14 days after genetic ablation. This study provides a framework for understanding transcriptional changes during adult models of regeneration. Overall design: Examination of gene expression in cardiomyocytes under different states of proliferation.

View SamplesVa24 invariant natural killer T (iNKT) cells are a subset of T lymphocytes implicated in the regulation of broad immune responses. They recognize lipid antigens presented by CD1d on antigen-presenting cells and induce both innate and adaptive immune responses, which enhance effective immunity against cancer, represent promising therapeutic target. However, reduced iNKT-cell numbers and function have been observed in many patients with cancer. To overcome this obstacle, we reprogramed human iNKT cells to pluripotency and then redifferentiated into regenerated iNKT cells in vitro through IL-7/IL-15-based optimized cytokine combination. They showed proliferation and IFN-? production in response to a-galactosylceramide, induced dendritic cell maturation and downstream activation of cancer antigen-specific cytotoxic T lymphocytes in vitro, and exhibited NKG2D- and DNAM-1-mediated natural killer celllike cytotoxicity against cancer cell lines. Their immunological features and availability in an unlimited supply from induced pluripotent stem cells offer the potential to develop effective immunotherapies against cancer. Overall design: Expression profile of the lymphocytes (n = 17) by highthrouput sequencing

View SamplesMouse embryonic fibroblasts deficient for p53 and expressing mutant RasV12 were infected with lentiviral constructs carrying short hairpin RNAs targeting ARF or a scrambled control. Four days post infection, cells were harvested for microarray analysis.

View SamplesThe 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.

View SamplesThe 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).

View SamplesStaphylococcus 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.

View SamplesGlucocorticoids (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.
