Description
We undertook an integrative technological approach to compare miRNA detection capability of three high-throughput commercial platforms. Overall design: We artificially introduced human precursor, 2’-O-methyl modified and mature spiked-in miRNAs in a controlled fashion into native human placenta total RNA.
Publication Title
Differences in microRNA detection levels are technology and sequence dependent.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Med26 is a subunit of the Human Mediator complex. The Mediator complex is an evolutionarily conserved coregulatory complex that interacts with RNA polymerase II to regulate gene expression. In metazoa, Mediator is composed of some 30 distinct subunits. Mediator exists in multiple, functionally distinct forms that share a common core of subunits and can be distinguished by the presence or absence of a kinase module composed of Med12, Med13, Cdk8, and Cyclin C. In higher eukaryotes, a subset of Mediator complexes is associated with an additional subunit, Med26. This Med26-containing Mediator copurifies from cells with little or no kinase module, but near-stoichiometric Pol II. Evidence suggests that Med26-containing Mediator plays a key role in transcriptional activation however, the mechanism(s) by which Med26 contributes to this process are not known. To identify Med26 target genes, we used Affymetrix U133A plus 2.0 expression arrays to analyze mRNA expression in 293T cells from which Med26 had been depleted by transient transfection by each of three different siRNAs.
Publication Title
Human mediator subunit MED26 functions as a docking site for transcription elongation factors.

Description
This study uses spiked-in transcript in order to compares various bioinformatics approaches and tools to assemble, quantify abundance and detect differentially expressed transcripts using RNA-Seq data. Mouse total RNA seq was extracted from embryonic stem cells (ES) before (designated as day 0) and four days after the addition of retinoic acid. 48 spikes were made in vitro from plasmid constructs and added to the total RNA in different concentrations (each mix has a set of different spike concentrations, see paper''s method). We found that detection of differential expression at the gene level is acceptable, yet on the transcript-isofom level all tools tested were lacking accuracy and precision. Overall design: Mouse total RNA was extracted from embryonic stem cells (ES) before (designated as day 0) and four days after the addition of retinoic acid (RA) (designated as day 4). Mouse spike-ins consisting of 48 different mouse RNA transcripts were generated in vitro from plasmid constructs and added to the total RNA. 23 of the spike-ins originate from 10 different locus regions, so that each locus is represented by at least two different transcripts. The remaining 25 spike-ins represent different loci.

Description
Vemurafenib is a BRAF inhibitor with specificity for the most common BRAF mutant encountered in melanomas (BRAFV600E). Vemurafenib suppresses the proliferation of BRAF mutant human melanoma cells by suppressing downstream activation of the MEK/ERK mitogen activated protein kinases.

Description
Identification of intrathymic Eomes+ natural Th1 cells creates a novel idea that there is more than one way for the generation of innate CD4 T cells. To more deeply characterize this type of innate T cells, we compared the gene expression profile between nTh1 cells generated in CIITAtg mice and classic Th1 cells differentiated from naive CD4 T cells in Th1-polarizing condition.

Description
Our study demonstrated that e-cigarettes, both with and without nicotine, induced sex-dependent gene expression change. This RNA-seq study examined the expression profiles of brain frontal cortex samples from mice exposed to classic tobacco flavored bluâ„¢ e-cigarettes during gestation and lactation. Overall design: Brains were extracted and sectioned from ~1-month-old male and female offspring the week following exposure, RNA was isolated and purified from frontal cotrex tissues, and gene expression profiles were analyzed by RNA Sequencing.

Description
Human cytomegalovirus (HCMV) induces pro-inflammatory monocytes following infection and we have evidence that phosphatidylinositol 3-kinase [PI(3)K] is a key mediator in this activation. To begin to address how this signalling pathway is responsible for the functional changes in infected monocytes, we examined the role this pathway played in the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of genes were regulated in a PI(3)K-dependent manner, identifying this pathway as a key cellular control point in the conversion of monocytes to an activated pro-inflammatory state following HCMV infection.
Publication Title
PI3K-dependent upregulation of Mcl-1 by human cytomegalovirus is mediated by epidermal growth factor receptor and inhibits apoptosis in short-lived monocytes.
