Description
We sequenced mRNA from transverse slices of embryos from a variety of D. melanogaster mutants (bicoid over-expression, bicoid knockdown, hunchback knocdown, and zelda mutant) at the blastoderm stage to determine genome-wide patterns of gene expression. Overall design: mRNA from transverse sections of single D. melanogaster embryos mutant for patterning TFs was sequenced.

Description
We sequenced mRNA according to several library prep protocols with known mixtures of two species of Drosophila in order to establish linear response in each protocol. Overall design: For each library prep protocol, mixtures with 0%, 5%, 10%, and 20% D. virilis total RNA was prepared, then libraries prepared according to instructions.
Publication Title
Low-cost, low-input RNA-seq protocols perform nearly as well as high-input protocols.

Description
We report that TAF3, a TBP-associated core promoter factor, is highly enriched in ES cells. In addition to its role in the core promoter recognition complex TFIID, genome-wide binding studies reveal that TAF3 localizes to chromosomal regions bound by CTCF and cohesin. Enrichment for TAF3/CTCF/cohesin bound regions distinguishes TAF3-activated from TAF3-repressed genes. Our findings support a new role of TAF3 in mediating long-range chromatin regulatory interactions to safeguard the finely-balanced transcriptional programs that give rise to pluripotency. Overall design: Comparison of genome-wide expression patterns between TAF3-knockdown and WT embryonic stem cells using mRNA-Seq. Significantly differentially expressed protein-coding genes were identified by comparing control and knock-down samples at each timepoint (ES, embryoid body day 3 (EB3), EB6). Single and paired-end samples were combined at each timepoint, resulting in 3 tests for each gene (based on 8, 4, 4 independent measurements at ES ,EB3, EB6, respectively).

Description
We examined the effects of TNFa and Spt5, the major DSIF subunit, on nascent and mature transcripts using RNA-Seq of chromatin-associated and cytoplasmic transcripts. Overall design: RNA was extracted from the cytosolic and chromatin fractions of control and Spt5 KD cells that were treated with TNFa for 1 hour

Description
The Wnt signaling pathway plays a fundamental role during the development of metazoans, where it functions in the regulation of diverse processes including cell fate specification, cell migration, and stem cell renewal. Activation of the beta-catenin dependent or canonical Wnt signaling pathway upregulates expression of Wnt target genes to mediate an appropriate cellular response. In the nematode C. elegans, a Wnt signaling pathway similar to the canonical pathway regulates several processes during larval development, however few target genes of this pathway have been identified. To address this deficit, we conditionally activated Wnt signaling in living animals during a defined stage of larval life by expressing a dominant, activated beta-catenin protein, then used microarray analysis to identify genes showing altered expression compared to control animals. In this way we identified 166 differentially expressed genes, of which 104 were upregulated. A subset of the upregulated genes were validated by qPCR and showed altered expression in Wnt pathway mutants with decreased or increased Wnt signaling; we consider these genes to be candidate Wnt pathway targets in the C. elegans hermaphrodite larva. Amongst these was a group of 6 genes, including the cuticular collagen genes, bli-1 col-38, col-49 and col-71, that show a peak of expression in the mid L4 stage during normal development. The L4 expression of these genes suggests they may be expressed for use in the adult cuticle, and consistent with this, reduction of function for several of the genes leads to phenotypes suggestive of defects in cuticle function or integrity. Therefore this work has identified a large number of putative Wnt pathway target genes during larval life, including a small subset of Wnt-regulated collagen genes that may function in synthesis of the adult cuticle.

Description
As RIG-I activation induces potent IFN-I responses,we analyzed the role of IFN-I in intestinal tissue protection and prevention of GVHD. We performed RNA sequencing with tissue samples from SI of WT mice that received TBI -/+ previous 3pRNA treatment and -/+ antibody-mediated blockade of IFNAR. Application of 3pRNA before TBI resulted in a significant increase of IFN-inducible genes in the SI as compared to solely irradiated mice. Blockade of IFNAR signaling abrogated 3pRNA-mediated up-regulation of IFN-induced genes, demonstrating that RIG-I-induced gene-regulation depends on IFN-I. Overall design: Balb/c mice were solely irradiated (9Gy) (n=3), pretreated with Rig-I agonist 3pRNA prior (d-1) to irradiation (n=3) or pre-treated with 3pRNA (d-1) + anti-IFNaR1 blocking antibody (d-2) prior to irradiation (n=3). RNA from small intestines was isolated 12h after irradiation and used for RNA sequencing.

Description
Calyx of Held giant presynaptic terminals in the medial nucleus of the trapezoid body of the auditory brainstem form axosomatic synapses that have advanced to one of the best-studied synaptic system of the mammalian brain. As the auditory system matures and adjusts to high fidelity synaptic transmission, the calyx undergoes extensive structural and functional changes: it is formed around postnatal day 3 (P3), achieves immature function until hearing onset around P10 and can be considered mature from P21 onwards. This setting provides the unique opportunity to examine the repertoire of genes driving synaptic structure and function.
