Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
The formation of neuronal connections requires the precise guidance of developing axons towards their targets. In the Drosophila visual system, photoreceptor neurons (R cells) project from the eye into the brain. These cells are grouped into some 750 clusters comprised of eight photoreceptors or R-cells each. R cells fall into three classes, R1-R6, R7 and R8. Posterior R8 cells are the first to project axons into the brain. How these axons select a specific pathway is not known.

Description
Purpose: Quiescence is a state of reversible cell cycle exit. Levels of polyadenylation factors decreases when proliferating cells become quiescent. The goals of this study are to determine the differential use of polyadenylation sites (changes in alternative polyadenylation) in quiescent vs. proliferating cells and also upon knockdown of polyadenylation factors. Methods: Two biological replicates of human dermal fibroblasts (12-1 and 12-3) were used for polyadeylation-site enriched RNA-seq on an Illumina HiSeq 2500 to compare quiescent vs. proliferating cells and polyadenylation factor knockdown vs. control cells. The reads were aligned to the human genome (hg19) uisng Tophat (2.0.14). The resulting bam files were used as an input to a python script provided by Gruber et al. (PMID: 27382025) to determine the counts for each polyadenylation site. Results: We observed a shift toward greater use of distal polyadenylation sites when the fibroblasts entered quiescence. We observed significant overlap between the genes that shift to greater distal site use with quiescence and CstF-64 or CPSF73 knockdown. Conclusions: The shift to greater distal site use with quiescence may reflect in part the reduced levels of cleavage and polyadenylation factors. Overall design: Perform polyadenylation site-enriched RNA-Seq on: (1) two biological replicates of proliferating and quiescent (contact-inhibited) cells, and (2) two biological replicates of control and polyadenylation factor (CstF64, CPSF73 or CFIm25) knockdown cells.

Description
Purpose: Information processing in the brain relies on precise patterns of synapses between neurons. The molecular mechanisms by which this specificity is achieved remains elusive. In the medulla of the Drosophila visual system, different neurons form synaptic connections in different layers. Methods: we developed methods to purify seven neuronal cell types (R7, R8 and L1-L5 neurons) using Fluorescence Activated Cell Sorting. Results: we show that neurons with different synaptic specificities express unique combinations of mRNAs encoding hundreds of cell surface and secreted proteins. Using RNA sequencing and MiMIC-based protein tagging, we demonstrate that 21 paralogs of the Dpr family, a subclass of Immunoglobulin (Ig)-domain containing proteins, are expressed in unique combinations in homologous neurons with different layer-specific synaptic connections. Dpr interacting proteins (DIPs), comprising nine paralogs of another subclass of Ig superfamily proteins, are expressed in a complementary layer-specific fashion in a subset of synaptic partners. We propose that pairs of Dpr/DIP paralogs contribute to layer-specific patterns of synaptic connectivity. Conclusions: This complexity is mirrored by the complexity of the cell surface and secreted molecules expressed by each of the R cell and lamina neurons profiled in this study. How this complexity contributes to specificity remains elusive, but the convergence of improved histological, genetic and molecular tools promises to provide important insights into the molecular recognition strategies controlling synaptic specificity. Overall design: We chose 7 time points for RNA-seq analysis of R cells during pupal development corresponding to 24, 35, 40, 45, 53, 65 and 96 hrs after pupal formation (APF).

Description
Background: Although chamber specialization is critical for proper cardiac function, a comprehensive, genome-wide analysis of the cardiac transcriptome, including identification of regional differences in mRNA and lncRNA expression patterns for the four chambers and interventricular septum of the non-failing human heart, has not been performed. Methods and Results: mRNA and long noncoding RNA (lncRNA) transcriptional profiling of the left (LA) and right (RA) atria, left (LV) and right (RV) ventricles, and the interventricular septum (IVS) of non-failing human hearts (N=8) was performed by deep sequencing. Analysis of the mRNA and lncRNA expression profiles revealed that the different regions of the heart are distinct. Differential expression analysis of paired tissue samples identified 5,747 mRNAs and 2,794 lncRNAs with chamber-enriched expression patterns. The largest differences in mRNA and lncRNA expression were evident between atria and ventricular samples, including regional differences in ~20% of all cardiac expressed mRNA and lncRNA transcripts. Regional differences in mRNA and lncRNA expression were also evident, although to a lesser extent, between the LA and RA, and between the LV, RV and IVS. Gene ontology classification of differentially expressed gene sets revealed regional differences in chamber specialization, including differences in signaling, metabolism, and muscle contraction. Sex differences in mRNA and lncRNA gene expression profiles were also identified between male and female LA and RA samples. Conclusions: There are marked regional differences in the mRNA and lncRNA expression profiles in non-failing adult human heart, and are associated with chamber specialization. Overall design: 8 human hearts, 5 chambers from each

Description
Our strategy was to manipulate mTOR signaling in vivo, then characterize the transcriptome and translating mRNA in liver tissue. In adult rats, we used the non-proliferative growth model of refeeding after a period of fasting, and the proliferative model of liver regeneration following partial hepatectomy. We also studied livers from pre-term fetal rats (embryonic day 19-20) in which fetal hepatocytes are asynchronously proliferating. All three models employed rapamycin to inhibit mTOR signaling.

Description
Follicular lymphoma (FL) is an indolent lymphoma associated with follicular center B cells, and typically contains the Bcl-2 chromosomal translocation t(14;18), which leads to overexpression of the anti-apoptotic intracellular protein Bcl-2. FLs are sensitive to chemotherapy; however, patient relapses occur and response duration becomes progressively shorter, with the majority of patients eventually dying from the disease. Enzastaurin (LY317615), an acyclic bisindolylmaleimide, was initially developed as an ATP-competitive selective inhibitor of PKC. We found, in agreement with recent reports, that enzastaurin inhibits cell proliferation and induces apoptosis. These results are consistent with decreased phosphorylation of the Akt pathway and its downstream targets. To provide new insights into the anti-tumor action of enzastaurin on non-Hodgkin lymphoma, we investigated its effects on gene expression profiles of the B cell lymphoma RL cell line by oligonucleotide microarray analysis. We identified a set of 41 differentially expressed genes, mainly involved in cellular adhesion, apoptosis, inflammation, and immune and defense responses. These observations provide new insights into the mechanisms involved in the induction of apoptosis by enzastaurin in B cell lymphoma cell lines, and identify possible pathways that may contribute to the induction of apoptosis.
