Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Recent trials with MAPK inhibitors have shown promising results in many patients with metastatic melanoma; however, nearly all responding patients experience disease relapse. We describe here how melanoma cells respond to MAPK inhibition in a phenotype-specific manner, suggesting that slow cycling invasive phenotype cells provide a treatment-resistant pool from which disease relapse may be derived. The implication is that while MAPK inhibition may successfully treat proliferating cells, another cell population needs to be addressed at the same time.

Illumina HiSeq 4000
Description
The plasma protein FHR1 induces release of inflammatory cytokines IL-1ß, IL-6, IL-18 or TNFa from blood-derived human monocytes. RNA sequencing was performed from RNA of BSA- or FHR1-treated monocytes from 4 different donors. In response to FHR1, 522 monocytic genes were upregulated (gene ontology enrichment analysis), including 35 inflammation related genes, e.g. TNF. Also, G protein-coupled receptors such as EMR2/ADGRE2 were upregulated in response to FHR1. Overall design: Blood-derived monocytes were treated with BSA or FHR1, after 4h RNA was isolated. RNA of 4 donors were combined and sequenced.

Description
Purpose: Communication between growth cones and their environment plays a central role in assembling neural circuits. We use Tandemly-Tagged Ribosome Affinity Purification (T-TRAP) of mRNA from R cells followed by RNA-seq for multiple time points during development to follow gene expression during target selection and synapse formation. Methods: We chose a ribosome trap method by modifying the N-terminus of the Drosophila ribosomal protein RpL10 with two tandemly arranged epitopes, 3X FLAG and GFP, separated by the Tobacco Etch Virus (TEV) protease site and expressed this in specific cell types using the GAL4/UAS system. cDNA libraries were prepared from mRNA associated with the affinity purified ribosomes and sequenced using an Illumina HiSeq 2000. We mapped raw reads to the D. melanogaster reference genome (release FB2013_01) with the gapped aligner Tophat. Only reads uniquely aligned were collected.Transcript expression levels were quantified using RPKM units using customized scripts written in Perl. Results: In this study, we observed massive changes in expression of cell surface proteins over short time scales (i.e. 5 fold differences in the expression of many hundreds of genes over 5 hr intervals) as R cell growth cones encounter the processes of many different neurons during their conversion from growth cones to synaptic terminals. In addition, to changes in transcripts encoding cell surface proteins, other mRNAs changed significantly as did non-coding RNAs (lincRNAs) associated with ribosomes. Although dramatic changes in transcript levels of presynaptic proteins were not observed preceding the onset of synapse formation, marked changes in the 3''-untranslated regions of these transcripts were seen. Conclusions: These studies provide a step towards merging traditional genetic and global genomic approaches to understanding cellular recognition underlying the assembly of neural circuits. 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).

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Plants can perceive the presence of pathogens at the cell surface and plant damage-derived molecules via recognition of conserved microbial molecules, named pathogen- or microbe-associated molecular patterns (PAMPs) and damage associated molecular patterns (DAMPs). Well-studied examples of PAMPs are chito-oligomers, breakdown products of fungal cell walls and insect exoskeletons. Pectin-derived oligogalacturonides (OGs) are well-characterized DAMPs. Both PAMPs nd DAMPs are capable of activating plant immunity, generating changes in gene expression that lead to increased production of defense compounds and proteins; thus, equipping the plant cell to defend itself.

- 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.
