Description
Plant reproduction depends on the concerted activation of many genes to assure the correct communication between pollen and pistil. Here we queried the whole transcriptome of Arabidopsis thaliana in order to identify genes with specific reproductive functions.
Publication Title

In addition to the recently published in situ transcriptomics of LCL skin lesions (Novais et al., Khouri et al.), we herein present the first systemic disease signature of localized cutaneous leishmaniasis (LCL), using Affymetrix microarrays (HuGene 1.0) followed by systems biology analysis of the PBMC transciptome of LCL patients (n=18), as compared to healthy controls (n=12).

Description
we performed RNA sequencing analysis using 10 tissue samples from human prostate and evaluated efficiency and accuracy of eRNA on mRNA-seq data analysis. Overall design: We sequenced mRNAs from the 10 human tissue samples. After that, we identified mRNAs in these samples against known human genes.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Adult BALB/c female mice were injected intraperitoneally with a single dose at 20 mg per kg of antisense oligonucleotide either against miR-29a (5-TAACCGATTTCAGATGGTGCTA-3) or against a scrambled sequence (5-TCATTGGCATGTACCATGCAGCT-3 Antisense oligonucleotides contained 2-O-methoxyethyl (2-MOE), 2-flouro (2-F) 2'-alpha-flouro units with a phosphorothioate backbone (Regulus Therapeutics). Six days following the injection, liver was isolated, total RNA was prepared as described above, and the RNA was amplified and biotinylated using the MessageAmp Premier kit (Ambion). Samples (n=4 each experimental and control) were hybridized to Affymetrix GeneChip Mouse Genome 430 2.0 Arrays in the Childrens Hospital of Philadelphia Nucleic Acids Core Facilityand analyzed with the assistance of the Penn Bioinformatics Core. Probe intensities were normalized using the GCRMA method and the significance of the log2-transformed, GCRMA-normalized signal intensities was determined using SAM

Description
Because niclosamide inhibits growth and progression of endometriotic lesions, we performed RNA-seq in order to identify genes whose expression is regulated by niclosamide in endometriotic lesions. Our results shown that niclosamide modulates several genes related to cell signaling, extracellular matrix, and inflammatory signaling. Overall design: A direct comparison of endometriotic like lesions developed in mice (n=3 per group) treated orally with either vehicle control or 200 mg/kg bw day of niclosamide for 3 weeks.

Description
The development of affinity purification technologies together with mass spectrometric analyses of the purified protein mixtures (AP-MS) has been used both to identify new protein-protein interactions and to define the subunit composition of protein complexes. Transcription factor protein interactions, however, have not been systematically analyzed using these approaches. Here, we have investigated whether ectopic expression of an affinity tagged transcription factor as bait in AP-MS experiments perturbs gene expression in cells resulting in false positive identification of bait associated proteins when typical experimental controls are used. Using quantitative proteomics and RNA-Seq, we determined that the increase in the abundance of a set of proteins caused by overexpression of the transcription factor RelA is not sufficient for these proteins to then copurify non-specifically and be misidentified as bait associated proteins. Therefore typical controls should be sufficient and a number of different baits can be compared with a common set of controls. This is of practical interest when identifying bait interactors from a large number of different baits. As expected, we found several known RelA interactors enriched in our RelA purifications (NFêB1, NFêB2, Rel, RelB, IêBá, IêBâ and IêBå). We also found several proteins not previously described in association with RelA, including the small mitochondrial chaperone Tim13. Using a variety of biochemical approaches, we further investigated the nature of the association between Tim13 and NFêB family transcription factors. The work here therefore provides a conceptual and experimental framework for analyzing transcription faction protein interactions. Overall design: Gene expression profiles were assayed in triplicate from HEK293 cells expressing either Halo-RelA, Halo-NFkB1, or Halo tag alone.

Description
This experiment analyzes the set of RNAs copurifying with the protein TNIP2 (amino acids 196-346) Overall design: HEK293 cells were transfected with constructs expressing either Halo tag (controls) or Halo-TNIP2 196-346. Total RNA was purified from an aliquot of the whole cell extract (Input samples). Halo-tagged proteins were purified from the remainder of the whole cell extract, and RNA subsequently purified from the Halo purified samples (Pulldown samples).

Description
The Saccharomyces cerevisiae R2TP protein complex consists of Rvb1, Rvb2, Pih1 and Tah1. The R2TP complex has been implicated in various cellular processes such as assembly of snoRNP complex, RNA polymerase II complex, apoptosis and PIKK signaling. The involvement of R2TP in assembling various complexes seems to be in part due to Pih1 and Tah1, which serve as adapter/recruiter proteins. Here, we have performed high resolution RNA-seq. analyses to identify differential expression levels between wild type and PIH1 and TAH1 deletion strains of Saccharomyces cerevisiae that can help in unraveling other functions of Pih1 and Tah1. Both wild type and deletion strains contained TAP (tandem affinity purification) tag at the C-terminal end of either RVB1 or RVB2. Overall design: 3 biological replicates were performed for each strains
