Affymetrix HT Mouse Genome 430A Array (htmg430a)
Description
8 week-old male C57BL6J mice were given Gram-negative endotoxin (LPS O111:B4, 10 mg/kg) intraperitoneally at time 0. 18 hrs thereafter, they were administered 10 ml/kg 0.9% saline. Mice were sacrificed at 0, 18, or 42 hrs after LPS challenge. Kidneys were immediately collected into TRIzol for RNA preparation. Renal function was measured on blood collected at the time of tissue harvest

Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We introduced the HCMV IE1 gene into a mouse model of spontaneous glioma driven by p53KD and overexpression of Ras and PDGF and compared the transcriptomes of mouse gliomas +/- IE1. The following plasmids were utilized for glioma induction in equal parts: pT2/C-Luc/PGK-SB100, pT2/Cag-NrasV12, pT2/shP53/GFP4/mPDGF, and pT2/Cag-IE1 or pT2/C-Neo.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Mrhl is a non coding RNA identified from mouse chromosome 8. It is a 2.4kb poly adenylated, nuclear restricted RNA expressed in multiple tissues. The 2.4 kb RNA also undergoes a nuclear processing event mediated through Drosha that generates an 80nt intermediate RNA. This study was aimed at understanding the functiion of mrhl by silencing the mrhl RNA in the mouse spermatogonial cells using a pool of siRNAs targeted against the mrhl and analyse the global gene expression change using Affymetrix mouse expression array. The mRNAs that showed significant change in expression in mrhl siRNA treated cells against control were studied further for their biological significance with respect to mrhl silencing.

Description
The ability of breast cancer cells to transiently transition between epithelial and mesenchymal states is critical to complete the metastatic process. In contrast, induction of epithelial-mesenchymal transition (EMT) through the acquisition of drug persistence is a more stable event. Herein, we utilize Her2 transformed human mammary epithelial (HMLE) cells to compare a reversible model of EMT induced by TGF-beta to a stable mesenchymal phenotype induced by chronic exposure to the ErbB kinase inhibitor, lapatinib. Indeed, only a TGF-beta cells capable of returning to an epithelial phenotype resulted in long bone metastasis (BM). These four cell populations were anylzed by RNA sequencing. Overall design: The Her2 transformed HMLE cells are referred to as the parental (Par) cell line and serves as the control. These cells were treated with TGF-beta every three days for a period of 4 weeks to induce EMT (TGFB). Alternatively, the parental cells were treated with 1 micromolar of lapatinib every three days also for 4 weeks and a proliferative drug resistant population (LAPR) emerged. The TGF-beta treated cells were engrafted onto the mammary fatpad and resultant long bone metasases (BM) were isolated and subcluted ex-vivo.

Description
Purpose: The goals of this study are to determine the effect of microRNA-17 overexpression on 20,803 human genes in RASFs using Ion ProtonTM System platform. Human RASFs from two RA patients were transfected with pre-miR-17 or NC-pre-miR for 48 h and total RNA was prepared using miRNeasy kit (Qiagen). Total RNA integrity was checked using an Agilent Technologies 2100 Bio analyzer (Santa Clara, CA). 10 ng of high quality RNA was used to make cDNA for amplification with the Ion AmpliSeq Transcriptome Human Gene Expression kit (ThermoFisher Scientific). The cDNA was subjected to 12 cycles of amplification with panel primers and barcoded with adapters as recommended. Resulting sequencing libraries were quantified by qPCR using SYBR FAST master mix from KapaBiosystems (Wilmington, MA). Sets of eight libraries were balanced, pooled and sequencing beads produced on an Ion Chef. Sequencing was performed on an Ion P1 semi-conductor sequencing chip using an Ion Proton™ System (ThermoFisher Scientific, Grand Island, NY). Data was collected and primary analysis performed using Torrent Suite software version 5.0.3. Reads were mapped to the panel and expression values determined. R Software version R-3.2.3 was used to generate heatmap. Among the panel of 20,803 genes, the expression of 15,067 genes as shown in the representative heat map was observed in pre-miR-17 and NC-pre-miR transfected RASFs. A total of 664 significantly modulated genes (301 upregulated and 363 downregulated) using Student ‘t’ test were further utilized for the IPA analysis. The result of IPA predicted the protein ubiquitin pathway as a major canonical pathway affected by the differentially regulated genes. Interestingly, IPA analysis generated an interactome that showed connectivity among various ubiquitin ligases, NF-?B family, AP-1/cJun, 20S and 26S proteasome system. Conclusion: Our results clearly shows the major pathways affected by miR-17 overexpression in RASFs were Protein ubiquitination related. Overall design: mRNA profiles of pre-miR-17 and NC-pre-miR transfected RASFs were generated by AmpliSeq, in duplicate, using Ion Proton™ System.

Description
Promoter-proximal pausing of RNA polymerase II (Pol II) is a widespread transcriptional regulatory step across metazoans. Here we find that the nuclear exon junction complex (pre-EJC) is a critical and conserved regulator of this process. Depletion of pre-EJC subunits leads to a global decrease in Pol II pausing and to premature entry into elongation. This effect occurs, at least in part, via non-canonical recruitment of pre-EJC components at promoters. Failure to recruit the pre-EJC at promoters results in increased binding of the positive transcription elongation complex (P-TEFb) and in enhanced Pol II release. Notably, restoring pausing is sufficient to rescue exon skipping and the photoreceptor differentiation defect associated with depletion of pre-EJC components in vivo. We propose that the pre-EJC serves as an early transcriptional checkpoint to prevent premature entry into elongation, ensuring proper recruitment of RNA processing components that are necessary for exon definition. Overall design: polyA mRNA -seq in conditions with the indicated knockdown treatments
