Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Breast cancer is a highly heterogeneous disease that is categorized into distinct tumor subtypes based on specific molecular attributes, which ultimately influence therapeutic options. Unlike ER+ and/or HER2+ cancers that are subject to specific targeted therapies, triple negative breast cancers (TNBCs) do not express these receptors, which leaves patients with limited treatment options. Thus, significant focus has been placed on identifying molecular attributes of basal-like disease that could be used to develop and/or direct novel treatment regimens. Activation of MYC signaling and inactivation of the RB-pathway are frequent events in many types of human cancers. These pathways influence many biological processes, such as cell proliferation, that contribute to the aggressiveness and therapeutic response of tumors. The current study examines the interaction of the MYC and RB pathways in mammary epithelial cell tumorigenesis.

Description
For the anucleate platelet it has been unclear how well platelet transcriptomes correlate among different donors or across different RNA profiling platforms, and what the transcriptomes relationship is with the platelet proteome. We generated RNA-seq pro-files of the long RNA transcriptomes from the platelets of 10 healthy young males (5 white and 5 black) with median age of 24.5 years, no notable clinical history, and no pre-vious history of thrombosis or bleeding. We also profiled the subjects messenger RNAs using the Affymetrix microarray gene expression system. We found that the abundance of platelet mRNA transcripts was highly correlated across the 10 individuals, inde-pendently of race and of the employed technology. Our RNA-seq data also showed that these high inter-individual correlations extend beyond mRNAs to several categories of non-coding RNAs. Pseudogenes represented a notable exception to this by exhibiting a clear difference in expression by race. Comparison of our mRNA signatures with the only publicly available quantitative platelet proteome data showed that most (87.5%) identified platelet proteins had a detectable corresponding mRNA. However, a high number of mRNAs that were present in the transcriptomes of all 10 individuals had no representa-tion in the proteome. The Spearman correlation of the relative abundances for those platelet genes that were represented by both an mRNA and a protein showed a weak (~0.3) yet statistically significant (P=5.0E-16) connection. Further analysis of the overlap-ping and non-overlapping platelet mRNAs and proteins identified gene groups corre-sponding to distinct cellular processes, a finding that provides novel insights for platelet biology.

Description
Using wild-type and Rps5 heterozygous embryonic stem cells, we isolated RNA from polyribosomal fractions in order to get insights into transcriptional and translational defects of such deletion. Overall design: Input, monosomes and polysomes extracted RNA samples from wild-type and Rps5 heterozygous clones (undifferentiated and differentiated, total number of samples = 12), were subjected to sequencing.

- Affymetrix Soybean Genome Array (soybean)
Description
According to the Canadian Food Inspection Agency and Health Canada, genetically modified crops are considered safe if they are substantially equivalent to a conventional crop in regards to agronomic, physiological and compositional characteristics. A recurring issue in safety assessment of genetically modified crops is the paucity of analytical methods to detect unintended or unexpected outcomes of genetic modification. Traditional targeted compound comparative analyses are limited in scope and capacity to detect unintended changes in chemical composition. This study explored the potential of using microarray technology to assess the substantial equivalence of gene expression profiles between genetically modified and conventional soybean cultivars. Different pre processing methods were applied to the raw expression data from the arrays, and clustering methods were used to try and differentiate the genetically modified cultivars from the conventional cultivars. Results showed that more variation existed between different strains of conventional cultivars than between conventional and genetically modified cultivars.
Publication Title
Effect of transgenes on global gene expression in soybean is within the natural range of variation of conventional cultivars.

Description
Transcription factor Stat5 is constitutively active in human prostate cancer but not in normal prostate epithelium. Stat5 activation is associated with prostate cancer lesions of high histological grades, and is present in the majority of castration-resistant recurrent human prostate cancers. The molecular mechnisms underlying constitutive activation of Stat5 in primary and recurrent human prostate cancer are currently unclear.
Publication Title
Stat5 promotes metastatic behavior of human prostate cancer cells in vitro and in vivo.

Description
Analysis of mammary glands from tet-inducible (rtTA) transgenic mice expressing cyclin D1 (Ccnd1). MMTV-rtTA transgenic mice (MMTV-Mouse Mammary Tumor Virus promoter) were cross-mated to cyclin D1 transgenic mice under the control of the tet operon. 8-week-old tetracycline-inducible cyclin D1/rtTA bi-transgenic pregnant female mice (12 days postcoitus) were treated with doxycycline through drinking water supplementation at a final concentration of 2 mg/ml. Control mice were rtTA transgenics alone and were treated in the same manner. After 7 days of doxycycline treatment, the mice were sacrificed and mammary glands taken for RNA isolation. Results provide insight into the in vivo gene expression pattern regulated by cyclin D1 through acute induction.

To gain insight into the molecular underpinnings of the post-mating response that depend on the germline, we independently assess the contribution of the female germline and the male germline on gene expression changes in head tissues of females using RNA-seq. Overall design: mRNA profiles of head tissues in virgin and mated (1 and 3 days post-mating) females that either have or are lacking a germline and females mated to males that either have or are lacking a germline. Samples were generated in triplicate and sequenced on an Illumina Genome Analyzer IIx.
