Description
The tyrosine kinase ErbB2 positive breast tumors have more aggressive tumor growth, poorer clinical outcome, and more resistance to radiotherapy, chemotherapy and hormone therapy. A humanized anti-ErbB2 monoclonal antibody Herceptin and a small molecules inhibitor Lapatinib were developed and approved by FDA to treat patients with ErbB2 amplification and overexpression. Unfortunately, most ErbB2+ breast cancers do not respond to Herceptin and Lapatinib, and the majority of responders become resistant within 12 months of initial therapy (defined as secondary drug resistance). Such differences in response to Lapatinib treatment is contributed by substantial heterogeneity within ErbB2+ breast cancers. To address this possibility, we carried out transcriptomic analysis of mammary tumors from genetically diverse MMTV-ErbB2 mice. This will help us to have a better understanding of the heterogeneous response to ErbB2 targeted therapy and permit us to design better and more individualized (personalized) treatment strategies for human ErbB2 positive breast cancer.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Gene expression in eukaryotes is an essential process that includes transcription, pre-RNA processing and RNA export. All these steps are coupled and normally, any failure in one step affects the other steps and could cause nuclear mRNA retention. One important player in this interface is the poly(A)-RNA binding protein Nab2, which regulates the poly(A)-tail length of mRNAs protecting their 3-ends from a second round of polyadenylation and facilitating their nucleo-cytoplasmic export. Interestingly, here we show that Nab2 has additional roles in mRNA transcription elongation, tRNA metabolism and rRNA export.
Publication Title
Nab2 functions in the metabolism of RNA driven by polymerases II and III.

Description
Innate immune response is the first line of antiviral defense resulting, in most cases, in pathogen clearance with minimal clinical consequences. Viruses have developed diverse strategies to evade innate immune response and to ensure their survival. Using transmissible gastroenteritis virus (TGEV) as a model, we previously reported that accessory gene 7 counteracts host antiviral response by its association with the catalytic subunit of protein phosphatase 1 (PP1c). A transcriptomic analysis was performed to further investigate the effect of gene 7 absence on the host cell.

Alphacoronavirus protein 7 modulates host innate immune response.

Description
Polycomb group proteins (PcG) are well known by their function in the regulation of developmental processes. PcG mediated regulation of genetic programs required for proper development are triggered by EZH2 H3K27 methyltransferase activity. EZH1 can partially substitute EZH2 activity. However, unlike EZH2, EZH1 is presence in differentiated and adult tissues suggesting additional biological functions. Here we show that EZH2 is predominantly expressed in neural stem cells being essential for neural stem cells self renewal and homeostasis. There, it controls the transcriptional state of cell cycle regulators, such as CIP1. But it is also necessary to regulate genes involved in surveillance and neuroepithelial polarity. In contrast, EZH1 expression is more abundant in differentiated cells within the spinal cord and its downregulation unables neural stem cells to differentiate. All together our data reveal a complementary but non-redundant role of EZH2 and EZH1 in neurogenesis.
Publication Title
EZH2 regulates neuroepithelium structure and neuroblast proliferation by repressing p21.
