Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
While changes in chromatin are integral to transcriptional reprogramming during cellular differentiation, it is currently unclear how chromatin modifications are targeted to specific loci. We developed a computational model on the premise that transcription factors (TFs) direct dynamic chromatin changes during cell fate decisions. When applied to a neurogenesis paradigm, this approach predicted the TF REST as a determinant of gain of Polycomb-mediated H3K27me3 in neuronal progenitor cells. We prove this prediction experimentally by showing that the absence of REST causes loss of H3K27me3 at target promoters in trans at the same cellular state. Moreover, promoter fragments containing a REST binding site are sufficient to recruit H3K27me3 in cis, while deletion of their REST site results in loss of H3K27me3. These findings illustrate that computational modeling can systematically identify TFs that regulate chromatin dynamics genome-wide. Local determination of Polycomb activity by REST exemplifies such TF based regulation of chromatin.

- Affymetrix E. coli Genome 2.0 Array (ecoli2)
Description
Avian pathogenic Escherichia coli strains frequently cause extra-intestinal infections and are responsible for significant economic losses in the poultry industry worldwide. APEC isolates are closely related to human extraintestinal pathogenic E.coli strains and may also act as pathogens for humans. In this work, three type VI secretion systems were deleted to analyze which pathogenicity characteristics would change in the mutants, compared to wild type strain (SEPT 362).
Publication Title
The type VI secretion system plays a role in type 1 fimbria expression and pathogenesis of an avian pathogenic Escherichia coli strain.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The first bona fide PTP proto-oncogene was the Src-homology 2 domain-containing phosphatase SHP2 (encoded by PTPN11), an ubiquitously expressed PTP that transduces mitogenic, pro-survival, cell fate and/or pro-migratory signals from numerous growth factor-, cytokine- and extracellular matrix receptors. In malignancies, SHP2 is hyperactivated either downstream of oncoproteins or by mutations.We provide analysis of the breast cancer cells BT474 grown as xenografts in the presence or absence of SHP2 for 30 days.
