Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Purpose: More than 90% of children with diffuse intrinsic pontine glioma (DIPG) die within 2 years of diagnosis. There is a dire need to identify therapeutic targets, however lack of patient material for research has limited progress. We evaluated a large cohort of diffuse intrinsic pontine gliomas (DIPGs) to identify recurrent genomic abnormalities and gene expression signatures underlying DIPG.
Publication Title
Genome-wide analyses identify recurrent amplifications of receptor tyrosine kinases and cell-cycle regulatory genes in diffuse intrinsic pontine glioma.

Description
We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0).

Description
We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). For these samples, at each stage the fetal placenta and maternal decidual tissues were dissected and profiled separately (See series 1).

- Affymetrix Drosophila Genome Array (drosgenome1)
Description
We have used microarrays to identify genes expressed and required for the second mitotic wave (SMW) during eye development. Eye discs expressing Spitz under the control of GMR Gal4 have no SMW as Spitz promotes G1 arrest, ectopic differentiation also occures. To control for the ectopic differentiation, Spi expressing eye antennal discs were compared to eye antennal discs expressing activated RasV12. In discs expresseding RasV12 under the control of GMRGal4 the SMW takes place normally prior to any ectopic differentiation.
Publication Title
Spitz from the retina regulates genes transcribed in the second mitotic wave, peripodial epithelium, glia and plasmatocytes of the Drosophila eye imaginal disc.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
The objectives of this investigation were to examine changes in the host transcriptional profiles during a polymicrobial periodontal pathogens Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia infection using a murine calvarial model of inflammation and bone resorption. P. gingivalis FDC 381, T. denticola ATCC 35404, and T. forsythia ATCC 43037 was injected into the subcutaneous soft tissue over the calvaria of BALB/c mice for 3 days, after which the soft tissues and calvarial bones were excised. RNA was isolated from infected soft tissues and calvarial bones and analyzed for transcript profiles using Murine GeneChip MG-MOE430A Affymetrix arrays to provide a molecular profile of the events that occur following infection of these tissues.

- Affymetrix Xenopus laevis Genome Array (xenopuslaevis)
Description
The transcription factors Mixer and Sox17beta have well characterized roles in endoderm specification during Xenopus embryogenesis. In order to more thoroughly understand the mechanisms by which these endodermal regulators act, we expressed Mixer and Sox17beta in nave ectodermal tissue and, using oligonucleotide-based microarrays, compared their genomic transcriptional profile to that of unaffected tissue. Using this novel approach, we identified 71 transcripts that are upregulated by Mixer or Sox17beta, 63 of which have previously uncharacterized roles in endoderm development. Furthermore, an in situ hybridization screen using antisense probes for several of these clones identified six targets of Mixer and/or Sox17beta that are expressed in the endoderm during gastrula stages, providing new and regional markers of the endoderm. Our results contribute further insight into the functions of Mixer and Sox17beta and bring us closer to understanding at the molecular level the pathways that regulate endoderm development.
