Affymetrix Plasmodium/Anopheles Genome Array (plasmodiumanopheles)
Description
P. falciparum NF54 proliferates under micro-aerophilic conditions in an environment of 3% O2, 4% CO2, 93% N2. This strain was gradually adapted to proliferate under standard tissue culture conditions of 5% CO2/95% air (~19% O2) to generate P. falciparum HOX. We compared global gene expression profiles of the two strains to identify differences, if any.

Description
Piriformospora indica, an endophytic fungus of Sebacinales, colonizes the roots of many plant species including Arabidopsis thaliana. The symbiotic interaction promotes plant per-formance, growth and resistance/tolerance against abiotic and biotic stress. We demonstrate that exudated compounds from the fungus activate stress and defense responses in the Arabidopsis roots and shoots before the two partners are in physical contact. They induce stomata closure, stimulate reactive oxygen species (ROS) production, stress-related phytohormone accumulation and activate defense and stress genes in the roots and/or shoots. Once a physical contact is established, the stomata re-open, ROS and phytohormone levels decline, and the gene expression pattern indicates a shift from defense to mutualistic interaction.
Publication Title
The interaction of Arabidopsis with Piriformospora indica shifts from initial transient stress induced by fungus-released chemical mediators to a mutualistic interaction after physical contact of the two symbionts.

Description
In a fluorescence polarization screen for MYC-MAX interaction, we have identified a novel small molecule inhibitor of MYC, KJ-Pyr-9, from a Kröhnke pyridine library. The Kd of KJ-Pyr-9 for MYC in vitro is 6.5 ± 1.0 nM as determined by backscattering interferometry; KJ-Pyr-9 also interferes with MYC-MAX complex formation in the cell as shown in a protein fragment complementation assay. KJ-Pyr-9 specifically inhibits MYC-induced oncogenic transformation in cell culture; it has no or only weak effects on the oncogenic activity of several unrelated oncoproteins. KJ-Pyr-9 preferentially interferes with the proliferation of MYC-overexpressing human and avian cells and specifically reduces the MYC-driven transcriptional signature. In vivo, KJ-Pyr-9 effectively blocks the growth of a xenotransplant of MYC-overexpressing human cancer cells. Overall design: 4 treatment groups analyzed in triplicate: no treatment(control), 20uM KJ-Pyr-9, 0.1ug/mL doxycycline and KJ-Pyr-9 in combination with doxycycline

Description
Glatiramer Acetate (GA) has provided safe and effective treatment for multiple sclerosis (MS) patients for two decades. It acts as an antigen, yet the precise mechanism of action remains to be fully elucidated, and no validated pharmacokinetic or pharmacodynamic biomarkers exist. In order to better characterize GAs biological impact, genome-wide expression studies were conducted with a human monocyte (THP-1) cell line. Consistent with previous literature, branded GA upregulated antiinflammatory markers (e.g. IL10), and modulated multiple immune-related pathways. Despite some similarities, significant differences were observed between expression profiles induced by branded GA and Probioglat, a differently-manufactured glatiramoid purported to be a generic GA.
Publication Title
Gene expression studies of a human monocyte cell line identify dissimilarities between differently manufactured glatiramoids.

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.

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.
