Affymetrix Yeast Genome S98 Array (ygs98)
Description
Goal was to identify yeast genes whose expression changed as a function of the shift from growth in bulk culture to growth in an air-liquid interfacial biofilm.

Description
In this study, we explored the transcriptomic consequences of strong activation of the Notch pathway in embryonic human neural stem cells and in gliomas. For this we used a forced expression of the Notch intracellular domain (NICD).

Illumina HiSeq 2500
Description
Deregulated activity of the LATS tumor suppressors has broad implications on cellular and tissue homeostasis. We examined the consequences of downregulation of either LATS1 or LATS2 in breast cancer. Consistent with their proposed tumor suppressive roles, expression of both paralogs is significantly downregulated in human breast cancer, and loss of either paralog accelerated mammary tumorigenesis in mice. However, each paralog had a distinct impact on breast cancer. Thus, LATS2 depletion in luminal B tumors resulted in metabolic rewiring, with increased glycolysis and reduced PPARg signaling. Furthermore, pharmacological activation of PPARg elicited LATS2-dependent death in luminal B-derived cells. In contrast, LATS1 depletion augmented cancer cell plasticity, skewing luminal B tumors towards increased expression of basal-like features, in association with increased resistance to hormone therapy. Hence, these two closely related paralogs play distinct roles in protection against breast cancer; tumors with reduced expression of either LATS1 or LATS2 may rewire signaling networks differently and thus respond differently to anti-cancer treatments. Overall design: RNA was isolated from Lats1-CKO and Lats2-CKO PyMT tumors (4 samples from each). For each genotype, the corresponding wt littermate controls were used (3 samples in each batch).

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.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
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
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.
