- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Extracellular adenosine 5-triphosphate (ATP) is a signaling molecule. To define the global transcriptional response to ATP, we performed DNA microarray analysis using RNA derived from wild-type (Col-0) Arabidopsis and the dorn1-1 mutant, Lectin receptor kinase I.9 (At5g60300) carrying a EMS point mutation, seedlings after 100 M ATP.

Description
We report the genome-wide RNA expression levels in pluripotent mESC and as mESC differentiate towards a neuronal lineage in response to high levels of Retinoic Acid treatment in vitro. RNA-seq was performed to identify all RNAs expressed in both ESCs and neuronal cells. In total, In total, 14,443 expressed genes were detected, of which 1,834 were up-regulated and 1,477 down-regulated (fold change (FC) > -/+2.0 and p-value < 0.035) during RA-induced neuronal differentiation. The top down-regulated genes included members of the pluripotency core transcriptional network, including Klf4, Sox2, Oct4, Nanog, Suz12, Esrrb, Stat3 and Tcfcp2l1. The top up-regulated genes are important for neuronal differentiation (e.g. Pax3, Irx3, Rest and Foxd3) and reside in the RA-pathway (e.g. various homeobox genes), the retinoic acid receptors and the RA-degradation enzyme Cyp26a1. Overall design: Examination, identification and comparision of mRNA expression profliles in two cellular states.

- Affymetrix Soybean Genome Array (soybean)
Description
Soybean root hair transcriptional response to their inoculation by the symbiotic bacteria B. japonicum involved in soybean nodulation. We used the first generation of an Affymetrix microarray to quantify the abundance of the transcripts from soybean root hair cells inoculated and mock-inoculated by B. japonicum. This experiment was performed on a time-course from 6 to 48 hours after inoculation.
Publication Title

Description
To study feasibility of gene expression profiling from FFPE tissues using NuGen amplified mRNA hybridized on Affymetrix GeneChip Human Gene 1.0 ST arrays, we designed a pilot study utilizing samples from prostate cancer cohort. We selected samples from large-scale epidemiologic studies and clinical trials representative of a wide variety of fixation times, block ages and block storage conditions.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We used the flu mutant of Arabidopsis and a transgenic line that overexpresses the thylakoid-bound ascorbate peroxidase (tAPX) to address the interactions between different reactive oxygen species (ROS) signaling pathways. The conditional flu mutant of Arabidopsis accumulates excess protochlorophyllide in the dark within chloroplast membranes that upon illumination acts as a photosensitizer and generates singlet oxygen (1O2). Immediately after the release of singlet oxygen rapid changes in nuclear gene expression occur. Distinct sets of genes were activated that were different from those induced by other reactive oxygen species, superoxide or hydrogen peroxide (H2O2), suggesting that different types of active oxygen species activate distinct signaling pathways. It was not known whether the pathways operate separately or interact with each other. We have addressed this problem by modulating noninvasively the level of H2O2 in plastids by means of a transgenic line that overexpresses the thylakoid-bound ascorbate peroxidase (tAPX, line 14/2 PMID: 15165186). In the flu mutant overexpressing tAPX, the expression of most of the nuclear genes that were rapidly activated after the release of 1O2 was significantly higher in flu plants overexpressing tAPX, whereas in wild-type plants, overexpression of tAPX had only a very minor impact on nuclear gene expression. The results suggest that H2O2 antagonizes the 1O2-mediated signaling of stress responses as seen in the flu mutant. This cross-talk between H2O2- and 1O2-dependent signaling pathways might contribute to the overall stability and robustness of wild-type plants exposed to adverse environmental stress conditions.
