Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Characterization of the underlying genetic defects in patients with a rare and peculiar phenotype is challenging. Here we have utilized whole genome expression profiling, and identified a homozygous germline mutation in the DDB2 gene in a patient with several facial tumors. The feasibility of using blood derived RNA, diminishing costs of the technology, and the limited number of samples needed provide this approach a powerful new tool that may substantially aid in such gene identification efforts.

- Affymetrix Rice Genome Array (rice)
Description
Plant hormones interact with each other and regulate gene expression to control plant growth and development. To understand the complex network, accumulation of comprehensive and integrative data of gene expression and hormone concentration is important. Using microarray, global gene expression profile was analyzed to compare with plant hormone concentration in 14 parts of rice at reproductive stage.

Description
The epiblast (foremost embryonic ectoderm) generates all three germ layers and therefore has crucial roles in the formation of all mammalian body cells. Regulation of epiblast gene expression is poorly understood due to the difficulty of manipulating epiblast tissues in vivo. In the present study, using the self-organizing properties of embryonic stem cells (ESCs), we generated and characterized epiblast-like tissue in three-dimensional (3D) culture. We identified significant genome-wide expression changes in this epiblast-like tissue. Additionally, we identified the significance of the Fgf/Erk and ectoderm formation pathways, using the bioinformatics resource IPA and DAVID. We first focused on Fgf5, which ranked in the top 10 among discovered genes. Toward functional analysis of Fgf5, we developed efficient methods of genome engineering (CRISPR/Cas9) and RNA interference (RNAi). Notably, we show one-step generation of an Fgf5 reporter line, null and in/del mutants. Furthermore, mutation types correlated well with CRISPR/Cas9 activity. For time- and dose-dependent depletion of Fgf5 over the course of development, we generated an ESC line harboring a drug-inducible short hairpin RNA cassette integrated by the Tol2 transposon system (pRNAi). Our methods provide a framework for a broad array of applications in the areas of mammalian genetics and molecular biology to understand development and to improve future therapeutics.

Description
We compared gene expression profiles between asymptomatic and symptomatic atherosclerotic plaques from the same patient. This was accomplished by analyzing carotid plaques from four patients with bilateral high-grade carotid artery stenoses one being symptomatic (TIA or stroke) and the other asymptomatic.
