- Illumina human-6 v2.0 expression beadchip
Description
The pathogenesis of avian influenza A H5N1 virus in human has not been clearly elucidated. There have been increasing evidence suggesting a role for virus-induced cytokine dysregulation in contributing to the pathogenesis of human H5N1 disease. However, the role of aberrant innate immune response in human lungs infected by avian influenza H5N1 virus has not been explored and direct evidence for inappropriate innate responses in lungs of avian influenza H5N1 virus infected patients is lacking.

- Illumina ratRef-12 v1.0 expression beadchip
Description
Intestinal calcium absorption is the sole pathway to supply calcium to the body and duodenum is the most efficient site of calcium absorption. Endurance exercise with moderate intensity significantly increased the intestinal calcium absorption. The unloaded non-impact excercise, such as swimming may enhance calcium absorption. However, the cellular and molecular mechanisms of this change have not been investigated. Thus, a genome-wide study by using microarray should reveal changes in the expression of several transporter genes in the intestinal absorptive cells of swimming excercised rats.
Publication Title
Endurance swimming stimulates transepithelial calcium transport and alters the expression of genes related to calcium absorption in the intestine of rats.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Background: Survival and function of insulin-secreting pancreatic -cells are markedly altered by changes in nutrient availability. In vitro, culture in 10 rather than 2mM glucose improves rodent -cell survival and function whereas glucose concentrations above 10mM are deleterious. Aim-Method: To identify the mechanisms of such -cell plasticity, we tested the effects of a 18h culture at 2, 5, 10 and 30mM glucose on the transcriptome of rat islets precultured for 1 week at 10mM glucose (Affymetrix Rat 230.2 arrays). Results: Culture in either 2-5mM or 30mM instead of 10mM glucose markedly impaired -cell function without affecting islet cell survival. Of ~16000 probe sets reliably detected in islets, ~5000 were significantly regulated at least 1.4-fold by glucose. Analysis of these probe sets with GeneCluster software identified 10 mRNA profiles with unidirectional up- or down-regulation between 2 and 10, 2 and 30, 5 and 10, 5 and 30 or 10 and 30 mM glucose, and 8 complex V-shaped or inverse V-shaped profiles with a nadir or peak level of expression in 5 or 10mM glucose. Analysis of genes belonging to these various clusters with Onto-express and GenMapp software revealed several signaling and metabolic pathways that may contribute to the induction of -cell dysfunction and apoptosis after culture in low or high vs. intermediate glucose concentration. Conclusion: We have identified 18 distinct mRNA profiles of glucose-induced changes in islet gene mRNA levels that should help understanding the mechanisms by which glucose affects -cell survival and function under states of chronic hypo- or hyperglycemia.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Myocarditis is an inflammatory disease in the heart and is mainly caused by viral infections. Viral myocarditis has been proposed to be divided into three phases; the acute viral phase, the subacute immune phase, and the chronic cardiac remodeling phase. Although individualized therapy should be applied depending on the phase, no clinical or experimental studies have found biomarkers that distinguish between the three phases of myocarditis. Theilers murine encephalomyelitis virus (TMEV) belongs to the genus Cardiovirus, and can cause myocarditis in susceptible mouse strains. Using this novel model for viral myocarditis induced with TMEV, we conducted multivariate analysis including echocardiography, serum troponin and viral RNA titration, and microarray for identifying the biomarker candidates that discriminate the three phases. Using C3H mice infected with TMEV on 4, 7, and 60 days post infection (p.i.), we conducted bioinformatics analyses, including principal component analysis (PCA) of microarray data, since our traditional cardiac and serum assays, including two-way comparison of microarray data, did not lead to the identification of a single biomarker. PCA separated heart samples clearly between the groups of 4, 7, and 60 days p.i. Representative genes contributing to the separation were as follows: 4 and 7 days p.i., innate immunity-related genes, such as Irf7, and Cxcl9; 7 and 60 days p.i., acquired immunity-related genes, such as Cd3g and H2-Aa; and cardiac remodeling-related genes, such as Mmp12 and Gpnmb. Here, sets of molecules, but not a single molecule, identified by the unsupervised PCA, were found to be useful as the phase-specific biomarkers.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Previously, we have shown that an AP-1 family member Fra-2, which is hardly expressed in normal mature T cells, is consistently over-expressed in adult T-cell leukemia/lymphoma (ATLL), and together with JunD, upregulates CCR4 and many other genes including proto-oncogenes c-Myb, MDM2, Bcl-6, and SOX4. SOX4 is frequently overexpressed in many solid tumors and considered to be a potential oncogene.
Publication Title
SOX4 is a direct target gene of FRA-2 and induces expression of HDAC8 in adult T-cell leukemia/lymphoma.

Description
Analysis of HER2-amplified NCI-N87 gastric cancer cell line exposed to 0.1 g/mL T-DM1 and subsequently cultured in the presence of gradually increasing doses, up to a maximum of 4 g/mL. The resultant cell lines that grew exponentially in the presence of T-DM1 were designated as drug resistant gastric cancer cell lines, and named N87-TDMR.
