Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The aim was to identify genes associated to the down-regulation TARGET OF RAPAMYCIN (TOR) pathway in Arabidopsis. For this purpose, three independent amiR-tor lines (amiR-tor9, amiR-tor17 and amiR-tor 20) and EV lines 3 and 6 days after EST- or non-induction were used for expression profile analysis using Affymetrix microarray.

- Affymetrix Citrus Genome Array (citrus)
Description
We have used the citrus GeneChip array (GPL5731) to survey the transcription profiles of sweet orange in response to the bacterial pathogens Xanthomonas axonopodis pv. citri (Xac) and Xanthomonas axonopodis pv. aurantifolii (Xaa). Xac is the causal agent of the citrus canker disease on a wide range of citrus species, including sweet oranges (Citrus sinensis). On the other hand, Xaa is pathogenic to Mexican lime (Citrus aurantifolia) only, and in sweet orange it triggers a defense response. In order to identify the genes induced during the defense response (Xaa-responsive genes) or citrus canker development (Xac-responsive genes), we conducted microarrays hybridization experiments at 6 and 48 hours after bacterial infiltration (habi). The analysis revealed that genes commonly modulated by Xac and Xaa are associated with basal defenses normally triggered by pathogen-associated molecular patterns, including those involved in reactive oxygen species production and lignification. Significantly, Xac-infected leaves showed considerable changes in the transcriptional profiles of defense-, cell wall-, vesicle trafficking- and cell growth-related genes between 6 and 48 habi. This is consistent with the notion that Xac suppresses host defenses near the beginning of the infection and simultaneously changes the physiological status of the host to promote cell enlargement and division. Finally, Xaa triggered a MAP kinase signaling pathway involving WRKY and ethylene-responsive transcriptional factors known to activate downstream defense genes.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The functional activity of TRPM7 is essential for cell viability and growth, and its expression is up-regulated in certain pathological conditions. In order to assess the effects of TRPM7 activity on cellular gene expression, inducible HEK293 cell-lines harboring the wild-type mouse TRPM7 and a mutant lacking the kinase domain were established.

Description
VAAM stands for an amino acid mixture simulating the composition of Vespa, a hornet larval saliva. We conducted a comparative study on metabolism-regulatory roles of VAAM, casein-simulating amino acid mixture (CAAM), and pure water on murine hepatic and adipose tissue transcriptomes. Mice were orally fed VAAM solution ( 0.675 g/ kg BW = 2% of food-derived amino acids = 0.38% of total food energy/ day), CAAM solution ( 0.675 g / kg BW/ day) or water under ad libitum for five days. Hepatic transcriptome comparison of VAAM, CAAM and water-treated groups revealed a VAAM-specific regulation of the metabolic pathway, i.e., the down-regulation of glycolysis and fatty acid oxidation, and up-regulation of poly unsaturated fatty acid synthesis and glycogenic amino acids utilization in TCA cycle. Similar transcriptomic analysis of white and brown adipose tissues (WAT and BAT) suggested the up-regulation of phospholipid synthesis in WAT and the negative regulation of cellular processes in BAT. Because these coordinated regulations of tissue transcriptomes implicated the presence of upstream signaling common to these tissues, we conducted Ingenuity Pathways Analysis of these transcriptomes with the results that estrogenic and glucagon signals seemed to be activated in liver and WAT as well as beta-adrenergic signaling did in the three tissues by administration of VAAM. Our data provide a clue to understanding the role of VAAM in metabolic regulation of multiple tissues.

Description
To elucidate the effect of the polyphenols contained in alcoholic beverages on the metabolic stress induced by ethanol consumption, four groups of mice were fed for five weeks on Lieber's diet with or without ethanol, with ethanol plus ellagic acid, and with ethanol plus trans-resveratrol. Alcoholic fatty liver was observed in the group fed the ethanol diet but not in those fed the ethanol plus polyphenol diets. Liver transcriptome analysis revealed that the addition of the polyphenols suppressed the expression of the genes related to cell stress that were up-regulated by ethanol alone. Conversely, the polyphenols up-regulated the genes involved in bile acid synthesis, unsaturated fatty acid elongation, and tetrahydrofolate synthesis that were down-regulated by ethanol alone. Because parts of these genes were known to be regulated by the constitutive androstane receptor (CAR), we performed the same experiment in the CAR-deficient mice. As a result, fatty liver was observed not only in the ethanol group but also with the ethanol plus polyphenol groups. In addition, there was no segregation of the gene expression profiles among these groups. These results provide a molecular basis for the prevention of alcohol-induced stress by the polyphenols in alcoholic beverages.
