Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
The evaluation of mycotoxicity of type B trichothecenes using a yeast gene expression comparison analysis. The yeast BY4743 derivative PDR5 mutant was used for this study. The yeast cells were treated with trichothecene mycotoxins, and incubated at 25 degree for two hours, respectively. Total RNA was isolated with commercial kit (FastRNA Pro Red kit, Q-Biogene), and amplified RNA (aRNA) was synthesized with 3'IVT Express kit (Affymetrix). All samples were hybridized with Gene Chip (Yeast Genome 2.0 Array, Affymetrix), then each array chip was scanned by GeneChip Sanner 3000 (Affymetrix).

Description
The evaluation of zymolyase treatment using yeast gene expression comparison analysis. The yeast BY4743 strain was used for this study. Yeast cells were treated with Zymolyase (final conc. 300 U/ml), and incubated at 37 degree for ten minutes. Digestion process was not provided for control sample. Total RNA was isolated with commercial kit (FastRNA Pro Red kit, Q-Biogene), and amplified RNA (aRNA) was synthesized with 3'IVT Express kit (Affymetrix). All samples were hybridized with Gene Chip (Yeast Genome 2.0 Array, Affymetrix), then each array chip was scanned by GeneChip Sanner 3000 (Affymetrix).

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The transcription factor c-MYC intron binding protein 1 (MIBP1) binds to various genomic regulatory regions, including intron 1 of c-MYC. This factor is highly expressed in post-mitotic neurons in the fetal brain and may be involved in various biological steps, such as neurological and immunological processes. In this study, we globally characterized the transcriptional targets of MIBP1 and proteins that interact with MIBP1. Microarray hybridization followed by Gene Set Enrichment Analysis revealed that genes involved in the pathways downstream of MYC, NF-B, and TGF- were downregulated when HEK293 cells stably overexpressed MIBP1. In silico transcription factor binding site analysis of the promoter regions of these downregulated genes showed that the NF-B binding site was the most overrepresented. The upregulation of genes known to be in the NF-B pathway after the knockdown of endogenous MIBP1 in HT1080 cells supports the view that MIBP1 is a downregulator of the NF-B pathway. We also confirmed the binding of the MIBP1 to the NF-B site. By immunoprecipitation and mass spectrometry, we detected O-linked -N-acetylglucosamine (O-GlcNAc) transferase (OGT) as a prominent binding partner of MIBP1. Analyses using deletion mutants revealed that a 154-amino acid region of MIBP1 was necessary for its OGT binding and O-GlcNAcylation. A luciferase reporter assay showed that NF-B-responsive expression was repressed by MIBP1, and stronger repression by MIBP1 lacking the 154-amino acid region was observed. Our results indicate that the primary effect of MIBP1 expression is the downregulation of the NF-B pathway, and that this effect is attenuated by O-GlcNAc signaling.

Description
The capacity of the hematopoietic system to promptly respond to peripheral demands relies on adequate pools of progenitors able to transiently proliferate and differentiate in a regulated manner. However, little is known about factors that may restrain progenitor maturation to maintain their reservoirs. In addition to a profound defect in hematopoietic stem cell (HSC) self-renewal, conditional knockout mice for the Pbx1 proto-oncogene have a significant reduction in lineage-restricted progenitors, including common myeloid progenitors (CMPs) and, to a lesser extent, granulocyte-monocyte progenitors (GMPs).
