Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Plant hormones involved in environmental stresses, namely abscisic acid (ABA), salicylic acid (SA), and jasmonic acid (JA), have been shown to interact with each other in a complex manner. To address the network of the hormone interactions, we have investigated the changes in expression under multiple hormone treatments, ABA+SA and ABA+JA. We chose cultured cells to remove the difference in the response to hormones among developmental cells or tissues. The cells were treated for 3hr and 24hr to see the rapid or transient response and steady-state response. The obtained data indicate that ABA and SA affect antagonistically, but these hormones affected many genes collaboratively. Indeed, according to the microarray data, there are many genes that responded only to ABA+SA. In addition, the ABA+SA responsive genes also responded to ABA+JA. These data suggest that hormone crosstalk is more complicated than expected and that more systematic analysis is required to untangle the hormone crosstalk network.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Arabidopsis ABA hpersensitive germination2-1 mutant shows an enhanced sensitivity to ABA. This mutant has higher levels of endogenous ABA. This mutant also exhibited SA hypersensitivity and dwarf phenotype. Regarding SA hypersensitivity, ahg2-1 exhibits higher endogenous SA level and an enhanced resistance to pathogenic bacteria. Since AHG2 encodes the Arabidopsis polyA specific ribonuclease that is involved in mRNA degradation, presumably abnormal accumulation of some mRNAs confers the unique phenotype. Transcriptome analyses are expected to offer information on the target of AHG2. In order to eliminate secondary effects of higher levels of ABA and SA, ahg2-1abi1-1 and ahg2-1sid2-2 double mutants were also examined. The transcriptome data revealed that; ahg2-1 confers unique gene expression profiles, ABA and SA affect the expression profiles of this mutant but many genes are independent of those plant hormone responses. Comparing with expression profiles of other mutants indicated that the ahg2-1 might affect mitochondrial function.

Description
Ribavirin (RBV) is a potential partner of interferon-based therapy and recently approved therapy using direct acting antivirals for patients with chronic hepatitis C, However, the precise mechanisms undelying RBV action against hepatitis C virus (HCV) replication are not yet understood. To clarify this point, we established RBV-resistant cell lines from RBV-sensitive HCV RNA-replicating cell line, OL8(3.5Y), and characterized their features.

- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Core needle biopsy (Cx) primary cancer specimens were collected at Okayama University Hospital in Japan from hormone receptor positive /HER2 negative patients that subsequently received two weeks of neoadjuvant hormone therapy. Thirty clinical TNM stage I and II women were enrolled in this study. The study was approved by the Institutional Review Board and all patients signed informed consent forms. Patients received preoperative hormone therapy daily for two weeks before surgery. Premenopausal patients received tamoxifen (40 mg) and postmenopausal patients received letrozole (2.5 mg). All patients underwent a mastectomy or breast-conserving surgery. Surgical samples after treatment were also collected. Hormone and HER2 receptor statuses were determined in the diagnostic Cx specimens before hormone therapy. Cases with 1% positive nuclear staining for estrogen receptors (ER) or progesterone receptors (PgR) with IHC were considered hormone receptor-positive. Cases with either 0 or 1 positive IHC staining for HER2 or with an HER2 gene copy number < 2.0 by fluorescent in situ hybridization (FISH) analysis were considered HER2. Specimens for gene expression analysis were collected into RNA and later stored at -80C. Gene expression profiling was performed using Affymetrix U133A gene chips. Expression data were normalized using the MAS5 algorithm, mean centered to 600, and log2 transformed before further analysis.
