Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Hepatic gene expression profiles in 2-stage carcinogenesis study were analyzed with comprehensive DNA methylation data. Combined analysis suggested that PTEN signaling and immune response such as antigen presentation was related to one side of early heapatocarcinogenesis.

Description
Several studies have successfully detected hepatocarcinogenicity in rats based on gene expression data. Here, we constructed a model for detecting non-genotoxic (NGTX) hepatocarcinogens and predicted their MOAs in rats.

Description
ICR-derived glomerulonephritis (ICGN) mice is a novel inbred strain of mice with a hereditary nephrotic syndrome. Deletion mutation of tensin 2 (Tns2), a focal adhesion molecule, has been suggested to be responsible for nephrotic syndrome in ICGN mice, however, existence of other associative factors has been suggested. To identify additional associative factors and to better understand onset mechanism of nephrotic syndrome in ICGN mice, comprehensive gene expression analysis using DNA microarray was conducted. Immune-related pathways were markedly altered in ICGN mice kidney as compared with ICR mice. Furthermore, gene expression level of complement component 1, s subcomponent (C1s), whose human homologue has been reported to associate with lupus nephritis, was markedly low in ICGN mice kidney.

Description
It is well-known that indomethacin (the cyclooxygenase 1 & 2 inhibitor) and RU486 (or mifepristone, the progesterone receptor antagonist) block follicular rupture in rats. To characterize genetic alterations in unruptured follicles, gene expression profiles in ovarian follicle were analyzed in indomethacin- and RU486-treated female Sprague-Dawley rats. Ovaries are collected at 22:00 on the proestrus day and 10:00 on the following estrus day after a single dose of indomethacin and RU486. Histopathologically, changes depicting responses to LH surge were observed in ovaries, uteri and vagina. Total RNA was extracted from pre-ovulatory follicles or unruptured follicles collected by laser microdissection and analyzed by GeneChip. Among genes showing statistically significant changes compared to control groups, following changes were considered relevant to induction of unruptured follicles. In indomethacin-treated rats, Wnt4 was down-regulated, suggesting effect on tissue integrity and steroid genesis. In RU486-treated rats, Adamts1, Adamts9, Edn2, Ednra, Lyve1, Plat, and Pparg were down-regulated. These changes suggest effects on proteolysis for extracellular matrix or surrounding tissue (Adamts1 & 9, and Plat), constriction of smooth muscle surrounding follicles (Edn2, Ednra, and Pparg), follicular fluid (Lyve1), and angiogenesis (Pparg). Down-regulation of angiogenesis related genes (Angpt2, Hmox1, and Vegfa) was observed in both treatment groups. Here, we clarify genetic alterations induced by the inhibition of cyclooxygenase or progesterone receptor.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
CD20 is a clinically validated target for Non-Hodgkins lymphomas and autoimmune diseases. Interactions of CD20 with the B cell receptor (BCR) and components of the BCR signaling cascade have been reported. In this study we show that antibodies against CD20 or activation of the BCR by specific antibodies induce very similar expression patterns of up- or down-regulated genes in NHL cell lines indicating that CD20 may play a role in BCR signaling and vice versa.

Description
We investigated the differential regulation patterns of type I anti-CD20 monoclonal antibody (mAb) rituximab and type II obinutuzumab on a transcriptional level. Using a panel of MCL cell lines, we determined the effects of obinutuzumab and rituximab as monotherapies as well as in combination on cell viability and proliferation.

Description
A novel model of drug-resistant epilepsy based on the selection of mice treated with phenytoin (PHT) in the 6 Hz seizure model was developed. It leads to the identification of subpopulations of drug-responder and non-responder mice. Transcriptional characterization of the hippocampi from these 2 sub-populations was performed and compared. No significant difference has been observed between the 2 sample groups.
