Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Analysis of calli derived from the wild type (Ler), the ckh1 and ckh2 mutants cultured on media in the absence of cytokinin (control), in the presence of low (25 ng/ml kinetin) or high (200 ng/ml kinetin) levels of cytokinin, or in the presence of Trichostatin A (TSA). In these conditions, a constant 2,4-dichlorophenoxyacetic acid (2,4-D) was included as an auxin.

Description
Kurozu is a traditional Japanese rice vinegar. During fermentation and aging of the Kurozu liquid in an earthenware jar over 1 year, solid residue called Kurozu Moromi is produced. In the present study, we evaluated whether concentrated Kurozu or Kurozu Moromi could ameliorate cognitive dysfunction in the senescence accelerated P8 mouse. Senescence accelerated P8 mice were fed 0.25% (w/w) concentrated Kurozu or 0.5% (w/w) Kurozu Moromi for 4 or 25 weeks. Kurozu suppressed cognitive dysfunction and amyloid accumulation in the brain, while Kurozu Moromi showed a tendency to ameliorate cognitive dysfunction, but the effect was not significant. We hypothesize that concentrated Kurozu has an antioxidant effect, however, the level of lipid peroxidation in the brain did not differ in senescence accelerated P8 mice. DNA microarray analysis indicated that concentrated Kurozu increased HSPA1A mRNA expression, a protein that prevents protein misfolding and aggregation. The increase in HSPA1A expression by Kurozu was confirmed using quantitative real-time PCR and immunoblotting methods. Therefore, the suppression of amyloid accumulation by concentrated Kurozu may be associated with HSPA1A induction. However, concentrated Kurozu could not increase HSPA1A expression in mouse primary neurons, suggesting it may not directly affect neurons.

Description
Oral food intake maintains gastrointestinal cell turnover and impacts the morphology and function of intestinal epithelial cells. However, the underlying mechanism is not fully elucidated, especially in the large intestine. Therefore, we analyzed the colonic epithelial cell turnover in starved and re-fed mice.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
We performed the oligonucleotide microarray analysis in bipolar disorder, major depression, schizophrenia, and control subjects using postmortem prefrontal cortices provided by the Stanley Foundation Brain Collection. By comparing the gene expression profiles of similar but distinctive mental disorders, we explored the uniqueness of bipolar disorder and its similarity to other mental disorders at the molecular level. Notably, most of the altered gene expressions in each disease were not shared by one another, suggesting the molecular distinctiveness of these mental disorders. We found a tendency of downregulation of the genes encoding receptor, channels or transporters, and upregulation of the genes encoding stress response proteins or molecular chaperons in bipolar disorder. Altered expressions in bipolar disorder shared by other mental disorders mainly consisted of upregulation of the genes encoding proteins for transcription or translation. The genes identified in this study would be useful for the understanding of the pathophysiology of bipolar disorder, as well as the common pathophysiological background in major mental disorders at the molecular level.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
In human volunteers, we evaluated changes in gene expression profiles, immunological indices, and intestinal microbiota of blood cells in subjects consuming a S.reticulata extract. Thirty healthy Japanese males were split randomly into a group ingesting 240 mg/day of S.reticulata extract -containing tablets for 4 weeks and a control group ingesting placebo tablets. Ingestion of the S.reticulata extract improved T cell proliferation and other immunological indices, and changed intestinal microbiota, increasing Bifidobacterium and Lactobacillales and decreasing Clostridium bacteria. Expression levels of many immuno-relevant genes were altered. We have shown the S.reticulata extract to enhance human immune functions.

Description
Background & Aims: Recent genomic studies have identified frequent mutations of AT-rich interactive domain 2 (ARID2) in hepatocellular carcinoma (HCC), but it is not still understood how ARID2 exhibits tumor suppressor activities. Methods: We established the ARID2 knockout HCC cell lines by using CRISPR/Cas9 system, and investigated the gene expression profiles and biological functions. Results: Bioinformatic analysis indicated that UV-response genes were negatively regulated in the ARID2-KO cells, and they were certainly sensitized to UV irradiation. ARID2 depletion attenuated nucleotide excision repair (NER) of DNA damage sites introduced by exposure to UV as well as chemical compounds known as carcinogens for HCC, benzo[a]pyrene and FeCl3, since XPG could not be accumulated without ARID2. By using large-scale public data sets, we validated that ARID2 knockout could lead to similar molecular changes between in vitro and in vivo, and moreover observed a higher number of somatic mutations in the ARID2-mutated subtypes than that in the ARID2 wild-type across various types of cancers including HCC. Conclusions: We provided evidence that ARID2 knockout could contribute to disruption of NER process through inhibiting the recruitment of XPG, resulting in susceptibility to carcinogens and potential hypermutation. These findings have far-reaching implications for therapeutic targets in cancers harboring ARID2 mutations.

Development of LNA gapmers, antisense oligonucleotides used for efficient inhibition of target RNA expression, is limited by non-target mediated hepatotoxicity issues. In the present study, we investigated hepatic transcription profiles of mice receiving non-toxic and toxic LNA gapmers after a single and repeat administration.
