Description
The aim of this study was to examine the role of indigenous lactobacilli in the physiological development of the stomach in mice using microarray analysis. In lactobacilli-associated gnotobiotic mice, an increased expression of the genes related to the muscle system development, such as nebulin and troponin, was observed. On the other hand, the expression of the gastrin gene dramatically decreased. A microarray analysis of the stomachs infected with H. pylori also showed both the up-regulation of muscle cell genes and the down-regulation of gastrin genes.

Description
Protein malnutrition promotes hepatic steatosis, decreases insulin-like growth factor (IGF)-I production, and retards growth. In order to identify new molecules involved in such changes, we conducted DNA microarray analysis for liver samples of rats fed isoenergetic low protein diet for 8 hours, and identified fibroblast growth factor 21 (Fgf21) as one of the most strongly up-regulated genes under conditions of acute protein malnutrition (P<0.05, FDR<0.001). In addition, amino acid deprivation from the culture media increased Fgf21 mRNA levels in rat liver-derived RL-34 cells (P<0.01). Thus, it was suggested that amino acid limitation directly increases Fgf21 expression.

Description
The purpose of this study was to establish a new prognostic model for stage II/III colon cancer. Using public DNA microarray data of colon cancer patients, we created an integrated prognostic model for classifying the patients into high- and low-risk groups based on the expression levels of 55 genes and the KRAS mutation status.

Description
Epigenetic changes accompany tumorigenesis and are required for tumor maintenance. Modulation of DNA methylation state, histone acetylation, and histone methylation, as well as reversal of disease-associated epigenetic state aberrations, can be disruptive to malignant disease progression. We produced lipophilic prodrugs of decitabine, which is a DNA methyltransferase inhibitor and is efficacious in treatment of myelodysplastic syndromes when dosed subcutaneously. Comparison of parent and prodrug activities in vitro and in vivo revealed comparable effects and unveiled several novel features of nucleoside analog molecular activity in vitro.

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
Hydrolyzed wheat proteins (HWPs) contained in cosmetics have occasionally caused immediate-type hypersensitivity following repeated skin exposure. Although the Cosmetic Ingredient Review Expert Panel concluded that <3,500 Da HWP is safe for use in cosmetics, it remains biologically unknown how allergenic HWPs evoke immediate-type allergy percutaneously. Keratinocyte-derived thymic stromal lymphopoietin (TSLP) induces type 2 immune responses, which play an essential role in the pathogenesis of immediate-type allergy. Previously, we demonstrated that protein allergens in cultured human keratinocytes strongly induced long-form TSLP (loTSLP) transcription. However loTSLP-regulating signaling by HWP is poorly understood.

We enriched for prostate cancer cells by the selection system used in human iPS purification. Gene expression signature-based chemical prediction enabled us to identify candidate drugs for reverting the EOS (early transposon promoter, OCT4 and SOX2 enhancer) signature with chemoresistance into a chemosensitive phenotype.

Description
This study was aimed at examining the effects of long-term of heat-stress on the gene expression of skeletal muscle hypertrophy. Heat- and stream-generating (HSG) sheets were placed on thigh laterally. The HSG sheets (heat-stress) were applied 8-hrs/day, once a day, 4 days/weeks, for 10 weeks. A muscle biopsy was taken from the vastus lateralis muscle (2 cm depth) of the treated leg before and after the experiment. Oligonucleotide microarray revealed that genes related to ATP-synthesis, protein synthesis and the molecular chaperonic activity were increased by heat stress. These results suggest that heat-stress might be a useful countermeasure for muscular atrophy during aging.
