Description
We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To establish the role of Pparg in shaping the VAT Tregs gene profile and cell dynamics, Tregs from lymph nodes and visceral adipose tissue of mice sufficient and deficient of Pparg expression in Tregs were double sorted for microarray analysis.

Description
We identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To explore the contribution of Pparg1 and 2 in the generation of the VAT Tregs-specific gene signatures, CD4+FoxP3- T cells were transduced with Foxp3+/- Pparg1 (or Pparg2), treated with Pioglitazone or vehicle, and double sorted for microarray analysis.

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
Iron is an essential nutritional element; its deficiency in the body causes nutritional problems and a decrease in iron storage that can lead to anemia. The liver not only stores iron but is an important metabolic target as well. Dietary iron deficiency is associated with changes in the metabolism of nutrients such as lipids. However, to the best of our knowledge, a global analysis detailing the consequences of iron deficiency in the body has not yet been reported. We performed a comprehensive transcriptome analysis using DNA microarray technology to reveal the effects of iron deficiency on hepatic gene expression. Four-week-old rats were fed an iron-deficient diet or a control diet for 16 days. On day 17, the rats were sacrificed under anesthesia, and their livers were dissected for DNA microarray analysis. We identified 600 up-regulated and 500 down-regulated probe sets to characterize the iron-deficient diet group. The up-regulated probe sets contained genes for enzymes that are involved in cholesterol, amino acid, and glucose metabolisms, as well as in apoptosis. The down-regulated probe sets included genes for enzymes associated with lipid metabolism. Additionally, the 16-day iron-deficient diet induced anemia. Our gene expression analysis revealed that, as a result, cholesterol biosynthesis, gluconeogenesis, and apoptosis due to endoplasmic reticulum stress were accelerated, while fatty acid biosynthesis was suppressed by dietary iron deficiency. Our analysis also showed that cholesterol metabolism, including bile acid biosynthesis, was accelerated in the initial stages of cholesterol accumulation.

Description
To elucidate the effect of the polyphenols contained in alcoholic beverages on the metabolic stress induced by ethanol consumption, four groups of mice were fed for five weeks on Lieber's diet with or without ethanol, with ethanol plus ellagic acid, and with ethanol plus trans-resveratrol. Alcoholic fatty liver was observed in the group fed the ethanol diet but not in those fed the ethanol plus polyphenol diets. Liver transcriptome analysis revealed that the addition of the polyphenols suppressed the expression of the genes related to cell stress that were up-regulated by ethanol alone. Conversely, the polyphenols up-regulated the genes involved in bile acid synthesis, unsaturated fatty acid elongation, and tetrahydrofolate synthesis that were down-regulated by ethanol alone. Because parts of these genes were known to be regulated by the constitutive androstane receptor (CAR), we performed the same experiment in the CAR-deficient mice. As a result, fatty liver was observed not only in the ethanol group but also with the ethanol plus polyphenol groups. In addition, there was no segregation of the gene expression profiles among these groups. These results provide a molecular basis for the prevention of alcohol-induced stress by the polyphenols in alcoholic beverages.
