Project description:Soyfoods have been drawn the interrest in the roles that reducing risk of cardiovascular disease. Among various components, isoflavones have been come to the attention as beneficial soy ingredients. To evaluate the effectiveness of isoflavone content in dietary soybean (Glycine max) on modulating lipid metabolism, hepatic gene expressions involved in lipid metabolism were analyzed in rats. An isoflavone-rich cultivar (Yukipirika) and a conventional cultivar (Fukuyutaka) were employed. A principal component analysis (PCA) of microarray data was used to summarize characteristics of the experimental groups. As a result, the characteristics of the diets were largely explained by the first principal component (PC1). Soybean content in the diets distinctly separated in PC1. In contrast, isoflavone content had little effect on the mRNA expression. The GeneChip data was normalized and summarized by using SuperNORM data service (Skylight Biotech Inc.). Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data.

Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data. Male Splague-Dawley rats were randomly divided into 4 groups and fed an experimental diet for 21 days. The experimental diets were as follows: a diet containing 200 g/kg casein (Cas, n=7); a diet containing two proteins derived equally from casein and Fukuyutaka (conventional cultiver soybean) (F10, n=7); a diet containing two proteins derived from casein and Yukipirika (high-isoflavone soybean) in the proportion of three parts to one (Y05, n=7); a diet containing two proteins derived equally from casein and Yukipirika (Y10, n=8). In each of the groups, five rats with average food intake were used for microarray analysis.

Project description:For production of soy-foods or supplements, imbibition of soybean seeds in the water is required step for generation of tofu, soy-milk, and other soy-products. With an aim to get new insight into effects of different imbibition temperature (4, 25, and 55℃), this study conducted integrated proteomics and metabolomics analysis of soybean seeds. For total proteome analysis, we applied TMT labeling based quantitative proteomics combined to FASP (Filter-Aided Sample Preparation) with high-throughput LC-MS/MS. A total of 2,616 proteins were identified out of which 801 proteins showed significantly difference of protein abundance (≥1.5 fold change, Benjamini-Hochberg FDR <0.05) among 4, 25, and 55℃ imbibition seeds. Functional analysis of identified proteins showed an increased abundance of proteins functioning as glycosyl hydrolase enzymes such as beta-glucosidase, alpha and beta-galactosidase, and alpha-mannosidase, or protease, and PTMs related enzymes as well. UPLC TOF-MS analysis showed around 20 fold increase in isoflavone aglycones (daidzein and genistein) while isoflavone glycosides (daidzin and genistin) were decreased in 55℃ imbibition seed, in agreement with proteomics results which we assume positively related to increase abundance of glycosyl hydrolase. A metabolomics analysis revealed 64 metabolites were significantly altered, for example, various free amino acids showed accumulation patterns by increased abundance of various protease enzymes and further confirmed the accumulation of isoflavone aglycones and degradation of raffinose and stachyose in 55℃ imbibition seeds. Based on these results, we recommend the use of 55℃ for soybean seed imbibition to increase the quality of soy-food products.

Project description:Upon soy consumption, isoflavone metabolites attain bioactive concentrations in breast tissue possibly affecting health. Though in vitro epigenetic activity of soy metabolites has been described, the in vivo impact on the epigenome is largely unknown. Therefore, in this case-control study, the breast glandular tissue DNA methylome was explored in women undergoing an aesthetic breast reduction. After a run-in phase, 10 generally healthy Belgian or Dutch women received soymilk for 5 days. MethylCap-seq methylation profiles were compared with those of 10 matched controls. Isoflavones and their microbial metabolites were quantified in urine, serum, and glandular breast tissue (liquid chromatography-mass spectrometry) and 17β-estradiol in glandular breast tissue (immunoassay). Global DNA methylation levels were obtained for 6 cases and 5 controls using liquid chromatography-mass spectrometry. Although lower MethylCap-seq coverages were observed, mass spectrometry results and computational LINE-1 methylation analysis did not provide evidence supporting global methylation alterations upon treatment. At a false discovery rate of 0.05, no differentially methylated loci were identified. Moreover, a set of previously identified loci was specifically tested, but earlier reported results could not be validated. In conclusion, after a 5 day soymilk treatment, no epigenetic reprogramming in breast tissue could be found in this exploratory study.

Project description:Lactobacillus casei Zhang is a probiotic bacterium isolated from koumiss in Inner Mongolia of China. Gene expression dynamics of L. casei Zhang during growth in soymilk was investigated in attempt to reveal the mechanisms involved in growth stimulation for growing probiotics in. Comparison of different transcripts next to each other revealed 162 and 63 significantly induced genes in late logarithmic phase and stationary phase, of which the expression was at least 3 fold up-regulated and down-regulated, respectively. Approximately, 38.4% of the up-regulated genes were associated with amino acid transport and metabolism notably for histidine and lysine biosynthesis, followed by genes/gene clusters involved in carbohydrate transport and metabolism, lipid transport and metabolism, and inorganic ion transport and metabolism. The analysis results suggest that the stimulatory effect of soymilk-based ecosystem on the L. casei Zhang growth is more complex than amino acids or oligopeptides supply. To study gene expression dynamics of L. casei Zhang during growth in soymilk, a whole genome microarray was used to screen for differentially expressed genes when grown to lag phase, late logarithmic phase, and stationary phase.

Project description:Soybean is a rich source of protein and oil and a primary feedstock for biodiesel production. Previous research on soybean indicated that protein, oil and yield are controlled quantitatively in soybean seeds. However, genetic mechanisms controlling seed composition and yield in soybean remain unknown. We used Affymetrix Soybean GeneChips® to identify genes that are differentially expressed between developing seeds of the Minsoy and Archer soybean varieties, which differ in seed weight, yield, protein content and oil content. Some of the differentially expressed genes identified in this study may play important roles in controlling these traits.
