Project description:Microbial fermentation is involved in the processing of a dark tea popular for centuries in Northwest China which has shown many health benefits. This study will examine anti-obesity, hyperlipidemic and hyperglycemic effects of CGMCC No.8730 Eurotium cristatum (EC) fermented dark tea (8730DT).
Project description:Acute graft versus host disease is a serious condition caused by allo-reactive donor CD4+ T cells from allogenic hematopoietic stem cell transplantation. To understand the developmental relationships between T-helper states in mesenteric lymph nodes (mLN), TCR transgenic CD4+ T cells specific for a single allo-peptide (TEa cells) from mice were recovered at Days 0, 1, 2, 3, and 4 from mLN, and Day 5 from the gut and underwent processing to generate scRNA-seq dataset. TEa cells were also recovered at Day 5 from mLN and were either treated with and without IEL-isolation pre-digestion buffer as controls.
Project description:Keemun black tea is a fully fermented tea. These LC-MS data help us know the chemical diversity during processing of Keemun black tea.
Project description:BACKGROUND: Evaluation of the airway transcriptome may reveal patterns of gene expression that are associated with clinical phenotypes of asthma. To define transcriptomic endotypes of asthma (TEA) we analyzed gene expression in induced sputum that correlate with phenotypes of disease. METHODS: Gene expression was measured in sputum of subjects with asthma using Affymetrix HuGene ST 1.0 microarrays. Unsupervised clustering analysis of genes in pathways selected from the Kyoto Encyclopedia of Genes and Genomes (KEGG) identified TEA clusters. Clinical characteristics were compared and logistic regression analysis of matched blood samples defined an expression profile to determine the TEA cluster assignment in a cohort of children with asthma for validation. RESULTS: Three TEA clusters were identified. TEA cluster 1 had the most subjects with a history of intubation (P = 0.05), a lower pre-bronchodilator FEV1 (P = 0.006), a higher bronchodilator response (P = 0.03), and higher exhaled nitric oxide levels (P = 0.04), compared to the other TEA clusters. TEA cluster 2, the smallest cluster had the most subjects that were hospitalized for asthma (P = 0.04). Subjects in TEA cluster 3, the largest cluster, had normal lung function, low exhaled nitric oxide levels, and lower inhaled steroid requirements. Evaluation of TEA clusters in children confirmed that TEA clusters 1 and 2 are associated with a history of intubation (P = 5.58 x 10-06) and hospitalization (P = 0.01), respectively. CONCLUSIONS: Patterns of gene expression in the sputum and blood reveal TEA clusters that are associated with severe asthma phenotypes in children and adults. Gene expression was measured in sputum of subjects with asthma using Affymetrix HuGene ST 1.0 microarrays. Unsupervised clustering analysis of genes in pathways selected from the Kyoto Encyclopedia of Genes and Genomes (KEGG) identified TEA clusters. Clinical characteristics were compared and logistic regression analysis of matched blood samples defined an expression profile to determine the TEA cluster assignment in a cohort of children with asthma for validation.
Project description:<p>Wolfberry (Lycium.) tea has a long history of consumption in China and is an important cash crop. Wolfberry tea can be made through five processes: picking, withering, fixation, stir-firing and extracting fragrance, which will correspond to the FWB, WWS, FWS, SFWS and EFWS groups, respectively. There remains a lack of in-depth research on the analysis of the overall metabolism and changes in metabolic pathways of Wolfberry (Lycium.) tea at different processing stages. Thus, in this study, the dynamic changes of metabolites in wolfberry (Lycium.) tea during processing were investigated through metabolomic. The analysis of variability showed that the high temperature treatment in the frying procedure was the main reason for the differences between the groups. Compared with FWB, the metabolites that were up-regulated at different processing stages of wolfberry buds were mainly flavonoids, while the down-regulated metabolites were mainly lipids and amino acids and their derivatives. The volcano plots showed that the groups of SFWS and EFWS had the most significant differences of metabolites. Compared with FWB, the down-regulated amino acids and the derivatives were gradually increased as the processing, and that in the EFWS stage was up to 16. The hydrolysis of glycosides can produce monosaccharides, and the up-regulation of glycosides contributes to the formation of flavor of Wolfberry tea. This study is the first to investigate the changes of metabolic components in the production process of wolfberry tea, which will provide valuable data support for the further development of wolfberry tea in the future. In conclusion, at the different stages of Wolfberry tea making process, the metabolites of wolfberry tea could change obviously. Our research on the metabolites of Wolfberry tea is conducive to optimizing the tea making process of Wolfberry tea, improving the quality and yield of wolfberry tea, in order to meet the requirements of more Chinese and foreign consumers.</p>
Project description:For developing the more SNPs and new high-density genetic linkage map of tea plant, two parents and their 326 progenies and 147 registered tea cultivars was sequencing by newly developed Affymetrix Axiom genotyping technology
Project description:Green tea catechins are known as antioxidants beneficial to human health, but they are also defensive compounds produced by tea plants to protect them from herbivores. However, some herbivores can cope with green tea catechins and parasitize tea plants. We investigated the adaptation mechanisms of the spider mite Tetranychus kanzawai, an important arthropod pest of tea plants, to the defensive functions of green tea catechins. The degree of adaptation of spider mites to tea plants was correlated with the intra- and interspecific differences in their behavioral and xenobiotic responses to green tea catechins.
Project description:Hawk tea (Litsea coreana var. lanuginose) is a traditional Chinese tea, widely cultivated and consumed in southwestern China. It has been widely used to treat gastrosis, hepatitis, and inflammatory diseases for hundreds of years. Modern pharmacological studies demonstrate that hawk tea has protective effects against liver fibrosis, hypercholesterolemia, hyperglycemia, and inflammatory diseases . However, the molecular mechanism of hawk tea against hypercholesterolemia remains unclear. The aims of this study were to investigate the mechanisms of hawk tea extract (HTE) to lower cholesterol. Therefore, we performed genome-wide transcriptional analysis of hawk tea extracts treated HepG2 cells. Hawk tea extracts (HTE) induced significant gene modulation on HepG2 cells.
