Pro-cognitive treatments restore hippocampal proteomic and kinome alterations in Ts65Dn mice

Project description:Down syndrome is the main genetic cause of intellectual disability and is due to triplication of human chromosome 21 (HSA21). Green tea extracts containing epigallocatechin-3-gallate (green tea) improve cognition both in mouse models and individuals with Down syndrome. We here analyzed the proteome and phosphoproteome alterations in a Down syndrome mouse model, the partial trisomic Ts65Dn mice, and the effect produced by the green tea extract and environmental enrichment (EE). Trisomic hippocampi presented a dysregulated proteome, especially when looking at the phosphorylation level in cognitive-related categories (synaptic proteins, neuronal projection, neuron development, microtubule), and GTPases/kinase activity and chromatin related categories. Green tea, EE, and their phospholipids in the plasma membrane and regulates signal transduction pathways, transcription factors, DNA methylation, mitochondrial function and phosphorylation, and autophagy to exert many of its beneficial biological actions Of interest for DS, it inhibits the activity of the Dual Specificity Tyrosine-Phosphorylation-Regulated Kinase 1A (DYRK1A), a DS candidate gene located in the 21q22.2 human chromosome region4,5. Previous work from our group showed that EGCG partially rescues the effects of overexpression of a DS candidate gene, DYRK1A, on the proteome and phosphoproteome of the hippocampus of TgDyrk1A mice6. However, the extent to which these mechanisms apply to a trisomy scenario is unknown. To get insight in these mechanisms we analyzed changes in protein abundances and phosphorylation in Ts65Dn mice, and their disomic counterparts in baseline conditions and upon three treatments known to improve cognition in Ts65Dn: i) green tea extract containing EGCG, ii) environmental enrichment (EE), and iii) their combination.

Modulation of the ileal microbiota by green tea in broiler

Project description:The effects of increasing addition of green tea in dietary changes the bacterial populations in broiler ileum were evaluated. Four hundreds of AA broilers were randomly assigned to four groups with green tea addition of 0, 0.5, 1 and 2 percent in the diet. The body weight showed no difference but a digital increase positively correlated with addition of green tea. The content of green tea had a linear effect of lengthening the ileum villi. The barcoded DNA pyrosequencing method was used to reveal 15 phyla, 1157phylotypes and 3098 16S operational taxonomic units (OTUs). The most predominant bacterial phyla were Firmicutes (56.89%), Actinobacteria (30.58%), Proteobacteria (8.61%) and Bacteroidetes (2.72%). As the proportion of additional green tea increased, the abundance of phylum Actinobacteria (p=0.003) and Proteobacteria (p=0.049) almost linearly increased, while the proportion of Firmicutes (p=0.027) linearly decreased. Only 2 OTUs were significantly affected by the increased additive, Corynebacteriaceae (p=0.011) and Staphylococcaceae (p= 0.006). Triplot analysis suggested that the dominant phyla of Verrucomicrobia, TM7 and Actinobacteria were clearly related to the addition of green tea. Moreover, green tea addition influenced the construction of microbiota, and lengthened the villus in ileum by Monte Carlo permutation test. These findings provide a new understanding of the ileal microbial ecology, which may be useful in modulating the gut microbiome, and also the proper usage of powdered green tea.

Green tea polyphenols alleviate liver injury induced by di(2-ethylhexyl) phthalate in mice

Project description:Di (2-ethylhexyl) phthalate (DEHP) is a common plasticizer. Studies have revealed that DEHP exposure can cause liver damage. Green tea is one of the most popular beverages in China. Green tea polyphenols (GTPs) have been proven to have therapeutic effects on organ damage induced by heavy metal exposure. However, few study report on GTP relieving DEHP-induced liver damage.

Quantitative acetyl-proteome profiling of Camellia sinensis cv.‘Anji Baicha’ during periodic albinism reveal lysine acetylation of proteins involved in photosynthesis and secondary metabolite biosynthetic pathways

Project description:The tea plant (Camellia sinensis (L.) O. Kuntze) is often commercially used as a source of non-alcoholic beverages and is an economically important woody crop (Chen et al., 2007). As living standards have improved, the requirement for high-quality life has increased in modern society. ‘Anji Baicha’ (alias ‘Baiye 1’ or ‘White Leaf 1’) is an excellent tea cultivar with albino phenotype and it is popular in producing high-quality green tea. The traits of ‘Anji Baicha’ are as follows. Young ‘Anji Baicha’ shoots are yellow-green when the early spring temperature is below 20°C. As the leaves fully expand, the leaves become white. The leaves gradually return to green when the environmental temperature increases (Cheng et al., 1999; Li et al., 2002, 2011). Previous reports have suggested a positive correlation between amino acid concentration and albinism as well as a negative correlation between tea polyphenols and albinism (Li et al., 1996; Du et al., 2006; Xiong et al., 2013). Therefore, the quality of ‘Anji Baicha’ is much higher when new shoots become albino due to their rich amino acid content and modest tea polyphenol content. Plants adjust their metabolism in response to environmental stimuli to eventually bring about changes in protein activities and levels, and this adaptive process includes posttranslational protein modifications (PTMs) (Prabakaran et al., 2012). PTMs have been reported to regulate various processes, including DNA interaction, protein-protein interactions, enzyme activation and protein stability. Among the hundreds of different PTMs, lysine acetylation is an abundant, reversible and highly regulated PTM (Zhang et al., 2009; Wu et al., 2011).
