Project description:Whole chicory flour (Chic) and three compounds of chicory roots: fructose (Fru), chlorogenic acids (CGA) and sesquiterpene lactones (STL) were separately analyzed for their health effects in mice. A whole transcriptomic analysis was conducted using Agilent DNA microarrays to investigate their nutrigenomic effects.
Project description:We experimented on murine model and attempted to point several mechanisms by which the chicory roots acts as a functional food. To this goal, a nutrigenomic analysis was performed.
Project description:Illumina technology was used to generate mRNA profiles of stem apex of Populus yunnanensis with cutting and inverted cutting. Total RNA was extracted separately from each plant and pooled to three biological replicates per condition. RNA concentration and purity was measured using NanoDrop 2000(Thermo Fisher Scientific, Wilmington, DE). RNA integrity was assessed using the RNA Nano 6000 Assay Kit of the Agilent Bioanalyzer 2100 system (Agilent Technologies, CA, USA).
Project description:Eusocial insects have evolved the capacity to generate adults with distinct morphological, reproductive and behavioural phenotypes from the same genome. Recent studies suggest that RNA editing might enhance the diversity of gene products at the post-transcriptional level, particularly to induce functional changes in the nervous system. Using head samples from the leaf-cutting ant Acromyrmex echinatior, we compare RNA editomes across eusocial castes, identifying ca. 11,000 RNA editing sites in gynes, large workers and small workers. Those editing sites map to 800 genes functionally enriched for neurotransmission, circadian rhythm, temperature response, RNA splicing and carboxylic acid biosynthesis. Most A. echinatior editing sites are species specific, but 8M-bM-^@M-^S23% are conserved across ant subfamilies and likely to have been important for the evolution of eusociality in ants. The level of editing varies for the same site between castes, suggesting that RNA editing might be a general mechanism that shapes caste behaviour in ants. Analysis of genome-wide RNA editing in three different female castes of the the leaf-cutting ant Acromyrmex echinatior.
