BACKGROUND: Excessive production and/or reduced excretion of uric acid could lead to hyperuricemia, which could be a major cause of disability. Hyperuricemia has received increasing attention in the last few decades due to its global prevalence. Cichorium intybus L., commonly known as chicory, is a perennial herb of the asteraceae family. It was previously shown to exert potent hypouricemic effects linked with decreasing uric acid formation in the liver by down-regulating the activity of xanthine oxidase, and increasing uric acid excretion by up-regulating the renal OAT3 mRNA expression...

Cichorium intybus L. (Asteraceae family) is a world-wide grown plant known as chicory. In traditional medicine, this plant is used as diuretic, anti-inflammatory, digestive, cardiotonic and liver tonic. Chromatographic purification of the supercritical fluid extract of aerial parts of C. intybus on silica gel column led to isolation of three compounds: new compound, 28β-hydroxytaraxasterol (I), and two known compounds usnic acid (II) and β-sitosterol (III). Purification of the ethanolic extract of aerial parts of this plant on silica gel column chromatography yielded four compounds: 1,3-dioleylglycerate (IV), sitoindoside II (V), 11β-13-dihydrolactucin (VI) and β-sitosterol-3-O-glucoside (VII)...

Arbuscular mycorrhizal fungi (AMF) establish beneficial mutualistic symbioses with land plants, receiving carbon in exchange for mineral nutrients absorbed by the extraradical mycelium (ERM). With the aim of obtaining in vivo produced ERM for gene expression analyses, a whole-plant bi-dimensional experimental system was devised and tested with three host plants and three fungal symbionts. In such a system, Funneliformis mosseae in symbiosis with Cichorium intybus var. foliosum, Lactuca sativa, and Medicago sativa produced ERM whose lengths ranged from 9...

Climate change causes permafrost thawing, and we are confronted with the unpredictable risk of newly discovered permafrost microbes that have disease-causing capabilities. Here, we first characterized the detailed chemical structure of the lipid A moiety from a Pseudomonas species that was isolated from thawing arctic permafrost using MALDI-based mass spectrometric approaches (i.e., MALDI-TOF MS and MALDI-QIT-TOF MS(n)). The MALDI multi-stage mass spectrometry (MS) analysis of lipid A extracted from the Pseudomonas sp...

Intensively managed grasslands are dominated by highly productive grass-clover mixtures. Increasing crop diversity by inclusion of competitive forbs may enhance biomass production and sustainable biofuel production. Here we examined if one or all of three forbs (chicory, Cichorium intybus L.; caraway, Carum carvi L.; plantain, Plantago lanceolata L.) included in ryegrass-red clover mixtures enhanced above- and below-ground productivity, and assessed their biofuel potentials, based on a three-year experiment with and without fertilisation as cattle slurry...

In Cichorium intybus, inulin metabolism is mediated by fructan-active enzymes (FAZYs): sucrose:sucrose 1-fructosyltransferase (1-SST), fructan:fructan 1-fructosyltransferase (1-FFT), and fructan 1-exohydrolases 1, 2a and 2b (1-FEH1, -2a and -2b), respectively. While these enzymes have been rigorously characterized, the transcriptional network orchestrating their development- and stress-related expression has remained largely unknown. Here, the possible role of R2R3-MYB transcription factors in FAZY regulation was explored via bioinformatic identification of R2R3-MYBs (using an RNA sequencing (RNAseq) database), studies of co-expression of these factors with target genes, in vivo transient transactivation assays of FAZY target promoters (dual luciferase assay), and a yeast one-hybrid assay investigating the specificity of the binding of these factors to cis-elements...

Belgian endive (Cichorium intybus L. var. foliosum Hegi), a popular produce in northern Europe, has been thoroughly studied in regard to its bitter sesquiterpene lactones content. Much less is known about on its sweetness and crunchiness, which are typically linked to the content of polar compounds such as sugars, organic acids and salts. Through HILIC-HPLC-MS, it was shown that simple sugars, amino acids, and potassium chloride are abundant in Belgian endive extracts. Subsequently, a HILIC-HPLC-ELSD method for the analysis of such compounds with run times below six minutes was developed...

SCOPE: Chicory (Cichorium intybus L.) is a perennial herb often consumed as a vegetable, whereas the ground and roasted roots are blended as a coffee substitute. Caffeoylquinic or chlorogenic acids (CQA), the abundant intermediates of lignin biosynthesis in chicory, have been reported to improve glucose metabolism in humans, but the functional group in their structure responsible for this effect has not been yet characterized. METHODS AND RESULTS: Here, we showed that three di-O-caffeoylquinic acids suppressed hepatic glucose production in H4IIE rat hepatoma cells by reducing expression of glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK), two key enzymes that regulate hepatic gluconeogenesis...

An off-line high performance liquid chromatography (HPLC) coupled with chemical methods has been developed to evaluate antioxidant activity of 11 standard polyphenol compounds (SPCs) and vitamin C (Vc) in terms of radical scavenging abilities. The structure-activity relationships of each SPC were also discussed. SPCs showed different abilities in scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethyl-benzthiazoline-6-sulphonate (ABTS(+)) and hydroxyl (OH) free radicals. Among SPCs, quercetin and kaempferol, as typical flavonoids, displayed the greatest radical-scavenging activities and even exhibited higher activity in OH radical removal ability than that of Vc...

The roadside habitat can be challenging for plants, which must maintain normal biological processes despite an influx of airborne pollutants. While the effects of many gases on plants have been quantified, the impacts of particulate pollutants have been relatively less studied. This is especially true of field experiments where particle dispersion may be influenced by meteorology and roadway use. We examined chicory (Cichorium intybus L.) along roadsides in the Cincinnati, Ohio metropolitan area to assess particulate influence on plant pollination through stigmatic clogging...

In chicory taproot, the inulin-type fructans serve as carbohydrate reserve. Inulin metabolism is mediated by fructan active enzymes (FAZYs): sucrose:sucrose 1-fructosyltransferase (1-SST; fructan synthesis), fructan:fructan-1-fructosyltransferase (1-FFT; fructan synthesis and degradation), and fructan 1-exohydrolases (1-FEH1/2a/2b; fructan degradation). In developing taproot, fructan synthesis is affected by source-to-sink sucrose transport and sink unloading. In the present study, expression of FAZYs, sucrose transporter and CWI isoforms, vacuolar invertase and sucrose synthase was determined in leaf blade, petiole and taproot of young chicory plants (taproot diameter: 2 cm) and compared with taproot fructan profiles for the following scenarios: (i) N-starvation, (ii) abscisic acid (ABA) treatment, (iii) ethylene treatment (via 1-aminoyclopropane-1-carboxylic acid [ACC]), and (iv) cold treatment...

Cyclophosphamide (CP) is a widely utilized chemotherapy drug. CP and its metabolite, acrolein, could induce hepatotoxicity. In this study, Cichorium glandulosum seed (CGS) effectively mitigated CP-induced hepatotoxicity in mice. Protection of cynarin, the major compound of CGS, against acrolein cytotoxicity in HepG2 cells was studied. Pretreatment with cynarin could improve cell survival against acrolein cytotoxicity. Cynarin restored the balance of glutathione (GSH) and reactive oxygen species (ROS), and inhibited mitochondrial depolarization...
