Project description:Background & Aims: Non-alcoholic fatty liver disease (NALFLD)-associated changes in gut microbiota are important drivers of disease progression toward fibrosis. Therefore, reversing microbiota alterations could ameliorate NAFLD progression. Oat beta-glucan, a non-digestible polysaccharides, has shown promising therapeutic effects on hyperlipidemia associated with NAFLD, but its impact on gut microbiota and most importantly NAFLD fibrosis remains unknown. Methods: We performed detailed metabolic phenotyping including body composition, glucose tolerance, and lipid metabolism as well as comprehensive characterization of the gut-liver axis in a western-style diet (WSD)-induced model of NAFLD and assessed the effect of a beta-glucan intervention on early and advanced liver disease. Gut microbiota was modulated using broad-spectrum antibiotic (Abx) treatment. Results: Oat beta-glucan supplementation did not affect WSD-induced body weight gain, glucose intolerance, and the metabolic phenotype remained largely unaffected. Interestingly, oat beta-glucan dampened NAFLD inflammation, associated with significantly reduced monocyte-derived macrophages (MoMFs) infiltration, fibroinflammatory gene expression, and strongly reduced fibrosis development. Mechanistically, this protective effect was not mediated by changes in bile acid composition or signaling, but was dependent on gut microbiota and was lost upon Abx treatment. Specifically, oat beta-glucan partially reversed unfavorable changes in gut microbiota, resulting in an expansion of protective taxa, including Ruminococcus, and Lactobacillus followed by reduced translocation of TLR ligands. Conclusions: Our findings identify oat beta-glucan as a highly efficacious food supplement that dampens inflammation and fibrosis development in diet-induced NAFLD. These results, along with its favorable dietary profile, suggest that it may be a cost-effective and well-tolerated approach to preventing NAFLD progression and should be assessed in clinical studies.

Project description:probiotics and prebiotics to maternal diets is related to decreased incidence of diarrhea and greater weight gain during lactation. Our objective was to determine the impact of adding whole ground oat as a prebiotic alone or in combination with postbiotic yeast culture (YC) (Saccharomyces cerevisiae) to sow gestation and lactation rations on milk composition, piglet growth, and incidence of post weaning diarrhea (PWD). Diets: control (CON), CON + yeast culture (YC) [5g/kg], CON + oat (15% inclusion rate) (Oat) or CON+ YC [5g/kg] + Oat (15%) were fed during the last 30 days of gestation and throughout lactation (18-21 days). Shotgun proteome analysis of day 4 and 7 postpartum milk samples found 36 differentially abundant proteins (P-adj <0.1) in both Oat and YC supplemented sows relative to CON. Notable was increased expression of antimicrobial proteins, lactoferrin and chitinase. IgG in milk of Oat supplemented sows was lower than YC supplemented sows (p<0.05) but had greater E. coli-antigen reactivity. Piglet weights at birth were similar. At weaning YC + Oat piglets weighed less and gained less weight (p<0.05) postweaning than CON. The incidence of PWD was lowest in the YC and Oat groups compared to CON and YC+ Oat groups. These data suggest that Oat or YC culture supplementation alters milk immune and antimicrobial associated proteins that can impact piglets but may have negative effects on piglet growth when given in combination.

Project description:Energy densification and enrichment of monounsaturated fatty acids increases oat’s nutritional value among small grain cereals. However, optimization of oat oil traits is challenging through conventional breeding. Using the biolistic method for oat’s oil improvement, here we showed that metabolic engineering is a feasible strategy in improving the oil traits of oat. In this study, two constructs containing three genes involved in lipid biosynthesis pathway (AtWRI1, AtDGAT, and SiOLEOSIN) were transformed into oat cultivar ‘Park’ to enhance the oil composition and content in oat grain and leaves. We performed RNA-sequencing in mature seeds and boot leaves of trasngenic lines. Transgene expression contributed to a global transcriptional reprogramming in oat seeds and leaves. Endogenous DGAT, WRI1, and OLEOSIN genes were up regulated while the genes involved in fatty acid biosynthesis expressed in opposite way between oat seeds and leaves. Transcriptomic studies revealed differential gene expression mainly enriched in lipid metabolism.

Project description:The impact of engineered nanomaterials intentionally or incidentally released in the environment on photosynthetic proteins remains largely unknown. Herein, we report positively charged iron oxide (Fe3O4) nanoparticles experience transformations in Arabidopsis thaliana plants in vivo that alter the formation and function of Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) protein corona, a key enzyme in the global carbon cycle. Elucidating rules of how nanoparticle properties and their transformations affect photosynthetic coronas will lead to more sustainable nanotechnology approaches for agriculture and the environment.

Project description:Several members of the Bacillus cereus group of bacteria carry lysogenic phages of the family Tectiviridae. The Bacilus cereus reference strain (ATCC 14579) harbor a linear plasmid (pBClin15) that is highly similar to the genomes of the Tectiviruses. Production of active phages has however never been reported for pBClin15 and the role of pBClin15 in B. cereus physiology has been enigmatic. We have for the first time demonstrated an effect of pBClin15 on the physiology of B. cereus ATCC 14579 whereby the wild type is more sensitive to DNA damaging antibiotics compared to a pBClin15 cured strain. The microarray experiments in this study were designed to highlight transcriptional differences between the B. cereus ATCC 14579 wild type and a plasmid cured variant that potentially could explain the impact of pBClin15 on the B. cereus physiology. Microarray experiments were carried out under non-stressful conditions (growth in logarithmic phase in LB medium) under which there were no phenotypic difference between the wild type and pBClin15 cured strain as well as under stressful conditions under which there were phenotypic differences between the two strain (growth in LB medium supplemented with 0.5M-5g norfloxacin per ml).

Project description:Upon exposure to light, plant cells quickly acquire photosynthetic competence by converting pale etioplasts into green chloroplasts. This developmental transition involves the de novo biogenesis of the thylakoid system, and requires reprogramming of metabolism and gene expression. Etioplast-to-chloroplast differentiation involves massive changes in plastid ultrastructure, but how these changes are connected to specific changes in physiology, metabolism and expression of the plastid and nuclear genomes is poorly understood. Here a new experimental system in the dicotyledonous model plant tobacco (Nicotiana tabacum) that allows us to study the leaf de-etiolation process at the systems level. We have determined the accumulation kinetics of photosynthetic complexes, pigments, lipids and soluble metabolites, and recorded the dynamic changes in plastid ultrastructure and in the nuclear and plastid transcriptomes. Our data describe the greening process at high temporal resolution, resolve distinct genetic and metabolic phases during de-etiolation, and reveal numerous candidate genes that may be involved in light-induced chloroplast development and thylakoid biogenesis.
