Project description:In this study, we investigated the effects of organic vegetable juice supplementation on modulating the microbial community, and how its consumption ameliorates blood lipid profiles in diet-induced obese mice. Here, we analyzed the effect of organic vegetable juice on the microbial community and fatty acid synthesis via animal experiments using diet-induced obese mice and continuous colon simulation system. Organic vegetable juice supplement influenced intestinal bacterial composition from phylum to genus level, including decreased Proteobacteria in the ascending colon in the phylum. At the family level, Akkermansia which are associated with obesity, were significantly augmented in the transverse colon and descending colon compared to the control juice group. In addition, treatment with organic vegetable juice affected predicted lipid metabolism function genes related to lipid synthesis. Organic vegetable juice consumption did not have a significant effect on weight loss but helped reduce epididymis fat tissue and adipocytes. Additionally, blood lipid profiles, such as triglyceride, high-density lipoprotein, and glucose, were improved in the organic vegetable juice-fed group. Expression levels of genes related to lipid synthesis, including SREBP-1, PPARγ, C/EBPα, and Fas, were significantly decreased. Analysis of antioxidant markers, including 8-OHdG and MDA, in the vegetable juice group, indicated that blood lipid profiles were improved by the antioxidant effect. These results suggest that organic vegetable juice supplementation may modulate gut microbial community and reduce the potential role of hyperlipidemia in diet-obese mice.

Project description:Phytochemicals from fruit and vegetables reduce systemic inflammation. This study examined the effects of an encapsulated fruit and vegetable (F&V) juice concentrate on systemic inflammation and other risk factors for chronic disease in overweight and obese adults. A double-blinded, parallel, randomized placebo-controlled trial was conducted in 56 adults aged ≥40 years with a body mass index (BMI) ≥28 kg/m². Before and after eight weeks daily treatment with six capsules of F&V juice concentrate or placebo, peripheral blood gene expression (microarray, quantitative polymerase chain reaction (qPCR)), plasma tumour necrosis factor (TNF)α (enzyme-linked immunosorbent assay (ELISA)), body composition (Dual-energy X-ray absorptiometry (DEXA)) and lipid profiles were assessed. Following consumption of juice concentrate, total cholesterol, low-density lipoprotein (LDL) cholesterol and plasma TNFα decreased and total lean mass increased, while there was no change in the placebo group. In subjects with high systemic inflammation at baseline (serum C-reactive protein (CRP) ≥3.0 mg/mL) who were supplemented with the F&V juice concentrate (n = 16), these effects were greater, with decreased total cholesterol, LDL cholesterol and plasma TNFα and increased total lean mass; plasma CRP was unchanged by the F&V juice concentrate following both analyses. The expression of several genes involved in lipogenesis, the nuclear factor-κB (NF-κB) and 5' adenosine monophosphate-activated protein kinase (AMPK) signalling pathways was altered, including phosphomevalonate kinase (PMVK), zinc finger AN1-type containing 5 (ZFAND5) and calcium binding protein 39 (CAB39), respectively. Therefore, F&V juice concentrate improves the metabolic profile, by reducing systemic inflammation and blood lipid profiles and, thus, may be useful in reducing the risk of obesity-induced chronic disease.

Project description:Metabolomics holds the promise to measure and quantify small molecules comprehensively in biological systems, and LC-MS (liquid chromatography coupled mass spectrometry) has become the leading technology in the field. Significant challenges still exist in the computational processing of data from LC-MS metabolomic experiments into metabolite features, including provenance and reproducibility of the current software tools. We present here, an experiment designed as serial mixtures of vegetable juice/Water and human plasma at varying ratios, nicknamed “Bloody Mary 21(BM21) to test semi-quantification at –omics scale. A subset of features are expected to have their peak areas correlated with the mixing ratio. This dataset provides an opportunity to be used as benchmark to assess the performance in quantification of processing softwares. Overall, the BM21 experiment included a serial mixture of human plasma (Qstd) and vegetable juice (or water), at the ratio of 1024:1, 256:1, 64:1, 16:1, 4:1, 1:1, 1:4, 1:16, 1:64, 1:256 and 1:1024. Along with the 11 serial mixture samples, 100% vegetable juice and 100% plasma were also included. All samples were analyzed in triplicates.

Project description:Background: The prevalence of individuals allergic to latex, exhibiting cross-hypersensitivity with plant-derived food has been frequently reported as the so-called latex-fruit syndrome. Nonetheless, molecular mechanisms underlying allergy to latex and/or fruit are poorly understood. Objective: The aims of this study were to identify candidate genes that may be associated with the pathogenesis of allergy to latex and /or vegetable food, and to assess if similar molecular pathways are involved in both types of hypersensitivity. Methods: DNA microarray analysis was performed to screen the molecular profiles of peripheral blood mononuclear cells isolated from patients with allergy to latex, to fruit, or with latex-fruit syndrome, and from control healthy subjects. Results: Gene expression profiling identified an overlapping dataset of genes commonly regulated in all the atopic patients enrolled in this study, suggesting that similar molecular mechanisms are involved in the pathogenesis of allergy to the fruit and /or latex. Several regulators of the innate and acquired immunity reported to polarize the immunological response towards a Th2-mediated immune response were overexpressed in patients. Furthermore, evidences suggested that T regulatory cell expression might be defective in allergic patients, as a consequence of a dysregulation of some inflammatory cytokines. Finally, several transcription factors that may be responsible for the Th1/Th2 imbalance were modulated in allergic patients. Conclusion and clinical implications: This study identified relevant genes that may help to elucidate the molecular mechanisms underlying allergic disease. Knowledges of critical targets, along with transcription factors regulating gene activity may facilitate the development of new therapies. Experiment Overall Design: This study aimed at the understanding of the molecular pathways involved in allergy to latex and fruit. As latex and vegetable food allergens cross-react, it could be hypothesized that similar pathways are involved in both types of hypersensitivity. Experiment Overall Design: For this purpose, patients allergic to latex (n=6), allergic to vegetable food (n=5), or suffering from latex-fruit syndrome (n=6) were enrolled from the Unit of Allergy of the Gemelli Hospital of Rome. Moreover, 4 healthy volunteers were added to this study. Five ml of blood were harvested from each individual, and PBMCs were isolated on ficoll gradient. Following sample preparation (as recommended by the manufacturer), each sample was hybridized on Affymetrix human focus array. Data were processed with Affymetrix MAS 5.0 software and averaged intensity of signals from biological replicates were calculated for further analysis. Experiment Overall Design: The CEL files for this study were lost in a computer crash.

Project description:Elevated fatty acid binding proteins (FABP) may play a role in obesity and co-morbidities. The role of nutritional interventions in modulating these levels remains unclear. The aim of this post hoc study was to determine the effect of overweight (OW) on FABP4 and FABP5 in boys in relation to indices of adiposity, insulin resistance and inflammation, and to investigate the effects of a 6-month supplementation with an encapsulated fruit and vegetable juice concentrate (FVJC) plus nutritional counselling (NC) on FABP levels. A post hoc analysis of a double-blind, randomised, placebo-controlled study of children recruited from the general paediatric population was performed. A total of thirty age-matched prepubertal boys (nine lean and twenty-one OW; aged 6-10 years) were studied. Patients received NC by a registered dietitian and were randomised to FVJC or placebo capsules for 6 months. FABP4, FABP5, glucose, insulin, homeostasis model assessment-insulin resistance (HOMA-IR), glucose-induced acute insulin response (AIR), lipid-corrected β-carotene (LCβC), adiponectin, leptin, high-sensitivity C-reactive protein (hs-CRP), IL-6 and body composition by dual-energy X-ray absorptiometry were determined before and after the intervention. FABP were higher (P < 0·01) in the OW v. lean boys and correlated directly with HOMA-IR, abdominal fat mass (AFM), hs-CRP, IL-6, and LCβC (P < 0·05 for all). FABP4 was associated with adiponectin and AIR (P < 0·05). FVJC plus NC reduced FABP4, HOMA-IR and AFM (P < 0·05 for all) but not FABP5. OW boys showed elevated FABP4 and FABP5, but only FABP4 was lowered by the FVJC supplement.
