Project description:Several different mechanisms have been proposed to explain the possible role of cranberries, cranberry juice, and cranberry extracts in inhibiting bacterial growth. In this report, we showed that Escherichia coli showed slower growth rate in response to the presence of cranberry juice in the growth media. By compareing the global transcript profiles, significant modulation of several genes of E. coli grown in LB broth with 10% cranberry juice were identified and provided identification of the potential mechanisms involved in the inhibitory effects of cranberry juice. The results presented clearly demonstrate that the inhibitory effect on bacterial growth observed in the presence of cranberry juice/extracts is primarily a result of the iron chelation capacity of PACs and direct disruption of metabolic enzymes. The results are discussed with a focus on the genes associated with iron chelation capability. Keywords: growth inhibition of cranberry juice

Project description:Plant-based foods contain bioactive compounds such as polyphenols that resist digestion and potentially benefit the host through interactions with their gut microbiome. Based on previous observations, we hypothesized thatprobiotic Lactobacillus plantarum interact with cranberry polyphenols and dietary oligosaccharides to synergistically impact its physiology. In this study, L. plantarum ATCC BAA-793 was grown on dietary oligosaccharides including cranberry xyloglucans, fructooligosaccharides, and human milk oligosaccharidesin conjunction with proanthocyanidins (PACs) extracted from cranberry. As a result, L. plantarum exhibits a differential physiological response to cranberry PACs dependent on the carbohydrate source and polyphenol fraction introduced. Of two extracts evaluated, the PAC1 fraction increased growth regardless of oligosaccharide whereas PAC2 positively modulates growth during xyloglucan metabolism. Interestingly, PAC1 enables ATCC BAA-793 to utilize fructooligosaccharides efficiently as it is unable to ferment this substrate ordinarily. Relative to glucose, oligosaccharide metabolism increases the ratio of secreted acetic acid to lactic acid. The PAC2 fraction differentially increases this ratio during cranberry xyloglucan fermentation compared with PAC1. RNA-seq transcriptomics link expression of putative polyphenol degradation genes, polyphenol degradation profiles, and physiological phenotypes.

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:The molecular basis underlying the known anti-inflammatory and anticarcinogenic properties of cranberries is incompletely understood. We investigated the microRNA (miRNA)-modulatory effects of cranberry proanthocyanidin (PAC) and two of its main gut microbial metabolites, 3,4-dihydroxyphenylacetic acid (DHPAA) and 3-(4-hydroxyphenyl)-propionic acid (HPPA), in intestinal cells at homeostasis and in inflammatory conditions. Differentiated Caco-2BBe1 cells were pre-treated with PAC, DHPAA, or HPPA then stimulated with IL-1ß or not. Total RNA was used to profile the expression of 799 miRNAs. PAC, DHPAA, and HPPA generated subsets of shared and distinct miRNA responses. At homeostasis, miRNAs affected by the metabolites, but not by PAC, targeted genes enriched in kinase, Wnt, and growth factor signaling, cell growth and proliferation, apoptosis, and specific cancer pathways. In an inflammatory environment, pre-treatment with PAC and DHPAA, but not HPPA, reversed the expression of 16 and two IL-1ß-induced miRNAs, targeting genes enriched in inflammatory and cancer pathways. These data suggest that in the absence of inflammation, PAC may be reliant on its transformation by the gut microbiota for its miRNA-modulatory effects, while in an inflammatory environment, both PAC and DHPAA counter inflammatory miRNA responses. This work provides a novel mechanism to characterize the bioactivity of cranberry and will inform cranberry utilization in nutritional strategies for the maintenance of intestinal homeostasis.

Project description:Analysis of the effect of using a fruit and vegetable juice concentrate to reduce systemic inflammation in obesity. The hypothesis tested whether the presence of polyphenols in the fruit and vegetable juice concentrate could reduce the expression of systemic inflammatory genes in the blood of Obese patients with high levels of plasma CRP (≥3.0). Results provide evidence that systemic inflammatory genes/ and or pathways may be modulated by the fruit and vegetable juice concentrate.

Project description:The influence of cranberry proanthocyanidins on the transcriptomic responses of Streptococcus mutans during biofilm formation was investigated. Treatment regimens simulating topical exposures experienced clinically (twice-daily, 60 s each) were used over saliva-coated hydroxyapatite biofilm model. Cranberry proanthocyanidins (1.5 mg/ml) in 15% ethanol was used to treat the biofilms. Four biological replicates each for the treatment and vehicle control were used for RNA extraction and microarray.

Project description:The objective of this study was to decipher the metabolism expressed by Lactobacillus delbrueckii subsp. delbrueckii CIRM-BIA865 during soy juice fermentation using transcriptomics. The whole genome was sequenced, assembled and annotated. CIRM-BIA865 was then used to ferment soy juice to produce a soy-based yogurt. Samples were analysed in kinetics during fermentation, at pH values of 6.5, 6, 5 and 4.6. RNA from CIRM-BIA865 were extracted and sequenced using paired-end Illumina. Reads were mapped using Bowtie2 on previously obtained genome of CIRM-BIA865. No mismatch were allowed. Reads mapped on CDS were counted using htseqcount.List of differentially expressed (DE) genes between two successive sampling times (determined by pH) were generated using DEseq2 with a modified t-test and a p-value adjusted by Bonferoni inferior to 0.05. Fold changes expressed how many times genes were induced along the fermentations.

Project description:Eighteen healthy female college students between 21-29 years old with a normal BMI of 18.5-25 were recruited. Each subject was provided with a list of foods that contained significant amount of procyanidins, such as cranberries, apples, grapes, blueberries, chocolate and plums. They were advised to avoid these foods during the 1-6th day and the rest of the study. On the morning of the 7th day, a first-morning baseline urine sample and blood sample were collected from all human subjects after overnight fasting. Participants were then randomly allocated into two groups (n=9) to consume cranberry juice or apple juice. Six bottles (250 ml/bottle) of juice were given to participants to drink in the morning and evening of the 7th, 8th, and 9th day. On the morning of 10th day, all subjects returned to the clinical unit to provide a first-morning urine sample after overnight fasting. The blood sample was also collected from participants 30 min later after they drank another bottle of juice in the morning. After two-weeks of wash out period, participants switched to the alternative regimen and repeated the protocol. One human subject was dropped off this study because she missed part of her appointments. Another two human subjects were removed from urine metabolomics analyses because they failed to provide required urine samples after juice drinking.The present study aimed to investigate overall metabolic changes caused by procyanidins concentrates from cranberries and apples using a global LCMS based metabolomics approach. All plasma and urine samples were stored at -80oC until analysis.
