Transcript Analysis of E. coli ATCC 35218 suggest a Role of cranberry Juice in Inhibiting the growth of E. coli

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

Cranberry proanthocyanidins and dietary oligosaccharides synergistically modulate Lactobacillus plantarum physiology

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.

Transcriptome analysis of Streptococcus mutans biofilms in response to cranberry proanthocyanidins

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.

MicroRNA profiling in Caco-2BBe1 cells in response to cranberry proanthocyanidin or its metabolites with and without IL-1β

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.

Transcription profiling of human aortic endothelial cells treated with with oligomeric procyanidins extracts

Project description:Human aortic endothelial cells were grown in culture until confluent. In three experiments using cells derived from three separate donors confluent cultures were incubated for 6 h with contol medium, or medium containing either extracts of oligomeric procyanidins from cranberry juice or red wine, or a procyanidin-rich grape seed extract. At the end of the 6 h treatment period conditioned media samples were retained for immunoassay of secreted peptides and proteins, and RNA was extracted for microarray analysis. Experiment Overall Design: Each experiment used cells from one donor. Treatment conditions were: control medium, cranberry extract (CRE), grape seed extract (GSE), and red wine extract (RWE).

Cranberry derived proanthocyanidins induce a state of iron-limitation in uropathogenic Escherichia coli CFT073 as revealed by microarray analysis

Project description:Transcriptional profiles of uropathogenic Escherichia coli CFT073 exposed to cranberry-derived proanthocyanidins (PACs) were determined. Our results indicate that bacteria grown on media supplemented with PACs were iron-deprived. To our knowledge, this is the first time that PACs have been shown to induce a state of iron-limitation in this bacterium. Cultures of E. coli CFT073 were streaked onto LB agar plates and incubated (37°C, 24 h). A single colony was inoculated into 150 mL of LB broth. Three inoculated flasks contained LB broth alone (controls), and three inoculated flasks were supplemented with cranberry PACs (100 µg/mL). After incubation (37°C, 5 h, 200 rpm to mid-log growth phase), bacteria were harvested for RNA extraction.
