Detailed Description
Consumption of cranberry juice has been related to the prevention of urinary tract infection. However, due to the bitterness and astringency of cranberry products, the compliance of participants in cranberry related clinical trial is poor, which makes it difficult to further study the function of cranberry juice. Accordingly, there is a pressing need for an effective approach to verify participant compliance. In the previous study, plasma and urinary metabolome in young women following cranberry juice consumption have been investigated using a global UHPLC (Ultra high-performance liquid chromatography) -Q-Orbitrap-HRMS (High-resolution mass spectrometry) approach. PLS-DA (Partial least squares discriminant analysis) analyses showed that both plasma and urinary metabolome in young women were altered following cranberry consumption compared to baseline and apple juice consumption. Cranberry juice consumption caused a greater excretion of both exogenous and endogenous metabolites. These metabolites have been identified as candidate biomarkers for cranberry juice consumption. The established PLS-DA (Partial least squares discriminant analysis) /OPLS-DA (Orthogonal partial least squares discriminant analysis) models provide an opportunity to identify cranberry juice consumers.
It is unknown whether cranberry juice consumption influences gut microbiota profile in human. But several studies suggested that a polyphenol-rich diet improves gut microbiota profile. The previous in vitro study with human gut microbiota indicated that microbial catabolism of A-type cranberry procyanidins produced metabolites with different profiles and structures compared with those from B-type procyanidins.
Understanding microbiome change in human gut will enable the investigators to correlate and explain metabolome changes in the urine and blood, and also will explain the health benefits of cranberries.
With all the samples will be collected in this study, the metabolomics changes between short-term cranberry juice treatment (3days) and long-term treatment (21days) can be compared. Since the urinary tract protection effects of cranberry juices are often associated with chronic consumption, more metabolomic changes are expected to be identified by a long-term study.
Research Plan:
Specific aim 1: Twenty (20) healthy female college students aged 18-29 with normal BMI (Body mass index) (18.5-25) and at least 110 pounds in weight will be recruited on UF (University of Florida) campus.
Advertisement will be in the form of flyers. Contact information of investigators will be included in the flyer. Questionnaire will be used to obtain information about subjects for prescreen. All participants will be received written and oral information regarding the natural and potential risks of the study.
Participants will be advised to avoid proanthocyanidins-rich foods including cranberries, blueberries, strawberries plum, raspberries, apple, grapes, grape seed extract, pycnogenol, red wine, tea, chocolate and other cocoa products or other cranberry based supplements from the beginning of 10-day (1st-9th ) run in period to the end of the study. Participants will be suggested to consume orange, watermelon, honey dew, cantaloupe for replacement. Urine and stool sample collection kits will be distributed to all participants and participants will be trained to use the collection kits. One fecal sample will be collected by participants during any day from the 7th to 9th day. On the 10th day morning, overnight fast urine sample will be self-collected and subjects will have blood sample drawn (2 tubes, 30mL total). Breakfast will be provided for participants after fasting blood sample collection. A trained and certified phlebotomist will be hired to draw blood. After blood drawn, each participant will consume 1 bottle (250mL) of cranberry or placebo juice and another 5 bottles of cranberry or placebo juice will be given to each subject to consume in the evening of the 10th day and in the morning and evening of the 11th and12th day. One fecal sample will also be collected during the 12th- 4th day. All subjects will return to the clinical unit in the morning of the 13th day with a self-collected overnight fast urine sample and blood samples will be collected 30-60min after participants consume 1 bottle of cranberry or placebo juice. Cranberry or placebo juice will be distributed to each of the subjects to consume in the evening of the 13th day and in the morning and evening during the 14th- 29th day. Appointment will be scheduled weekly or upon the request of participants during the 14th to 29th day. One fecal sample will be collected during the 29th to 31st day. In the morning of the 30th day, overnight fast urine sample will be self-collected and subjects will have blood sample drawn after consume cranberry juice or placebo. After 14-days washout period, participants will switch to the alternative regimen and repeat the protocol. All samples collected will be aliquoted and kept in -80°C. It's unlikely to happen, but if any subject has any serious adverse effect after juice consumption, participant will be removed from the study depending on her situation for safety concern.
Preparation of urine and plasma sample collected at the13th, 48th day (3 days later after cranberry juice/placebo consumption) will follow established protocols. LC-HRMS (Liquid chromatography - High-resolution mass spectrometry) data will be normalized and imported to SIMCA (Version 13.0.3, Umetrics, Umea, Sweden) to use previously established PLS-DA (Partial least squares discriminant analysis) /OPLS-DA (Orthogonal partial least squares discriminant analysis) models to blindly identify cranberry juice consumers. Results will be sent to Ocean Spray for verification.
Specific aim 2:
The baseline fecal samples and fecal sample collected around the 30th, 65th day (21 days later after cranberry juice/placebo consumption) will be analyzed for microbiome composition. Genomic microbial DNA will be extracted from stool samples using MoBlo Power soil DNA isolation kits.. Microbiota change in the gut will be correlated with metabolome changes in the urine using redundancy and discriminant analysis. Fecal mucin and IgA (Immunoglobulin A, indicators of intestinal barrier), short chain fatty acids and ammonia in the stool samples will be analyzed using specific assay kits or HPLC (High-performance liquid chromatography) method.
Specific aim 3:
Preparation of urine and plasma sample collected at the 30th, 65th day (21 days later after cranberry juice/placebo consumption) will follow established protocols. UHPLC (Ultra high-performance liquid chromatography) -Q-Orbitrap-HRMS (High-resolution mass spectrometry) analyses, Multivariate data processing and statistical analysis will be the same as the experiment process discussed in Specific aim 2.
