Study ID	ST001929
Study Title	Metabolomics profiles of premenopausal women are different based on O-desmethylangolensin metabotype (Part 2)
Study Summary	Urinary O-desmethylangolensin (ODMA) concentrations provide a functional gut microbiome marker of dietary isoflavone daidzein metabolism to ODMA. Individuals who do not have gut microbial environments that produce ODMA have less favorable cardiometabolic and cancer risk profiles. Urinary metabolomics profiles were evaluated in relation to ODMA metabotypes within and between individuals over time. Secondary analysis was conducted of data from the BEAN2 trial, which was a cross-over study of premenopausal women consuming six months on a high- and a low-soy diet, each separated by a 1-month washout period. In all of the 672 samples in the study, 66 of the 84 women had the same ODMA metabotype at seven or all eight time points. Two or four urine samples per woman were selected based on temporal metabotypes in order to compare within and across individuals. Metabolomics assays for primary metabolism and biogenic amines were conducted in 60 urine samples from 20 women.

Collection:

Collection ID:	CO002000
Collection Summary:	Urine biospecimens were collected during cross-over trial among premenopausal women conducted from 2007-2010, and details about the study design and population are published elsewhere (Morimoto et al 2014; Maskarinec et al 2011; Maskarinec et al 2012). The BEAN2 trial was a cross-over study with six months on a high- and a low-soy diet, each separated by a 1-month washout period. The objective of the study was to evaluate soy intake and nipple aspirate fluid, a possible indicator of breast cancer risk. Eligibility criteria for the parent study included a normal mammogram, no oral contraceptives, not pregnant, no previous cancer diagnosis or breast surgery, regular menstrual periods, low soy intake, and the ability to produce nipple aspirate fluid. There were 84 women from the original trial who had eight stored urine samples over the cross-over intervention, from which 60 samples were selected for metabolomics analysis.
Sample Type:	Urine

Treatment:

Treatment ID:	TR002019
Treatment Summary:	As part of the parent study, daidzein, equol, and ODMA concentrations were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) as detailed elsewhere (Franke et al 2009). These previously measured concentrations were used to classify metabotypes. Each urine sample was identified as being ODMA producer/non-producer and equol producer/non-producer based on a cut-off of equol/ODMA:daidzein ratio of 0.018 (36). All samples, except two samples, which were excluded from selection, had daidzein concentrations >2 nmol/mg creatinine, indicating sufficient presence of the precursor metabolite for metabolite detection.

Chromatography ID:	CH002319
Chromatography Summary:	Urine samples were analyzed by the National Institutes of Health (NIH) West Coast Metabolomics Center in the Fiehn laboratory, using established protocols and more detail on these protocols are available elsewhere (Fiehn et al 2008). To consider broad aspects of metabolism relevant to diet, primary metabolism and biogenic amines platforms were evaluated. In brief, primary metabolism metabolites were assayed using automated liner exchange-cold injection system, gas chromatography-time of flight mass spectrometry (ALEX-CIS GCTOF).

MS Comments:	fter hard ionization by electron ionization, one electron gets abstracted from the intact molecules which hence become positively charged. The standardized -70 eV ionization voltage is so high that molecules fragment into multiple product ions, which may also form rearrangements among each other. Fragments are then analyzed by time of flight mass spectrometry which is made here by the vendor Leco corporation not to obtain accurate mass information at high resolution but instead to obtain mass spectra at very high sensitivity and speed. Mass spectrometry parameters are used as follows: a Leco Pegasus IV mass spectrometer is used with unit mass resolution at 17 spectra s-1 from 80-500 Da at -70 eV ionization energy and 1800 V detector voltage with a 230°C transfer line and a 250°C ion source.
