Study ID	ST000439
Study Title	Characterizing commonalities and differences between the breast and prostate cancer metabotypes in African-American cohorts
Study Type	Identify Breast Cancer Progression and Prostate Cancer correlative Metabolite Markers
Study Summary	Thus, we aimed to 1) understand mechanisms related to the onset and progression of BCa, 2) identify precursors and targets for prevention and therapy for each stage, grade and subtype which may contribute to the disparate impact of BCa in African American women, and 3) Identify common and different BCa metabolite markers versus PCa markers.

Sample Preparation:

Sampleprep ID:	SP000467
Sampleprep Summary:	Aliquots of each de-identified sample were shipped to the NIH RTI-RCMRC on dry ice and immediately stored at -80 °C after being logged in for metabolomics analysis. A total of 66 study samples were thawed on ice for sample preparation. A 300 uL aliquot of plasma was transferred to new labeled tubes for each study sample. Analytical quality control (QC) phenotypic pooled samples were generated by transferring a 80µL aliquot of each sample from each respective phenotypic group (Control-women, BCa-women, Control-men and PCa-men) into different 1.5 mL tubes. Phenotypic pooled samples were vortexed and 300 uL aliquots were transferred into 3 tubes/group. A total study pool was generated by transferring 250 uL of plasma from each Phenotypic pooled sample into a new 1.5 mL tube. The Total Pool sample was vortexed and 300 uL aliquots were transferred into 3 Total Pool-labeled tubes. For extraction, 900 uL of MeOH was added to all tubes, they were vortexed for 2 min on a multi-tube vortexer and centrifuged at 16,000 rcf for 5 min. A 1000 µl aliquot of the supernatant was transferred into pre-labeled 2.0mL LoBind Eppendorf tubes, and samples were lyophilized to complete dryness overnight. Samples were reconstituted with 700 uL of NMR Master Mix solution containing Chenomx ISTD: DSS-d6 and Phosphate Buffer at 7.4 pH. The tubes were vortexed for 2 min on a multi-tube vortexer and centrifuged at 16,000 rcf for 5 min. A 600uL aliquot of supernatants were transferred into a pre-labeled 5mm 4 NMR tubes for data acquisition on a 700 MHz spectrometer.
