Collection ID:CO002044
Collection Summary:Frozen pathologically-verified prostate tissues (PCa and adjacent benign) for metabolite were obtained from the Baylor College of Medicine Human Tissue Acquisition and Pathology Core of the Dan L. Duncan Cancer Center. All samples were collected during radical prostatectomy with informed consent and Institutional Review Board approval and stored retrospectively in a de-identified manner in the tumor bank. All tissue samples were reviewed for their tumor content by a GU pathologist prior to the metabolomics. Tissue obtained from the cancer samples contained at least 70% tumors, while benign tissues were free of tumors upon pathological examination.
Sample Type:Adipose tissue


Treatment ID:TR002063
Treatment Summary:None

Sample Preparation:

Sampleprep ID:SP002057
Sampleprep Summary:We used 50 mg of tissues for sample preparation. Lipids were extracted using a modified Bligh-Dyer method. The extraction was carried out using 2:2:2 volume ratio of water/methanol/dichloromethane at room temperature after spiking internal standards (17:0LPC, 17:0PC, 17:0PE, 17:0PG, 17:0 ceramide, 17:0SM, 17:0PS, 17:0PA, 17:0TAG, 17:0MAG, DAG 16:0/18:1, CE 17:0, and 17.0-20.4 PI). The organic layer was collected and completely dried under nitrogen. Before MS analysis, the dried extract was resuspended in 100 μL of Buffer B (10:5:85 Acetonitrile/water/Isopropyl alcohol) containing 10mM NH4OAc and subjected to LC/MS. The lipidome was separated using reverse-phase chromatography.
