Study IDST000361
Study TitleCharacterization and Plasticity of the Metabolome in Peripheral Cells in Bipolar I Disorder
Study TypeBroad Spectrum LCMS
Study SummaryPatients with Bipolar I Disorder (BPI) and matched non-affected controls were recruited. Males and females from all races and ethnicities between the ages of 19-65 participated in the research. Skin biopsies were obtained and fibroblasts were isolated from each of these biopsies. A total of 1 x 〖10〗^7 fibroblasts cells were used for metabolomics. Cell pellets were flash frozen in liquid nitrogen and shipped on dry ice to the NIH Eastern Regional Comprehensive Metabolomic Resource Core at RTI International in North Carolina. Metabolomics will be determined using a broad spectrum metabolomics protocol by RTI

Collection ID:CO000376
Collection Summary:For extraction, 500 µL of an ice-cold solution of 0.005 mg/mL Tryptohan-d5 in 90:10 Methanol:Chloroform (v/v) was added to the tubes containing the thawed human dermal fibroblasts cell pellets. MagNA Lyser ceramic beads were added to the tubes, and a MagNA Lyser was used to beat the samples for two thirty seconds pulses at 2,000 rpm, placing the samples on cold block for 5 minutes in between pulses. Sonication for five minutes was performed to the beaten cell samples, followed by centrifugation at room temperature and at 16,000 rcf for 4 minutes. A 300 µL aliquot of each experimental cell sample homogenized supernatant was transferred to new pre-labeled 2.0 mL LoBind Eppendorf tubes and stored at -80 °C for one hour.
