Project Title:Metabolic features of chronic fatigue
Project Type:Human plasma
Project Summary:More than 2 million people in the United States have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We performed targeted, broad-spectrum metabolomics to gain insights into the biology of CFS. We studied a total of 84 subjects using these methods. Forty-five subjects (n = 22 men and 23 women) met diagnostic criteria for ME/CFS by Institute of Medicine, Canadian, and Fukuda criteria. We targeted 612 metabolites in plasma from 63 biochemical pathways by hydrophilic interaction liquid chromatography, electrospray ionization, and tandem mass spectrometry in a single-injection method. Our data show that despite the heterogeneity of factors leading to CFS, the cellular metabolic response in patients was homogeneous, statistically robust, and chemically similar to the evolutionarily conserved persistence response to environmental stress known as dauer.

Sample Preparation:

Sampleprep ID:SP000478
Sampleprep Summary:None
Extraction Method:Typically, 90 μl of plasma was thawed on ice and mixed with 5 μl of isotope standards and incubated for 10 min at 20°C to permit small molecules and vitamins in the internal standards to associate with plasma binding proteins. Macromolecules (protein, DNA, RNA, glycans, etc.) were precipitated by extraction with 4 volumes (400 μl) of cold (-20°C), acetonitrile:methanol (50:50) and incubated on crushed ice for 10 min, then removed by centrifugation at 16,000g x 10 min at 4°C. The supernatants containing the extracted metabolites and internal standards were transferred to labeled cryotubes and stored at -80°C for LCMS/MS analysis.
Extract Storage:-80°C
Sample Derivatization:No
Sample Spiking:25-35 commercial stable isotope internal standards, and 57 stable isotope internal standards that were custom-synthesized in E. coli and S. cerevisiae by metabolic labeling with 13C-glucose and 13C bicarbonate
