Study Title | High Resolution GC-MS Metabolomics of Non-Human Primate Serum |
Study Type | Non-human Primate Serum |
Study Summary | Rationale: Metabolomics analyses using gas chromatography mass spectrometry (GC-MS) - based metabolomics are heavily impeded by the lack of high-resolution mass spectrometers and limited spectral libraries to complement the excellent chromatography that GC platforms offer, a challenge that is being addressed with the implementation of high resolution (HR) platforms such as GC-Orbitrap-MS. Methods: We used serum samples from a non-human primate (NHP), a baboon (Papio hamadryas), with suitable quality controls to quantify the chemical space using an advanced HR MS platform for confident metabolite identification and robust quantification to assess the suitability of the platform for routine clinical metabolomics research. In a comparative approach, we also analyzed the same serum samples using a two-dimensional gas chromatography time-of-flight mass-spectrometer (2D GC-ToF-MS) for metabolite identification and quantification following established standard protocols. Results: Overall, the 2D GC-ToF-MS and GC-Orbitrap-MS analyses enabled identification and quantification of 555 total metabolites from the NHP serum with a spectral similarity score Rsim ≥ 900 and S/R ratio of > 25. A common set of 30 metabolites with HMDB and KEGG IDs were quantified in the serum samples by both platforms where the 2D GC-ToF-MS enabled quantification of a total 384 metabolites (118 HMDB IDs) and the GC-Orbitrap-MS analysis quantification of a total 200 metabolites (47 HMDB IDs). Conclusions: Our study provides insights into the benefits and limitations of the use of a higher mass accuracy instrument for untargeted GC-MS-based metabolomics with multi-dimensional chromatography in future studies addressing clinical conditions or exposome studies. |

Collection ID: | CO001005 |
Collection Summary: | All procedures involving animals were reviewed and approved by the Texas Biomedical Research Institute’s Institutional Animal Care and Use Committee and conducted in AAALAC approved facilities. For this study, we utilized a healthy adult male olive baboon (Papio hamadryas) maintained as part of the baboon colony at the Southwest National Primate Research Center, located on the campus of the Texas Biomedical Research Institute, San Antonio, Texas. The male baboon used in this study was 18 yrs. old. The baboon had been raised and maintained on a standard monkey chow diet (high complex carbohydrates; low fat) prior to the fasting blood collection. All procedures involving animals were reviewed and approved by the Texas Biomedical Research Institute’s Institutional Animal Care and Use Committee (IACUC). Freshly collected serum samples were stored in aliquots at -80 C until analysis. |
