Study TitleModel-driven multi-omic data analysis elucidates metabolic immunomodulators of macrophage activation
Study Typegrowth condition, timecourse
Study SummaryMacrophages are central players in immune response, manifesting divergent phenotypes to control inflammation and innate immunity through release of cytokines and other signaling factors. Recently, the focus on metabolism has been reemphasized as critical signaling and regulatory pathways of human pathophysiology, ranging from cancer to aging, often converge on metabolic responses. Here, we used genome-scale modeling and multi-omics (transcriptomics, proteomics, and metabolomics) analysis to assess metabolic features that are critical for macrophage activation. A genome-scale metabolic network for the RAW 264.7 cell line was constructed to determine metabolic modulators of activation. Metabolites well-known to be associated with immunoactivation (glucose and arginine) and immunosuppression (tryptophan and vitamin D3) were among the most critical effectors. Intracellular metabolic mechanisms were assessed, identifying a suppressive role for de-novo nucleotide synthesis. Finally, underlying metabolic mechanisms of macrophage activation were identified by analyzing multi-omic data obtained from LPS-stimulated RAW cells in the context of our flux-based predictions. This study demonstrates that the role of metabolism in regulating activation may be greater than previously anticipated and elucidates underlying connections between activation and metabolic effectors. This submission corresponds to the metabolomics data from this study.

Sample Preparation:

Sampleprep ID:SP000099
Sampleprep Summary:Suspentions softly centrifuged, buffer removed, amonium bicarbonate added, metabolites extraxted with chloroform/methanol (2:1, v/v), vortexed, centrifuged, aqueous layer dried in vacuum concentrator, derivatization with methoxyamine in pyridine, N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA), and 1% trimethylchlorosilane (TMCS)
Sampleprep Protocol Comments:Cell suspensions were softly centrifuged (230 × g for 5 min) and as much buffer as possible was removed. Then, 170 µL of 150 mM ammonium bicarbonate was added to the cell pellet and the cell suspensions were transferred to 2 mL micro-centrifuge tubes for extraction. Subsequently, the water soluble metabolites were extracted with four volumes of chilled (-20°C) chloroform/methanol (2:1, v/v). After vortexing, the samples were centrifuged (12,000 × g for 5 min) and the upper (aqueous) layers containing water-soluble metabolites were transferred into glass vials, followed by drying in a vacuum concentrator. For the derivatization, 20 µL of methoxyamine in pyridine (30 mg/mL) were added to each sample, followed by incubation at 37°C with shaking for 90 min to protect carbonyl groups. Next, 80 µL of N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) with 1% trimethylchlorosilane (TMCS) were added to each vial, followed by incubation at 37°C with shaking for 30 min to derivatize hydroxyl and amine groups. The samples were then allowed to cool to room temperature.

Chromatography ID:CH000096
Chromatography Summary:Agilent 7890A gas chromatograph with a HP-5MS gas chromatography column using Chemstation
Chromatography Comments:Chromatography was carried out on an Agilent 7890A gas chromatograph using the manufacturer's software (Chemstation) and a HP-5MS gas chromatography column (Agilent Technologies, Santa Clara, CA; 30 m x 0.25 mm x 0.25 m film thickness). The sample injection mode was splitless, and 1 L of each sample was injected. The injection port temperature was held at 250 C throughout the analysis. The GC oven was held at 60 C for 1 min after injection, and the temperature was then increased to 325 C by 10 C/min, followed by a 5 min hold at 325 C. The helium gas flow rates for each Experiment were determined by the Agilent Retention Time Locking function based on analysis of deuterated myristic acid and were in the range of 0.450.5 mL/min.
