Study TitleA cross-sectional study of functional and metabolic changes during aging through the lifespan in male mice (Serum) part-II
Study SummaryAging is associated with distinct phenotypical, physiological, and functional changes, leading to the onset of disease and death. The progression of aging-related traits varies widely among individuals, influenced by their environment, lifestyle, and genetics. In this study, we performed physiologic and functional tests cross-sectionally throughout the entire lifespan of male C57BL/6N mice. In parallel, metabolomics analyses in serum, brain, liver, heart, and skeletal muscle were also performed to identify signatures associated with frailty and age-dependent functional decline. Our findings indicate that the decline in gait speed as a function of age and frailty is associated with dramatic increases in the energetic cost of physical activity and decreases in working capacity. Aging and functional decline prompt organs to rewire their substrate selection and metabolism towards redox-related pathways, mainly in liver and heart. Collectively, the data provide a framework to further understand and characterize processes of aging at the individual and organ levels.

Sample Preparation:

Sampleprep ID:SP001783
Sampleprep Summary:Sample preparation of blood plasma or serum samples for GCTOF analysis Purpose: This SOP describes sample extraction and sample preparation for primary metabolism profiling by gas chromatography/time-of-flight mass spectrometry (GCTOF). References: Fiehn O, Kind T (2006) Metabolite profiling in blood plasma. In: Metabolomics: Methods and Protocols. Weckwerth W (ed.), Humana Press, Totowa NJ. Fiehn, O.

Starting material: Plasma/serum: 30 µL sample volume or aliquot Equipment: Centrifuge Eppendorf 5415 D Calibrated pipettes 1-200µL and 100-1000µL Multi-Tube Vortexer (VWR VX-2500) Orbital Mixing Chilling/Heating Plate (Torrey Pines Scientific Instruments) Speed vacuum concentration system (Labconco Centrivap cold trap) Nitrogen line with Pasteur pipette Chemicals and consumables: Product Manufacturer & Part Number Eppendorf tubes 1.5 mL, uncolored Eppendorf 022363204 Crushed ice UC Davis Water, LC/MS Grade Fisher Optima W6-4 Acetonitrile, LC/MS Grade Fisher Optima A955-4 Isopropanol, LC/MS Grade Fisher A461-4 pH paper 5-10 Millipore Sigma 1095330001 Bioreclamation human plasma (disodium EDTA) Bioreclamation HMPLEDTA Sample Preparation: Preparation of extraction solvent For 1 L of extraction solvent, combine 375 mL of acetonitrile, 375 mL of isopropanol, and 250 mL water in a 1 L bottle conditioned with the aforementioned chemicals. If a different total volume of extraction solvent is needed, simply mix acetonitrile, isopropanol, and water in volumes in proportion 3:3:2. Purge the extraction solution mix for 5 min with nitrogen with small bubbles. Make sure that the nitrogen line is flushed out of air before using it for degassing the extraction solvent solution. Store at -20°C until use. Note: if solvent freezes, sonicate until thawed and mix before use. Extraction Thaw raw samples at room temperature (or in the refrigerator at 4?C) and vortex 10 sec at low speed to homogenize. Aliquot 30 ?L of plasma sample into a 1.5 mL Eppendorf tube. Keep all samples on ice. Add 1 mL 3:3:2 (v/v/v) ACN:IPA:H2O extraction solvent (prechilled in a -20°C freezer). Vortex the sample for 10 sec. Shake for 5 min at 4°C using the Orbital Mixing Chilling/Heating Plate. Continue to keep all extracted samples on ice. Centrifuge samples for 2 min at 14000 rcf. Aliquot two 450 ?L portions of the supernatant into 1.5 mL Eppendorf tubes (one for analysis and one as a backup sample). Transfer 100 ?L of the remaining supernatant from each sample to a 2, 15, or 50 mL tube for pools, depending on number of samples in the study. Evaporate one 450 ?L aliquot of the sample in the Labconco Centrivap cold trap concentrator to complete dryness. Proceed with cleanup or store tubes at -20°C until cleanup. Pooling Transfer multiple 475 µL aliquots of pooled samples to 1.5 mL Eppendorf tubes, one aliquot for every 10 samples in the study. If there is still pool remaining, prepare additional aliquots for backup. Centrifuge pool samples for 2 min at 14000 rcf. Remove 450 µL supernatant to new 1.5 mL Eppendorf tube. Evaporate to complete dryness in the Labconco Centrivap cold trap concentrator. Proceed with cleanup or store tubes at -20°C until cleanup. Cleanup Resuspend the dried aliquot with 500 ?L 50:50 (v/v) ACN:H2O (degassed as given above) and vortex for about 10 sec. Centrifuge for 2 min at 14000 rcf. Remove 475 ?L supernatant to a new 1.5 mL Eppendorf tube. Evaporate the transferred supernatant to complete dryness in the Labconco Centrivap cold trap concentrator. Submit to derivatization (see SOP “Derivatization of GC Samples & Standards”) or store at -20°C until ready for analysis. Quality assurance For every 50 samples, perform one method blank negative control extraction by applying the total procedure (i.e. all materials and plastic ware) without biological sample. If no combined pool was made from the extracted samples, use one commercial plasma/serum pool sample per 10 authentic subject samples as control instead. Disposal of waste Collect all chemicals in appropriate bottles and follow the disposal rules. Collect residual plasma/serum samples in specifically designed red ‘biohazard’ waste bags.
