Study TitleA cross-sectional study of functional and metabolic changes during aging through the lifespan in male mice (Muscle) part-I
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.

Make sure that the nitrogen line was flushed out of air before using it for degassing the extraction solvent solution Sample Preparation Weigh 50 mg tissue sample in to a 25 ml conical polypropylene centrifuge tube. Add 2.5mL extraction solvent to the tissue sample and homogenize for 45 seconds ensuring that sample resembles a powder. In between samples, clean the homogenizer in solutions of methanol, acetone, water, and the extraction solvent. Centrifuge the samples at 2500 rpm. for 5 minutes. Aliquot 2 X 500µl supernatant, one for analysis and one for a backup sample. Store backup aliquot in the -20°C freezer. Evaporate one 500µl aliquot of the sample in the Labconco Centrivap cold trap concentrator to complete dryness The dried aliquot is then re-suspended with 500?l 50% acetonitrile (degassed as given) Centrifuge for 2 min at 14000 rcf using the centrifuge Eppendorf 5415.
