| Study Title | A cross-sectional study of functional and metabolic changes during aging through the lifespan in male mice (Heart) part-IV |
| Study Summary | Aging 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. |
