Muscle Fiber- and Cell Type-Specificity of Training Adaptation in Male Mice Skeletal muscle possesses extraordinary plasticity of structure, metabolism, and function in response to repeated contractile activity. As a syncytium embedded within a complex microenvironment, muscl...

If so, you might want to read our new preprint on @biorxivpreprint.bsky.social! We repeated this experiment (acute exercise in untrained and trained mice, analyzed at different time points, comparison of untrained and trained at rest) on the single nucleus level.

Biomarkers of aging: from molecules and surrogates to physiology and function | Physiological Reviews | American Physiological Society Many countries face an unprecedented challenge in aging demographics. This has led to an exponential growth in research on aging, which, coupled to a massive financial influx of funding in the private and public sectors, has resulted in seminal insights into the underpinnings of this biological process. However, critical validation in humans has been hampered by the limited translatability of results obtained in model organisms, additionally confined by the need for extremely time-consuming clinical studies in the ostensible absence of robust biomarkers that would allow monitoring in shorter time frames. In the future, molecular parameters might hold great promise in this regard. In contrast, biomarkers centered on function, resilience, and frailty are available at the present time, with proven predictive value for morbidity and mortality. In this review, the current knowledge of molecular and physiological aspects of human aging, potential antiaging strategies, and the basis, evidence, and potential application of physiological biomarkers in human aging are discussed.
