Pretty cool and surprising findings on different myonuclear populations and mononuclear cell behavior, e.g. in multicellular crosstalk using fixed tissue sequencing, minimizing cell activation by enzymatic digestion. Work led by @sedatdilbaz.bsky.social @biozentrum.unibas.ch @unibas.ch.

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.

The first time Charlie Chaplin used his voice in a film, he wielded it to forcefully condemn the rising forces of fascism around the globe.

Will we listen to his words today?

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.

Now out in the typeset, final version! #openaccess

Resist, eggheads! Universities are not as weak as they have chosen to be. Opinion: It’s time for public resistance.

"This moment calls out for moral clarity and resolve. It asks universities to take their mission in society seriously and to resist being co-opted by government forces."

This and much more! This review is an extension of, and complementary to our previous commentary in NPJ Aging (doi.org/10.1038/s415...), and the discussion in our review in the Journal of Physiology @physoc.bsky.social (doi.org/10.1113/jp28...).

9/9

Changes that could improve healthy aging.

8.) Our current health care setting fails to prioritize such measures. What could be done to improve the situation? On the level of the individual person, health care professionals, health insurance providers, society and politics. How could we pay for this?

8/9

Various biomarkers of aging, with different degrees of clinical evidence.

7.) In contrast for physiological, functional and anthropometric biomarkers, solid and broad human data exist! E.g. #VO2max, body composition (muscle and #fat mass/distribution), #muscle force and power, activity levels, gait speed and other frailty markers.

7/9

Molecular "clocks" and biomarkers of aging.

6.) How measure aging trajectories or "biological age"? Current state of molecular #biomarkers, e.g. #epigenetic marks, plasma proteomics or #telomere length.

6/9

Modifiers of healthy aging with solid and broad data in humans.

5.) What does work? Interventions with solid data on human aging, #morbidity, #mortality and/or #longevity: physical activity, #sleep, #nutrition, #stress, social interactions, socioeconomic disparities, #climatechange and much more!

5/9

Molecular and cellular hallmarks of aging, and the proposed drugs and interventions that could modify these.

4.) Proposed "#anti-aging drugs" and interventions in human aging, e.g. #rapamycin, #metformin, #resveratrol, but also #reprogramming, #rejuvenation, #caloric restriction. Potentially negative effects on other health-beneficial interventions (e.g. #exercise).

4/9

Old (left side) and young (right side) mouse.

2.) How to study aging? E.g. Genetic diseases of "accelerated aging" (e.g. #progeria), (super-) #centenarians and geography (e.g. in a so-called #BlueZone).

3.) How might human aging differ from that in animals? What could this mean for the study of model organisms in this field?
