1/ Why do muscles atrophy with aging and disuse?
Is it because each tiny little myofibril gets smaller… or is it because we lose myofibrils?
In our new study, we addressed this in humans and mice. biorxiv.org/cgi/content/sh…
Full breakdown of the findings in this thread 👇
In 1990, as Voyager 1 was leaving the solar system, Sagan fought a long internal battle at NASA to turn the cameras around one last time to photograph Earth. Many engineers opposed it, fearing it might damage the cameras or waste time.
But Sagan’s successful effort resulted in the "Pale Blue Dot" image. He used this tiny, 0.12-pixel speck of Earth to write his famous reflection on how "every human being who ever was" lived on that "mote of dust suspended in a sunbeam".
Very excited to share some of our recent work studying primary human MPCs from patients with late stage CKD! We identify metallothionein-induced zinc deficiency as a contributor to attenuated myogenesis in this population.

Upcoming Postdoc Position! With Chris Nelson’s lab at U of A, we are looking for a fully supported 2-year postdoc to work on muscle gene editing and detection of gene doping in vivo. If interested, email myself and Chris: kmurach@uark.edu and nelsonc@uark.edu #myotwitter
A heavy lift from a literal strongman, PhD candidate @PJKoopmans “The Age-Dependent Resident Myonuclear Multi-Omic Response to a Skeletal Muscle Hypertrophic Stimulus” 💪🏻 biorxiv.org/content/10.110…
9/ Shoutout to co-first authors @jhibbert_phd and @kentjorgenson_ and the rest of the team pushing this 8-year-long project to the finish line. The next step is to get it published. Please give it a repost if you think it will be impactful for the field. biorxiv.org/content/10.110…

Edwin Krebs and Edmond Fischer showed how proteins in the muscle cell make the energy supply accessible for muscular work and how the breakdown of glycogen to glucose is controlled in the skeletal muscles.
