“The prevention of muscle atrophy and muscle regrowth in mice was shown to be dependent on the robust activation of heat shock proteins. These proteins are highly conserved in humans in function, playing an extremely apparent similar molecular role.”

“In older adults, however, levels only increased after 12 weeks of consistent training. The researchers linked this diminished response to a decline in cytokine receptor-like factor 1, a companion protein required for the myokine's release.”

“Interestingly, whole-body heat inhibited the activity of some FOXO proteins and switched on the activity of some genes involved in atrophy. Further study is needed to determine the full effects of whole-body hyperthermia on muscle atrophy.”

“Dr. Patrick presents these compounds as tools for selected goals rather than universal essentials, alongside a stronger foundation of exercise, sufficient protein and energy, sleep, vaccination, and appropriate medical care.”

“In two separate articles scientists report that injections of a protein known as GDF11, which is found in humans as well as mice, improved the exercise capability of mice equivalent in age to that of about a 70-year-old human.”

“The observed increase in protein persulfidation offers a possible explanation for these changes, as it can directly alter how proteins involved in metabolism and stress responses function. The study has important limitations.”

“Force “opens” the titin protein structure, exposing a molecular site for phosphorylation (i.e., adding a phosphate group). This phosphorylation initiates a signaling cascade that results in changes to gene expression that affect long-term growth and atrophy of skeletal muscles.”

“Nrf2 activates the transcription of cytoprotective proteins that protect against oxidative stress due to injury and inflammation. The study investigators gauged the effects of curcumin in mice that had heart failure with reduced ejection fraction and in mice with healthy hearts.”

“A separate study in older adults found greater amino-acid and insulin-stimulated muscle protein synthesis after omega-3 supplementation. These findings make omega-3 status especially relevant during injury, surgery, or other periods when regular training is not possible.”

“It also improved insulin sensitivity and increased mitochondrial proteins and ribosomes (which make new proteins) in muscle cells. The volunteers engaged in aerobic high-intensity interval training (cycling at >90% of peak oxygen consumption) for 3 days and 2 days per week of treadmill walking (45 min at 70% of VO2 peak) or strength training.”
