Could a pill replace exercise? Scientists make bold claim about new protein

Benefits of exercise can come in a pill one day

It's been revealed that there are a few details that have to be researched more on this issue, but researchers at the University of MI said that the naturally occurring protein called Sestrin seems to be mimicking the effects of exercise on both mice and flies in experiments.

Lee is a professor in the Department of Molecular and Integrative Physiology at the University of MI.

The study could prove significant for the growing aging population who might be concerned about health and mobility.

This "underlines that sestrin alone is enough to bring many benefits from exercise and movement", said Lee. But endurance exercise isn't suitable for everyone. "Therefore, generation of therapeutic mimetics to induce the benefits of exercise could provide broad ranging benefits to the medical community, " the researchers noted.

Kim, professor Jun Hee Lee, and a group of researchers wanted to learn more about the exercise effect of protein, and they first started working on flies. The contraption was used to capture the natural impulse of flies to climb up and out of test tubes. The team trained the flies for about 3 weeks and compared their running and flying abilities with those of the cestrin-hindered flies.


Sestrin, which is produced naturally during exercise, was found in tests to be the reason that physical activity burns fat, builds our muscles and improves our breathing.

When the researchers overexpressed Sestrin in the muscles of normal flies, essentially maxing out their Sestrin levels, they found those flies had abilities above and beyond the trained flies, even without exercise. Primarily, after exercising mice might perchance well also merely nonetheless demand their respiratory, corpulent burning, and aerobic skill pork up, but this personnel of mice saw no such enhancements after exercising. "This roughly blended designate is most considerable for producing exercise's results".

The researchers demonstrated that muscle-specific Sestrin can also help prevent atrophy in a muscle that's immobilised, such as the type that occurs when a limb is in a cast for a long period of time. As such, don't query any Sestrin dietary supplements anytime rapidly. Researchers are working to find small molecule regulators of protein.

Scientists still don't know how exercise produces cestrin in the body, and cestrins are not small molecules.

"Here's extremely extreme for future notion and might perchance well also lead to a medicines for folk that can not exercise", Kim concludes.
