Understanding how exercise induces systemic metabolic benefits

Posted by in categories: biotech/medical, health

Northwestern Medicine scientists have uncovered a mechanism by which exercise activates metabolic benefits in the body, according to a new study published in Cell Metabolism.

It’s well known that exercise elicits many . However, how this is accomplished is not yet well understood. During exercise, , the body’s cellular recycling system that allows old or damaged cellular structures to be broken down, is activated in both contracting muscles and various non-contracting organs, such as the liver.

In the study, investigators performed proteomic analyses on the blood of mice before and after exercise. They identified a protein secreted from contracting muscle, FN1, which significantly increased in the plasma and serum of mice after exercise.
