Sarcopenia and cachexia are two muscle-wasting disorders characterized by oxidative stress and inflammation, which means that regulating molecules are increased in expression (e.g., members of the ubiquitin–proteasome system, myostatin, apoptosis-inducing factors), whereas other factors (e.g., IGF-1) are down-regulated [50,51]. Here, IGF1 is linked to Cachexia.
