Figure 1 GDF11 Total Protein Levels and Mechanism Myostatin, GDF11, and activin signal through the ActRII/Alk4,5 complex, inducing SMAD2 and SMAD3 phosphorylation. This results in a decrease in skeletal muscle growth. Schafer et al. (2016) find high levels of GDF11 to be associated with frailty and other co-morbidities of the aged. In human beings, GDF11 is not regulated by age, whereas myostatin decreases in males. Cell Metabolism 2016 24, 7-8DOI: (10.1016/j.cmet.2016.06.017) Copyright © 2016 Elsevier Inc. Terms and Conditions
