The myostatin/activin type II receptor (ActRII) pathway has been identified to be critical in regulating skeletal muscle size. Several other ligands, including GDF11 and the activins, signal through this pathway, suggesting that the ActRII receptors are major regulatory nodes in the regulation of muscle mass. We have developed a novel, human anti-ActRII(More)
The expression of the bone morphogenetic protein antagonist, Gremlin 1, was recently shown to be increased in the lungs of pulmonary arterial hypertension patients, and in response to hypoxia. Gremlin 1 released from the vascular endothelium may inhibit endogenous bone morphogenetic protein signaling and contribute to the development of pulmonary arterial(More)
