|---|
Bone morphogenetic proteins (BMPs) exhibit broad spectra of biological activities in various tissues, including bone, cartilage, blood vessels, heart, kidney, neurons, liver, and lung. BMPs are members of the transforming growth factor-β (TGF-β) family that bind to type II and type I serine-threonine kinase receptors, and transduce signals through Smad and non-Smad signaling pathways. Recent findings have revealed that BMP signaling is finely tuned by various mechanisms in both positive and negative fashions. Perturbations of BMP signaling pathways are linked to a wide variety of clinical disorders, including vascular diseases, skeletal diseases, and cancer. Administration of recombinant BMP ligands and increasing endogenous expression of BMPs provide therapeutic effects on some diseases. The recent development of BMP receptor inhibitors may also prove useful for some clinical diseases induced by hyperactivation of the BMP signaling pathways.
Key Words: BMP, GDF, TGF-β, Smad, serine-threonine kinase
