RATIONALE Matrix Gla protein (MGP) is a calcification inhibitor, which binds and inhibits bone morphogenetic protein (BMP)-2 and -4. OBJECTIVE The objective was to determine whether MGP also binds other proteins, which could interfere with its function. METHODS AND RESULTS We transfected bovine aortic endothelial cells with N-terminally FLAG-tagged MGP and used immunoprecipitation and liqui...
The formation of periodic patterns is fundamental in biology. Theoretical models describing these phenomena have been proposed for feather patterning; however, no molecular candidates have been identified. Here we show that the feather tract is initiated by a continuous stripe of Shh, Fgf-4, and Ptc expression in the epithelium, which then segregates into discrete feather primordia that are mor...
The transforming growth factor-beta superfamily is thought to be involved in the regulation and control of growth and differentiation. These growth factors signal through transmembrane serine/threonine kinase receptors. The activation of type I receptor kinase phosphorylates a family of intracellular signalling proteins called Smads. In the present study, we wanted to localize type I and type I...
Fibrosis is a scarring process that is a common feature of chronic organ injury. It is characterized by elevated activity of transforming growth factor-beta resulting in increased and altered deposition of extracellular matrix and other fibrosis-associated proteins. Recent work has demonstrated that bone morphogenetic protein-7 blocks transforming growth factor-beta signaling. Moreover, member ...
