Bone Morphogenetic Protein 2/4 Signaling Regulates Early Thymocyte Differentiation

Regulates Early Thymocyte Differentiation Bone Morphogenetic Protein 2/4 Signaling

OAZ regulates bone morphogenetic protein signaling through Smad6 activation.

The intensity and duration of activation of a signal transduction system are important determinants of the specificity of the cellular response to the stimulus. It is unclear how different cells can generate a signal of varying intensity and duration in response to the same cytokine. We investigated the role of the transcriptional activator and Smad1/4 cofactor OAZ in regulating bone morphogene...

Bone morphogenetic protein signaling in articular chondrocyte differentiation.

Articular chondrocytes progressively undergo dedifferentiation into a spindle-shaped mesenchymal cellular phenotype in monolayers. Chondrocyte dedifferentiation is stimulated by retinoic acid. On the other hand, bone morphogenic proteins (BMPs) stimulate differentiation of chondrocytes. We examined the mechanism of effects of BMP in chondrocyte differentiation with use of a recombinant adenovir...

Interplay between electrical activity and bone morphogenetic protein signaling regulates spinal neuron differentiation.

A gradient of bone morphogenetic proteins (BMPs) along the dorsoventral axis of the spinal cord is necessary for the specification of dorsal neurons. Concurrently, a gradient of calcium-mediated electrical activity is present in the developing spinal cord but in an opposing ventrodorsal direction. Whether BMPs and electrical activity interact in embryonic spinal neurons remains unknown. We show...

Bone Morphogenetic Protein Signaling: Implications in Urology

The bone morphogenetic proteins (BMPs), as members of the transforming growth factor-beta (TGF-beta) superfamily, not only control bone formation, but also regulate multiple key steps during embryonic development and differentiation. Furthermore, BMPs play critical roles in maintaining the homeostasis of the cardiovascular, pulmonary, reproductive, urogenital, and nervous systems in adult life....
