Visualizing Smad1/4 signaling response to bone morphogenetic Protein-4 activation by FRET biosensors

Activation of vascular bone morphogenetic protein signaling in diabetes mellitus.

RATIONALE Diabetes mellitus is frequently complicated by cardiovascular disease, such as vascular calcification and endothelial dysfunction, which have been associated with bone morphogenetic proteins (BMPs). OBJECTIVE To determine whether hyperglycemia in vitro and diabetes in vivo promote vascular BMP activity and correlate with vascular calcification. METHODS AND RESULTS Increased glucos...

TrkC binds to the bone morphogenetic protein type II receptor to suppress bone morphogenetic protein signaling.

TrkC, a member of the tropomyosin-related kinase (Trk) family of neurotrophin receptors, is implicated in the growth and survival of human cancer tissues. TrkC is also a potent oncoprotein expressed in tumors derived from multiple cell lineages, and functions as an active protein tyrosine kinase by neurotrophin-3 (NT-3). We previously reported that TrkC plays an essential role in tumor growth a...

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 4 (BMP4) signaling in retinoblastoma cells

Bone morphogenetic proteins (BMPs) - expressed in the developing retina - are known to be involved in the regulation of cell proliferation and apoptosis in several tumor entities. The objective of this study was to determine the role of the BMP4 pathway in retinoblastoma cells, which are absent in a functional retinoblastoma (RB1) gene. BMP receptors were detected in all retinoblastoma cell lin...
