OAZ Regulates Bone Morphogenetic Protein Signaling through Smad6 Activation

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...

Hypoxia regulates bone morphogenetic protein signaling through C-terminal-binding protein 1.

Bone morphogenetic protein receptor 2 (BMPR2) mutations have been linked to familial pulmonary arterial hypertension (PAH), but the molecular pathways leading to this severe pathology remain poorly characterized. We report that hypoxia, a paramount stimulus for the development of pulmonary hypertension, suppresses the expression of inhibitor of differentiation 1 (Id1), a downstream target of th...

Regulates Early Thymocyte Differentiation Bone Morphogenetic Protein 2/4 Signaling

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...

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....
