Loss of tubular bone morphogenetic protein-7 in diabetic nephropathy.
Bone morphogenetic protein-7 (BMP7), a member of the transforming growth factor-beta (TGF-beta) superfamily of cytokines, is highly expressed in renal tubules and generally promotes maintenance of epithelial phenotype. It was examined whether, during the evolution of experimental diabetic nephropathy, the renal expression of BMP7 and BMP7 receptors declines, and the hypothesis that loss of BMP7...
متن کاملBone Morphogenetic Protein 4 and Smad1 Mediate Extracellular Matrix Production in the Development of Diabetic Nephropathy.
Diabetic nephropathy is the leading cause of end-stage renal disease. It is pathologically characterized by the accumulation of extracellular matrix in the mesangium, of which the main component is α1/α2 type IV collagen (Col4a1/a2). Recently, we identified Smad1 as a direct regulator of Col4a1/a2 under diabetic conditions in vitro. Here, we demonstrate that Smad1 plays a key role in diabetic n...
متن کاملActivation 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...
متن کاملTrkC 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...
متن کاملOAZ 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...
