Bone morphogenic protein-7 inhibits monocyte-stimulated TGF-beta1 generation in renal proximal tubular epithelial cells.
It has been demonstrated that bone morphogenic protein-7 (BMP-7) stimulates formation of hyaluronan (HA)-based cables on the cell surface of renal proximal tubular cells and that these cables mediate monocyte binding. Furthermore, interaction of monocytes with proximal tubule cell (PTC) surface intracellular adhesion molecule (ICAM) stimulates the synthesis of TGF-beta1. This study examined the...
متن کاملLoss 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 کاملBMP-7 enhances SnoN mRNA expression in renal tubular epithelial cells under high-glucose conditions
The present study aimed to identify any association between bone morphogenetic protein‑7 (BMP‑7) and the expression of the transcriptional co‑repressor Ski‑related novel protein N (SnoN), in addition to alterations in tubulointerstitial fibrosis, during the development and progression of diabetic nephropathy (DN). Streptozotocin was injected into the tail veins of 20 healthy and specific pathog...
متن کاملSnoN Stabilizes the SMAD3/SMAD4 Protein Complex
TGF-β signaling regulates cellular processes such as proliferation, differentiation and apoptosis through activation of SMAD transcription factors that are in turn modulated by members of the Ski-SnoN family. In this process, Ski has been shown to negatively modulate TGF-β signaling by disrupting active R-SMAD/Co-SMAD heteromers. Here, we show that the related regulator SnoN forms a stable comp...
متن کاملBone morphogenetic protein-7 expression in human pyelonephritis.
Bone morphogenetic protein 7 (BMP- 7) is a member of the transforming growth factor (TGF) beta superfamily and is involved in regeneration, repair, and development of specific tissues, for example kidney and skeleton. The experimental studies have shown its protective role against fibrotic processes. Tubulointerstitial changes are present in the pyelonephritic kidney which progresses to fibrosi...
