OBJECTIVE Studies in rodent models have suggested that reduction in renal transforming growth factor (TGF)-beta1 may underlie the renoprotective effects of the renin-angiotensin system (RAS) blockade. However, the role of the RAS blockade in abrogating TGF-beta in human disease is unknown. Accordingly, we sought to examine TGF-beta gene expression and biological activity in human renal biopsies...
OBJECTIVE Overexpression of transforming growth factor-beta 2 has been associated with craniosynostosis and resynostosis following surgery. We examined the effects of localized transforming growth factor-beta 2 inhibition on craniofacial phenotype in rabbits with craniosynostosis. DESIGN Twenty-five New Zealand white rabbits with bilateral coronal craniosynostosis were divided into three trea...
Previous studies have demonstrated that angiotensin II stimulates expression of transforming growth factor-beta (TGF-beta) in cultured renal cells. To investigate whether similar mechanisms are operative in vivo, glomerular TGF-beta mRNA expression was investigated in two-kidney, one-clip (2-K 1-C) hypertensive rats. Glomerular TGF-beta1 transcripts were elevated in the clipped kidney 6 d, but ...
Integrin heterodimers which share a common beta 1 subunit are the major cellular receptors for many extracellular matrix proteins. Here, we show that two inflammatory mediators, interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), can regulate the expression of the alpha 1 beta 1 integrin heterodimer, known to be a laminin and collagen receptor. In human skin fibroblasts ...
The responses of articular chondrocytes to physicochemical stimuli are intimately linked to processes that can lead to both degenerative and regenerative processes. Toward understanding this link, we examined the biomechanical behavior of single chondrocytes in response to growth factors (IGF-I and TGF-beta1) and a range of compressive strains. The results indicate that the growth factors alter...
The fibrillins and latent transforming growth factor-beta binding proteins (LTBPs) form a superfamily of structurally-related proteins consisting of calcium-binding epidermal growth factor-like (cbEGF) domains interspersed with 8-cysteine-containing transforming growth factor beta-binding protein-like (TB) and hybrid (hyb) domains. Fibrillins are the major components of the extracellular 10-12 ...
