Transforming growth factor-beta (TGF-beta)/Smads regulate a wide variety of biological responses through transcriptional regulation of target genes. Smad3 plays a key role in TGF-beta/Smad-mediated transcriptional responses. Here, we show that the proline-rich linker region of Smad3 contains a transcriptional activation domain. When the linker region is fused to a heterologous DNA-binding domai...
Unilateral ureteral obstruction (UUO) induces activation of the renin-angiotensin system and upregulation of transforming growth factor-beta1 (TGF-beta1; a cytokine modulating cellular adhesion and fibrogenesis) and clusterin (a glycoprotein produced in response to cellular injury). This study was designed to examine the regulation of renal TGF-beta1 and clusterin by ANG II in the neonatal rat....
BACKGROUND Transforming growth factor-beta1 (TGF-beta1) is the major profibrotic cytokine involved in many renal diseases, and urinary TGF-beta1 reflects intrarenal TGF-beta1 production. Urinary TGF-beta1 excretion is reported to be significantly increased in patients with immunoglobulin A (IgA) nephropathy. The aim of the present study was to compare the effects of losartan and amlodipine on p...
Angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists attenuate fibrosis in the kidney, heart, and liver by suppressing transforming growth factor-beta1 mRNA and decreasing production of extracellular matrix proteins. We recently demonstrated that lisinopril, an angiotensin-converting enzyme inhibitor, alleviates pancreatic inflammation and fibrosis in male Wistar Bonn/K...
Osteopontin (OPN) is a multifunctional cytokine that is strongly expressed in healing wounds and fibrotic lesions, both of which are characterized by the formation of myofibroblasts. We examined the role of OPN in myofibroblast differentiation induced by the profibrotic cytokine transforming growth factor-beta1. In cultured cardiac or dermal fibroblasts treated with transforming growth factor-b...
Transforming growth factor-beta1 and its subtype receptor endoglin are key components in angiogenesis. We explored the role of angiotensin (Ang) II in the expression of endoglin and the underlying intracellular signaling mechanism in human coronary artery endothelial cells. Incubation of cells with Ang II upregulated endoglin expression in a concentration- and time-dependent manner (maximal eff...
