Transforming growth factor-beta function blocking prevents myocardial fibrosis and diastolic dysfunction in pressure-overloaded rats.
BACKGROUND Excessive myocardial fibrosis impairs cardiac function in hypertensive hearts. Roles of transforming growth factor (TGF)-beta in myocardial remodeling and cardiac dysfunction were examined in pressure-overloaded rats. METHODS AND RESULTS Pressure overload was induced by a suprarenal aortic constriction in Wistar rats. Fibroblast activation (proliferation and phenotype transition to...
متن کاملThe Role of Transforming Growth Factor Beta 1 (TGFβ1) in Nasal and Paranasal Sinuses Polyposis
Background and Objectives: Nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. Some studies showed that TGFβ1 had significant role in this pathogenesis. In this study, we investigated the roe of cytokines and mediators in polyp development. Material and Methods: In this case- control study, healthy nasal mucosal samples were obtained from 24 peopl...
متن کاملTransforming growth factor-beta and fibrosis.
Transforming growth factor-beta (TGF-beta), a prototype of multifunctional cytokine, is a key regulator of extracellular matrix (ECM) assembly and remodeling. Specifically, TGF-beta isoforms have the ability to induce the expression of ECM proteins in mesenchymal cells, and to stimulate the production of protease inhibitors that prevent enzymatic breakdown of the ECM. Elevated TGF-beta expressi...
متن کاملInhibition of transforming growth factor-beta signaling induces left ventricular dilation and dysfunction in the pressure-overloaded heart.
This study utilized a transgenic mouse model that expresses an inducible dominant-negative mutation of the transforming growth factor (TGF)-beta type II receptor (DnTGFbetaRII) to define the structural and functional responses of the left ventricle (LV) to pressure-overload stress in the absence of an intact TGF-beta signaling cascade. DnTGFbetaRII and nontransgenic (NTG) control mice (male, 8-...
متن کاملTransforming growth factor beta inhibits megakaryocyte growth and endomitosis.
Using a rat bone marrow culture system, the effect of transforming growth factor beta 1 (TGF beta 1) on megakaryocyte growth and endoreduplication has been studied. Purified human platelet TGF beta 1 inhibited the number of megakaryocytes that appeared in culture at a half-maximal concentration of 0.66 +/- 0.21 ng/mL and inhibited megakaryocyte endoreduplication at a half-maximal concentration ...
