Valvular myofibroblast activation by transforming growth factor-beta: implications for pathological extracellular matrix remodeling in heart valve disease.
The pathogenesis of cardiac valve disease correlates with the emergence of muscle-like fibroblasts (myofibroblasts). These cells display prominent stress fibers containing alpha-smooth muscle actin (alpha-SMA) and are believed to differentiate from valvular interstitial cells (VICs). However, the biological factors that initiate myofibroblast differentiation and activation in valves remain unid...
متن کاملInhibition of myofibroblast apoptosis by transforming growth factor beta(1).
Fibroblast differentiation to the myofibroblast phenotype is associated with alpha-smooth-muscle actin (alpha-SMA) expression and regulated by cytokines. Among these, transforming growth factor (TGF)-beta(1) and interleukin (IL)-1beta can stimulate and inhibit myofibroblast differentiation, respectively. IL-1beta inhibits alpha-SMA expression by inducing apoptosis selectively in myofibroblasts ...
متن کاملTransforming growth factor-β
Dna2 was first characterized in yeast as an essential gene encoding a protein with both helicase and endonuclease activities involved in maturation of Okazaki fragments during DNA replication. Dna2 also plays a role in double-strand break (DSB) repair by homolo-gous recombination. The respective contributions of its replication and/or repair functions toward cell viability and resistance to gen...

متن کاملNormal Human Lung Epithelial Cells Inhibit Transforming Growth Factor-β Induced Myofibroblast Differentiation via Prostaglandin E2
INTRODUCTION Idiopathic pulmonary fibrosis (IPF) is a chronic progressive disease with very few effective treatments. The key effector cells in fibrosis are believed to be fibroblasts, which differentiate to a contractile myofibroblast phenotype with enhanced capacity to proliferate and produce extracellular matrix. The role of the lung epithelium in fibrosis is unclear. While there is evidence...
