Myocardin-related transcription factor-a controls myofibroblast activation and fibrosis in response to myocardial infarction.
RATIONALE Myocardial infarction (MI) results in loss of cardiac myocytes in the ischemic zone of the heart, followed by fibrosis and scar formation, which diminish cardiac contractility and impede angiogenesis and repair. Myofibroblasts, a specialized cell type that switches from a fibroblast-like state to a contractile, smooth muscle-like state, are believed to be primarily responsible for fib...
متن کاملA myocardin-related transcription factor regulates activity of serum response factor in Drosophila.
Serum response factor (SRF) regulates genes involved in cell proliferation, migration, cytoskeletal organization, and myogenesis. Myocardin and myocardin-related transcription factors (MRTFs) act as powerful transcriptional coactivators of SRF in mammalian cells. We describe an MRTF from Drosophila, called DMRTF, which shares high homology with the functional domains of mammalian myocardin and ...
متن کاملAMP-activated protein kinase/myocardin-related transcription factor-A signaling regulates fibroblast activation and renal fibrosis.
Chronic kidney disease is a major cause of death, and renal fibrosis is a common pathway leading to the progression of this disease. Although activated fibroblasts are responsible for the production of the extracellular matrix and the development of renal fibrosis, the molecular mechanisms underlying fibroblast activation are not fully defined. Here we examined the functional role of AMP-activa...
متن کاملMyocardin-related transcription factor-A: mending a broken heart.
Ventricular remodeling following myocardial infarction (MI) is a complex process driven by the response of both the myocytic and the nonmyocytic components of the heart to dynamic mechanical and neurohumoral stimuli. Despite the advent of reperfusion therapy and the administration of drugs slowing the progression of heart failure, many patients experiencing a MI undergo a progressive decline in...
متن کاملMyocardin-related transcription factor A mediates OxLDL-induced endothelial injury.
RATIONALE Atherosclerosis proceeds through a multistep reaction that begins with endothelial injury caused by a host of stress signals, among which oxidized low-density lipoprotein (oxLDL) plays a critical role. OxLDL disrupts normal functionality of the endothelium by upregulating adhesion molecules (eg, ICAM-1) and concomitantly downregulating endothelial nitric oxide synthase (eNOS) expressi...
