Myocardin-Related Transcription Factor A Mediates OxLDL-Induced Endothelial Injury

Myocardin-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...

Molecular Medicine Myocardin-Related Transcription Factor A Mediates OxLDL-Induced Endothelial Injury

Myocardin-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...

Myocardin-related transcription factor A cooperates with brahma-related gene 1 to activate P-selectin transcription

Expression of P-selectin in injured or activated endothelia cells serves as a permissive step towards leukocyte recruitment and perpetuation of inflammation in the pathogenesis of atherosclerosis. P-selectin can be induced by pro-inflammatory stimuli via the transcription factor NF-kB, but the epigenetic mechanisms remain incompletely understood. Previously we reported that myocardin-related tr...

A Role of Myocardin Related Transcription Factor-A (MRTF-A) in Scleroderma Related Fibrosis

In scleroderma (systemic sclerosis, SSc), persistent activation of myofibroblast leads to severe skin and organ fibrosis resistant to therapy. Increased mechanical stiffness in the involved fibrotic tissues is a hallmark clinical feature and a cause of disabling symptoms. Myocardin Related Transcription Factor-A (MRTF-A) is a transcriptional co-activator that is sequestered in the cytoplasm and...
