Angiogenic function of prostacyclin biosynthesis in human endothelial progenitor cells.

abstract：:Dystrophin has a key role in striated muscle mechanotransduction. In mice lacking the gene encoding for dystrophin (mdx mice), the absence of dystrophin and several other proteins of the dystrophin-glycoprotein complex induces a defect in flow (shear stress)-mediated NO-dependent dilation (FMD). Because the endotheliu...
