Expression of peroxisome proliferator-activated receptor-gamma in vascular smooth muscle cells is upregulated in cystic medial degeneration of annuloaortic ectasia in Marfan syndrome.

BACKGROUND Cystic medial degeneration (CMD) is a histological abnormality that is common in annuloaortic ectasia (AAE) and aortic dissection with Marfan syndrome. Apoptosis and loss of vascular smooth muscle cells (VSMCs) is one of the features of CMD, but little is known about its pathogenesis. Peroxisome proliferator-activated receptor-gamma (PPARgamma… (More)
