Peroxisome proliferator-activated receptor-gamma agonists increase vascular endothelial growth factor expression in human vascular smooth muscle cells.

Vascular endothelial growth factor (VEGF), expressed in a variety of mesenchymal cells including vascular smooth muscle cells (VSMC), is a potent mitogen for endothelial cells, and is used clinically applied for ischemic disease of peripheral vessels. To determine whether peroxisome proliferator-activated receptor gamma (PPARgamma) regulates VEGF production in VSMC, we examined VEGF secretion from VSMC treated with PPAR agonists. Troglitazone increased VEGF secretion in a time- and dose-dependent manner (261 +/- 35% with 25 mM of troglitazone for 24 h), and also increased levels of VEGF mRNA. VEGF secretion was also increased by other PPARgamma agonists, pioglitazone, LY171883, and 15d-PGJ2 (224 +/- 17.1%, 247 +/- 36.8% and 171 +/- 7.8%, respectively), but not the PPARgamma agonists bezafibrate and Wy14643 (85.2 +/- 1.5%, 94.6 +/- 3.2, respectively). Our findings suggest that thiazolidinediones might be useful for the therapeutic angiogenesis for ischemic artery disease.[1]
